H50 SERIES GAS FRYERS

CHAPTER 1: SERVICE PROCEDURES

1.1 Functional Description

H50 Series fryers contain a welded stainless steel frypot that is directly heated by a high efficiency
infrared burner system requiring approximately 43% less energy than conventional burners to cook
the same volume.

Self-contained combustion chambers (referred to as “burners”) are fitted into rails attached to the
sides of the frypot, one on each side. Each combustion chamber is fitted with special ceramic tiles
that are heated by the burning of a forced air/gas mixture. The tiles transfer their heat to the frypot
by means of infrared radiation, providing much more constant and uniform heat dispersion over the
surface of the frypot than do conventional burners. Because less heat is lost to the atmosphere in the
process, compared to “open-burner” designs, less fuel is required to achieve and maintain a given
frypot temperature.

In full vat units, gas flow to both of the burners is regulated by one electromechanical gas valve. In
dual vat units, each burner has its own valve. All fryers in this series are equipped with 24VAC gas
valve systems, and all are configured with electronic ignition.

THE ELECTRONIC IGNITION SYSTEM

An ignition module mounted in the component box or

Inside the Ignition Module

“shield” (located behind the control panel) is connected to
an ignitor assembly at the burner. The ignition module
performs four important functions: it provides fuse
protection for the 24-volt circuit, provides an ignition

spark, supplies voltage to the gas valve, and proofs the
burner flame. The module contains a 4-second time delay
circuit and a coil that activates the gas valve. Three types

25 V +

Coil

are in use. A closed-box design is used in most fryers, but
in some fryers built for export the module resembles an
interface board. A single dual-spark module is used on
current production full-vat fryers. Two single-spark

GND

TD

HV

modules were used on full-vat fryers built before August

2000. All dual-vat fryers use two single-spark modules.

Ignition Wire Flame Sensor

The ignitor assembly consists of a spark plug, an enrichment tube, and a flame sensor.

At start-up, the power switch is placed in the ON position, supplying approximately 12-volts DC to
the heat control circuitry in the controller or computer and to one side of the heat relay coils on the
interface board. If resistance in the temperature probe indicates the temperature in the frypot is
below 180ºF (82ºC), the current flows through a melt cycle circuit where a timer switch alternately
closes for 6 seconds and opens for 24 seconds. If the temperature is 180ºF (82ºC) or above, the
current flows through a heat circuit, bypassing the timer switch. In either case, ground is supplied
to

1-1

the other leg of the heat relay coils, which then close electronic switches in the 24 VAC circuit to
provide current to the ignition module. Circuitry in the ignition module sends 24 VAC to the gas
valve via a normally closed high-limit switch (and, in fryers with built-in filtration systems, a
normally closed drain safety switch). Simultaneously, the module causes the ignitor to spark for 4
seconds to light the burner. A flame sensor verifies the burner ignition by measuring the flow of
microamps through the flame. If the burner does not light (or is extinguished), current to the
ignition module is cut, the gas valve closes, and the ignition module “locks out” until the power
switch is turned off and then back on. A probe monitors the temperature in the frypot. When the
programmed setpoint temperature is reached, resistance in the probe causes the heat cycle circuitry
in the controller to cut off current flow through the heat relay. This in turn cuts off the 24 VAC to
the ignition module, causing the gas valve to close.

INTERFACE BOARDS

All fryers in this series have an interface board located in the component box located behind the
control panel. The interface board provides a link between the controller/computer and the fryer’s
individual components without requiring excessive wiring, and allows the controller to execute
commands from one central point. The H50 Series of fryers has been in production since 1983.
Consequently, servicers are likely to encounter three different interface board designs. Although the
boards differ slightly in appearance, basic functioning and electrical connections are the same from
one to another. In the earlier design 806-3398 interface board (used between June 1996 and July

1999), the diagnostic LEDs are arrayed in a row across the bottom of the board as shown in the left­hand illustration below. In later design 806-3398 interface boards (and in the 106-0396 interface
boards that replaced them in current production fryers), the LEDs (labeled D1 though D7) are
scattered around the board as shown in the right-hand illustration. The primary difference between
the earlier design boards and the later design boards is the combining of the separate blower motor
relay (K4) and the heat relays (K1 and K2) into a pair of replaceable relays (K2 and K3) in the latter.
Also, the 106-0386 interface board has an additional fuse located in the upper right hand corner.
Prior to June 1996, a board with replaceable relays very similar in appearance to the 106-0386 board
was used. It is distinguished from the 106-0386 board by the absence of fuses.

NOTE: Although the printing on many boards indicates 2 Amp fuses, 3 Amp fuses (P/N 807-3843)
must be used.

These standard interface boards are also used in a number of fryer types besides the H50 Series. The
information contained in this section applies to H50 Series applications ONLY.

Earlier design 806-3398 boards (used from June 1996 through July 1999) contain two heat relays
(K1 and K2) that switch 24VAC to the ignition and gas valve circuits when the computer/controller
heat logic circuit calls for heat. Relay K4 switches 120VAC to the blower motor when either K1 or
K2 closes. The relays on these boards are soldered on – if one fails, the whole board must be
replaced.

The later design 806-3398 (and 106-0386 boards that replaced them in current production fryers)
have only two relays. In this design, K2 and K3 are double-pole-double-throw (dpdt) relays that
supply 24VAC to the ignition and gas valve circuits, as well as 120VAC to the blower motor. The
relays on this board plug into sockets. If a relay fails, that relay can be replaced.

The tables below identify the diagnostic LEDs and their meaning.

THERMOSTATS

All fryers in the H50 Series have temperature probes located on the front centerline of each frypot.
(Dual-vat frypots have two probes, one in each vat.) In this type thermostat, the probe resistance
varies directly with the temperature. That is, as the temperature rises, so does resistance, at a rate of
approximately 2 ohms for every 1º F. Circuitry in the controller monitors the probe resistance and
controls burner firing when the resistance exceeds or falls below programmed temperatures
(setpoints). The temperatures are programmed by means of a keypad on the face of the controller.

H50 Series fryers are also equipped with a high-limit thermostat. In the event that the fryer fails to
properly control the oil temperature, the high-limit thermostat prevents the fryer from overheating to
the flash point. The high-limit thermostat acts as a normally closed power switch that opens when
exposed to temperatures above 425ºF to 450ºF (218ºC to 232ºC). The different types of thermostats
have different part numbers for CE and Non-CE models, and are not interchangeable.

1.2 Accessing Fryers for Servicing

DANGER

Moving a fryer filled with cooking oil may cause spilling or splattering of the hot

liquid. Drain the fryer before attempting to relocate a fryer for servicing.

1. Shut off the gas supply to the unit. Unplug the power cords. Disconnect the unit from the gas

supply.

2. Remove any attached restraining devices.

3. Relocate the fryer for service accessibility.

4. After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, and

plug in the electrical cords.

1.3 Cleaning the Gas Valve Vent Tube

1. Set the fryer power switch and the gas valve to the OFF position.

2. Carefully unscrew the vent tube from the gas valve. NOTE: The vent tube may be straightened

for ease in removal.

3. Pass a piece of ordinary binding wire (.052 inch diameter) through the tube to remove any

obstruction.

4. Remove the wire and blow through the tube to ensure it is clear.

5. Reinstall the tube and bend it so that the opening is pointing downward.

1.5 Measuring Flame Current

When the burner flame is properly adjusted, it will produce a current between 2.5 μA and 3.5 μA.
Flame current is measured by placing a microamp (not milliamp) meter in series with the sensing
wire on the ignitor. This is accomplished as follows:

1. Place the fryer power switch in the OFF position.

2. Disconnect the sensing wire from one of the burner ignitors and connect it to the positive lead of

the meter. Connect the negative lead of the meter to the terminal from which the sensing wire
was removed.

3. Place the fryer power switch in the ON position to light the burners. Wait at least one minute

after the frypot temperature reaches 200°F (93°C) before checking the reading. NOTE: The
closer the unit is to normal operating temperature, the more accurate the reading will be.

1.6 Replacing Fryer Components

1.6.1 Replacing the Controller or the Controller Wiring Harness

1. Disconnect the fryer from the electrical supply.

2. Remove the two screws in the upper corners of the control panel and swing the panel open from

the top, allowing it to rest on its hinge tabs.

3. Disconnect the wiring harness from the back of the controller and, if replacing the harness,

disconnect it from the interface board.

4. Disconnect the ground wire from the controller, and remove the controller by lifting it from the

hinge slots in the control panel frame.

5. Reverse the procedure to install a new controller or wiring harness. NOTE: Ensure that the fer-

rite bead (black ring) in the harness is at the controller end.

1.6.2 Replacing the Temperature Probe or High-Limit Thermostat

1. Disconnect the fryer from the electrical supply.

2. Drain cooking oil below the level of the probe or thermostat.

3. Remove the screws from the upper corners of the control panel and swing the panel open from
the top, allowing it to rest on its hinge tabs.

4. Unplug the controller wiring harness from the back of the controller.

5. Remove the controller by lifting it from the hinge slots in the control panel frame.

21. Insert the burners (9) into the rails to ensure the rail spacing and alignment are correct. The

burner should slide freely into and out of the rails. The upper rail can be bent slightly to increase
or decrease tension on the burner, and the edges of the slot can be closed or opened slightly to
best fit the burner frame.

22. Carefully wrap a strip of burner insulation (8) tightly around the rear and sides of the burner

frame (9), with the glass-tape side of the strip on the outside. Do not use duct tape or adhesive
to secure the strip to the burner frame.

23. Align the burner to the burner rails while maintaining tension on the insulation strip. Insert the

burner at a slight angle and begin pushing the burner slowly into the rails until it contacts the
rear combustion chamber. The fit should be snug, but not excessively tight.

24. Verify that the burners are flush with the front edge of the burner rails. Remove the excess

burner insulation by cutting with a knife or diagonal pliers. Do not try to tear the insulation!

25. Insert the upper front insulation (10) into its retainer (11), making sure that the holes in each

piece are aligned with one another. Install the assembly with the insulation side toward the
frypot and secure with ¼-20 washer-nuts. Do not over tighten.

26. Place a washer on each of the four lower studs on the front of the frypot. Install the lower inner

front insulation (12) with the rectangular openings toward the drain valve nipple. Install the
lower inner front insulation retainer(s) (13).

NOTE: Full vat units have a two-piece insulation retainer. Dual vat units have a one-piece
retainer.

27. If necessary, replace the sight-glasses and insulation (14).

28. Place one washer and one 1.888-inch spacer (15) on each stud.

NOTE: There are three different sizes of spacers. Verify the size to ensure the correct spacers
are installed.

29. Insert the front lower insulation (16) into the front lower insulation retainer(s) (17) and install

assembly on frypot. Secure with ¼-20 washer-nuts. If frypot uses two retainers, connect them
together with two ¼” self-tapping screws.

NOTE: Full vat units have a two-piece insulation retainer and two pieces of insulation. Dual
vat units have one-piece components.

30. Return to the rear of the frypot and fully tighten all washer-nuts.

31. Remove and replace the plenum gaskets (18).

32. Place a 0.938-inch spacer (19) on the plenum-mounting studs, and mount the plenum (20). En-

sure the gaskets are clear of the burner tubes by pulling the plenum back slightly. Place a washer
on each stud and secure plenum with ¼-20 locknuts.

1-19

33. Install the upper oil-zone insulation (21) by pressing it under the upper combustion chamber
metalwork. Secure the insulation with the bracket (22) and ¼” self-tapping screws.

34. Install the upper burner rail blanket insulation (23). Position any excess insulation toward the
top of the frypot. Avoid overhang past the bottom of the upper burner rail. Overhang in this
area will make future burner replacement more difficult.

35. Cover the insulation with the insulation retainer (24), and secure with ¼” self-tapping screws.

36. Reinstall probes, drain valves, high-limit thermostats and other pipefittings using Loctite

®

PST56765 sealant or equivalent on their threads.

1.7 Troubleshooting and Problem Isolation

Because it is not feasible to attempt to include in this manual every conceivable problem or trouble
condition that might be encountered, this section is intended to provide technicians with a general
knowledge of the broad problem categories associated with this equipment, and the probable causes
of each. With this knowledge, the technician should be able to isolate and correct any problem
encountered.

Problems you are likely to encounter can be grouped into seven broad categories:

1. Ignition failures

2. Improper burner functioning

3. Improper temperature control

4. Computer-related problems

5. Filtration problems

6. Leakage

7. Basket lift malfunctions.

The probable causes of each category are discussed in the following sections. A series of Trouble­shooting Guides is also included at the end of the chapter to assist in identifying some of the more
common problems.

1.7.1 Ignition Failures

Ignition failure occurs when the ignition module fails to sense a flame within the 4-second time de­lay period and locks out. When this happens, the module sends 24 VAC through the interface board
alarm circuit to the controller/computer.

Analog controllers indicate ignition failure by illuminating the heat light and trouble light
simultaneously. Digital, Computer Magic III, and Basket Lift Timer controls display “

H E L p.”

The three primary reasons for ignition failure, listed in order of probability, are:

1. Problems related to the gas and/or electrical power supplies

2. Problems related to the electronic circuits

3. Problems related to the gas valve.

1-20

PROBLEMS RELATED TO THE GAS AND/OR ELECTRICAL POWER SUPPLIES

The main indicators of this are that an entire battery of fryers fails to light and/or there are no
indicator lights illuminated on the fryer experiencing ignition failure. Verify that the quick
disconnect fitting is properly connected, the fryer is plugged in, the main gas supply valve is open,
and the circuit breaker for the fryer electrical supply is not tripped.

PROBLEMS RELATED TO THE ELECTRONIC CIRCUITS

If gas and electrical power are being supplied to the fryer, the next most likely cause of ignition fail­ure is a problem in the 24 VAC circuit. If the fryer is equipped with a built-in filtration system, first
verify that the drain valve is fully closed. (The valve is attached to a microswitch that must be
closed for power to reach the gas valve. Often, although the valve handle appears to be in the closed
position, the microswitch is still open.) If the valve is fully closed, or the fryer does not have a built­in filtration system, refer to the troubleshooting guides

TROUBLESHOOTING THE 24 VAC CIRCUIT.

Some typical causes of ignition failure in this category include a defective sensing wire in the ignitor
assembly, a defective module, a defective ignition wire, and a defective ignitor.

Occasionally you may encounter an ignition failure situation in which all components appear to be
serviceable and the microamp reading is within specification, but the unit nevertheless goes into ig­nition failure during operation. The probable cause in this case is an intermittent failure of an igni­tion module. When the unit is opened up for troubleshooting, the module cools down enough to op­erate correctly, but when the unit is again closed up and placed back into service the module heats
up and fails.

PROBLEMS RELATED TO THE GAS VALVE

If the problem is not in the 24 VAC circuit, it is most likely in the gas valve itself, but before replac­ing the gas valve refer to TROUBLE SHOOTING THE GAS VALVE.

1.7.2 Improper Burner Functioning

With problems in this category, the burner ignites but exhibits abnormal characteristics such as
“popping,” dark spots on the burner ceramics, fluctuating flame intensity, and flames shooting out of
the flue.

“Popping” indicates delayed ignition. In this condition, the main gas valve is opening but the burner
is not immediately lighting. When ignition does take place, the excess gas “explodes” into flame,
rather than smoothly igniting.

The primary causes of popping are:

● Incorrect or fluctuating gas pressure

● A defective or incorrectly adjusted combustion air blower

● Inadequate make-up air

● Heat damage to the controller or ignition module

● A cracked ignitor or broken ignition wire

● A defective ignition module

● Cracked burner tile (this typically causes a very loud pop)

1-21

O

O

If popping occurs only during peak operating hours, the problem may be incorrect or fluctuating gas
pressure. Verify that the incoming gas pressure (pressure to the gas valve) is in accordance with the
appropriate table below, and that the pressure remains constant throughout all hours of usage. Refer
to Check Burner Manifold Pressure in the section of 1.4 for the procedure for checking the
pressure of gas supplied to the burner.

If popping is consistent during all hours of operation, the most likely cause is an insufficient air supply.
Check for “negative pressure” conditions in the kitchen area. If air is flowing into the kitchen area, this
indicates that more air is being exhausted than is being replenished and the burners may be starved for air.

If the fryer’s gas and air supplies are okay, the problem is most likely with one of the electrical
components. Examine the ignition module and controller for signs of melting/distortion and/or
discoloration due to excessive heat build-up in the fryer. (This condition usually indicates improper flue
performance.) A melted or distorted ignition module is automatically suspect and should be replaced,
but unless the condition causing excessive heat is corrected, the problem is likely to recur.

Verify that the ignition wire is tightly connected at both ends and free of obvious signs of damage.
Again, if damage is due to excessive heat in the fryer, that problem must also be corrected.

Check for proper operation by disconnecting the wire from the ignitor (spark plug), inserting the tip of a
screw driver into the terminal, and holding it near the frame of the fryer as the power switch is placed in
the ON position. A strong, blue spark should be generated for at least 4 seconds.

AND NOT THE BLADE. THE SPARKING CHARGE IS APPROXIMATELY 25,000

VOLTS.

Examine the ignitor (spark plug) for any signs of cracking. A cracked ignitor must be replaced.

1-22

If all other causes have been ruled out, examine the burner tiles for any signs of cracking. If cracks are
found, the burner must be replaced.

Fluctuating flame intensity is normally caused by either improper or fluctuating incoming gas pressure,
but may also be the result of variations in the kitchen atmosphere. Verify incoming gas pressure in the
same way as for “popping,” discussed in the preceding paragraphs. Variations in the kitchen
atmosphere are usually caused by air conditioning and/or ventilation units. As they start and stop, the
pressure in the kitchen may change from positive or neutral to negative, or vice versa. They may also
cause changes in airflow patterns that may affect flame intensity.

Dark spots on the burner tiles are the result of an improper air/gas mixture. Adjust the combustion air
blower to reduce the amount of air in the mixture to correct this problem.

Flames shooting out of the flue are usually an indication of negative pressure in the kitchen. Air is
being sucked out of the burner enclosure and the flames are literally following the air. If negative
pressure is not the cause, check for high burner manifold gas pressure in accordance with the procedure
in Section 1.4.

An excessively noisy burner, especially with flames visible above the flue opening, may indicate that
the gas pressure is too high, or it may simply be that the gas valve vent tube is blocked. If the incoming
gas pressure is correct and the vent tube is unobstructed, the gas valve regulator is probably defective.

Occasionally a burner may apparently be operating correctly, but nevertheless the fryer has a slow re-
covery rate (the length of time required for the fryer to increase the oil temperature from 275ºF to 325ºF
(135ºC to 163ºC)). The primary causes of this are an over-filled vat, a dirty or out-of-adjustment com­bustion air blower, low burner manifold pressure, and/or damaged burner tiles. Adding oil to the frypot
during the recovery process will also cause a slow recovery rate. If these causes are ruled out, the prob­able cause is a misadjusted gas valve regulator. Refer to the Check Burner Manifold Pressure proce­dure Section 1.4.

1.7.3 Improper Temperature Control

Temperature control, including the melt cycle, is a function of several interrelated components, each of
which must operate correctly. The principle component is the temperature probe. Other components
include the interface board, the controller itself, and the ignition module.

Improper temperature control problems can be categorized into melt cycle problems and failure to con­trol at setpoint problems.

MELT CYCLE PROBLEMS

In fryers equipped with analog controls, the melt cycle must be initiated by pressing the melt cycle
switch. With all other controllers, initiation of the melt cycle is automatic. Problems may be with
the controller itself, the temperature probe, or a malfunctioning heat relay on the interface board.

1-23

FAILURE TO CONTROL AT SETPOINT

Problems in this category may be with the temperature probe, the interface board, or the controller.

1.7.4 Computer-Related Problems

COMPUTER MAGIC III FEATURES

SENSITIVITY OR “STRETCH AND SHRINK TIME”

Sensitivity or stretch time is a programmable feature, patented by Frymaster, which increases or decreases
the cooking time countdown based on variations in the oil temperature from the set point.

The sensitivity for each product button has ten settings (0 through 9). A zero sensitivity setting
will disable the feature (no change in cooking time), while a nine will provide the highest sensi­tivity or most change. The correct sensitivity for any product is based on the product, its density,
the set point temperature, and the customer’s own requirements.

RECOVERY TIME

Recovery time is a method of measuring a fryer’s performance. Put simply, it is the time required for the
fryer to increase the oil temperature from 275ºF to 325ºF (135ºC to 163ºC). This range is used as a stan­dard since ambient kitchen temperatures can effect the test if lower ranges are used.

The Computer Magic III performs the recovery test each time the fryer warms up. An operator
can view the results of the test any time the fryer is above the 325ºF (163ºC) point by pressing

the button and entering the code 1652. The test results will be displayed in the computer’s
LED panel in minutes and seconds. The maximum acceptable recovery time for the H50 Series
of fryers is two minutes and twenty-five seconds.

COMMON COMPUTER COMPLAINTS

Most problems concerning computers have to do with programming them. There are four common
complaints. The complaints, their causes, and corrective actions are:

1. Fryer constantly displays “HI.”

Cause: Setpoint incorrect or missing.

Corrective Action: Press

1650, enter the correct setpoint using keypad, and then press to lock in

the setpoint.

2. Temperature is displayed in Celsius.
Cause: Computer is programmed to display in Celsius.

Corrective Action: Press

1658.

3. Temperature is constantly displayed.
Cause: Computer is programmed for constant temperature display.

Corrective Action: Press

165L.

4. Computer times down too slowly or too quickly.

1.7.5 Filtration Problems

The majority of filtration problems arise from operator error. One of the most common errors is
placing the filter paper on the bottom of the filter pan rather than over the filter screen.

Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation
of the filter paper, including that the correct size is being used. While you are checking the filter
paper, verify that the O-ring on the bottom of the filter pan is present and in good condition. A
missing or worn O-ring will allow the pump to suck air and decrease its efficiency.

If the pump motor overheats, its thermal overload will trip and the motor will not start until it is
reset. If the pump motor does not start, press the red reset switch located on the rear of the motor. If
the pump then starts, something caused the motor to overheat. It may just be that several frypots
were being filtered one after the other and the pump got hot. Letting the pump cool down for at least
a half-hour is all that is required in this case. More often, the pump overheated for one of the
following reasons:

● Shortening was solidified in the pan or filter lines.

● The operator attempted to filter oil or shortening that was not heated. Cold oil and shorten-

ing are thicker and cause the pump motor to work harder and overheat.

If the motor hums but the pump does not rotate, there is a blockage in the pump. Incorrectly sized or
installed paper will allow food particles and sediment to pass through the filter pan and into the
pump. When sediment enters the pump, the gears can bind up causing the motor to overload, again
tripping the thermal overload. Solidified shortening in the pump will also cause it to seize, with the
same result.

A pump seized by debris or hard shortening can usually be freed by manually moving the gears with
a screwdriver or other instrument as illustrated below. Make sure power to the pump motor is off

before trying this.

1. Disconnect power to the filter system.

2. Remove the input plumbing from the pump.

3. Use a screwdriver to manually turn the gears.

● Turning the pump gears backwards will release a

hard particle and allow its removal.

● Turning the pump gears forward will push softer

Incorrectly sized or installed paper will also allow food particles and sediment to pass through and
clog the suction tube on the bottom of the filter carriage. Particles large enough to block the suction
tube may indicate that the crumb tray is not being used.

1-25

Pan blockage can also occur if shortening is left in the pan and allowed to solidify. The heater strip
on the suction tube is designed to prevent solidification of residual shortening left in the tube. It will
not melt or prevent solidification of shortening in the pan.

Blockage removal can be accomplished by forcing the item out with an auger or drain snake. Never
attempt to use compressed air or other pressurized gases to force out the blockage.

Possible problems with the Power Shower include clogged openings, shortening solidified in the
tubes, missing clean-out plugs, and missing or worn O-rings. Cleaning the unit and replacing
missing plugs and missing or worn O-rings will correct these problems.

The electronics of the Filter Magic and FootPrint III systems are simple and straightforward.
Microswitches, attached to handles for each vat and wired in parallel, provide the 24 VAC required
to activate the pump relay coil when the handles are moved to the ON position. The activated pump
relay coil pulls in the pump motor switch, supplying power to the pump motor.

The oil return line heater tapes in the Filter Magic system are wired directly into the line VAC
source and remain energized as long as the unit is plugged in. The filter pan suction tube heater
tape, however, is wired into the 24 VAC circuit. The suction tube tape is activated only when the
filter pan is positioned all the way to the rear of the cabinet, allowing a pair of “bullet” contactors
mounted on the pan to touch a corresponding pair of contactors mounted on the cabinet frame.

For FootPrint III systems built before August 1997, all heater tapes are wired directly into the line
VAC source. They remain energized as long as the unit is plugged in. In systems built in August
1997 and later, oil return line heater tapes have been eliminated. In these units, the only heater tape
used is on the suction tube and pump. This tape is still wired directly into the line voltage. A pair of
vacuum-breaking solenoids is wired into the 24 VAC circuit.

In units built from August 1997 onward, the oil return system allows oil to drain back to the filter
pan when the filter system is turned off, eliminating the need for most heated oil return components.

1-26

For a short time, one-piece, welded oil return manifolds were used. The one-piece manifolds have
been replaced with Dormont stainless steel flexlines and nipples and are no longer available.

A solenoid vent valve is mounted on the left end of the front oil return assembly. It prevents
vacuum-lock of the system as oil drains back to the filter pan when the unit is turned off. The
solenoid valve is connected to the square drain sub-system by a clear ⅜” O.D. Teflon tube and
threaded fittings. Stainless steel Dormont flexlines connect the manifolds to the valves. Standard
½” X ½” X 90º black metal street elbows are used to make the connections.

A 22-inch Dormont stainless steel flexline, running above the filter assembly, connects the front oil
return assembly to the rear manifold.

Filter Base Assembly and Pump Sub-System

Casters have not been used on filter base assemblies built since August 1997. When the casters were
eliminated from the filter base assembly, the assembly was redesigned to prevent it from being taken
out of the cabinet without removing a set of machine screws and nuts.

A new Teflon hose with a braided stainless steel covering connects the pump to the rear manifold
and replaces the heated hose running from the pump discharge under the unit to the Power Shower
plumbing. The new hose is fitted with a 90º swivel at the manifold end and a straight swivel at the
pump end to prevent kinking.

The pump plumbing features a solenoid valve at the pump discharge, a ¼” I.D. Dormont stainless
steel flexline that connects the solenoid valve to the pump inlet fittings, and miscellaneous standard
black metal fittings for connections. This design allows oil to bypass the pump as it drains from the
oil return lines back into the filter pan when the system is turned off. Bypassing the pump expedites
draining of the lines. The pump solenoid leads are connected to Pins 7 and 9 of the upper 9-pin plug
assembly of the filter box.

Filter Wiring Box

The original-design 5-lead cable connecting the filter assembly to the filter wiring box has been
replaced with a new, universal 7-lead cable to accommodate the solenoid mounted on the front

1-27

manifold. The two new leads have a separate connector for attachment to the solenoid. When a
filter cable is ordered for either filtration system configuration (original or redesigned), the new
7-wire cable will be sent. The two extra wires and connector will not interfere with the original
filtration system or its operation.

Verifying Solenoid Operation

Proper operation of the 24VAC manifold and pump solenoids can be verified by removing the pump
motor lead from terminal 4 of the pump motor relay in the filter wiring box and then activating the
oil return lever. Proper solenoid operation will be evidenced by an audible “click” or vibration of
both the pump solenoid and the manifold solenoid.

1.7.6 Leakage

Leakage of the frypot is usually due to improperly sealed high limit thermostats, temperature probes,
and drain fittings. When installed or replaced, each of these components must be sealed with
Loctite

®

PST56765 sealant or equivalent to prevent leakage and torqued to 180 inch-pounds. In
very rare cases, a leak may develop along one of the welded edges of the frypot. When this occurs,
the frypot must be replaced.

If the sides and/or ends of the frypot are coated with oil, the most likely cause is spillage over the top
of the frypot rather than leakage.

The clamps, which hold the drain tube sections together, may loosen over time as the tubes expand
and contract with heating and cooling during use. If the section of drain tube connected to the drain
valve is removed for whatever reason, make sure that its grommet is in good condition and properly
fitted around the nipple of the drain when it is reinstalled. Also, ensure that the drain tube runs
downward from the drain along its whole length and has no low points, where oil may accumulate.

1.7.7 Basket Lift Malfunctions

H50 Series fryers may optionally be equipped with automatic basket lifts to ensure uniform cooking
times. Basket lifts will always come in pairs, although each operates independently of the other.

Depending upon the specific model, date of manufacture, and customer specifications, an H50 fryer
may be equipped with a bell crank style basket lift, or a “modular” basket lift.

A modular basket lift (illustrated below) consists of a toothed rod to which the basket lift arm is
attached, a reversible-drive gear motor, and a pair of roller-activated microswitches. The gear motor
engages the teeth in the rod, moving it up or down depending upon the direction of rotation of the
motor. Microswitches at the upper and lower limits of movement stop the motor when the basket is
in the full up or full down position.

Timing circuitry in the controller initiates and stops basket lift operation depending upon the
variables programmed by the operator. When the product button is pressed, the timing circuitry
activates a coil in the basket lift relay to supply power to the lower microswitch. The microswitches
stop the motor at the lift’s upper and lower travel limits and reverse the direction of current flow,
thus reversing the motor direction.

1-28

100/120V Modular Basket Lift Assembly

P/N 806-8530SP (TYPICAL)

1-29

A bell crank style basket lift consists of a cam and bell
crank that are connected to the basket lift arm by a flat metal
link. The cam is attached to a drive motor. The motor ro­tates the cam, thus raising or lowering the lift arm linked to
the bell crank. A roller-activated microswitch is used to limit
travel. When the roller in the microswitch is in contact with
the cam, the motor is energized. As the cam rotates, the mi­croswitch roller eventually loses contact with the cam and
the circuit is broken, de-energizing the motor.

Timing circuitry in the controller initiates and stops basket
lift operation depending upon the variables programmed by
the operator. When the product button is pressed, the timing
circuitry activates a coil in the basket lift relay to supply

power to the motor. The microswitch stops the motor at the
lift’s lower travel limit and the switch contacts are reversed. At the end of the programmed cooking
time, the timing circuit activates the coil once more and the lift rises until the microswitch again
loses contact with the cam, opening the circuit and stopping the motor.

Problems with either basket lift design can be grouped into three categories:

• Binding/jamming problems

• Motor and gear problems

• Electronics problems

BINDING/JAMMING PROBLEMS

Noisy, jerky or erratic movement of the lifts is usually due to lack of lubrication of the rods and their
bushings. Apply a light coat of Lubriplate® or similar lightweight white grease to the rod and
bushings to correct the problem.

With the modular basket lift, another possible cause of binding is improper positioning of the motor,
which prevents the gear from correctly engaging the teeth in the rod. To correct the problem, loosen
the screws that hold the motor in place and move it forward or backward until the rod has just
enough slack to be rotated slightly.

MOTOR AND GEAR PROBLEMS

With the modular basket lift, the most likely problem to be encountered in this category is erratic
motion of the lift due to a worn drive gear. Failure to keep the lift rod and bushings properly
lubricated will cause unnecessary wear of the gear. The problem is corrected by replacing the worn
gear.

If the lift cycles correctly but fails to remain in the up position (i.e., goes up, but then slowly settles
back down into the frypot), the problem is a failed motor brake. A failed motor brake cannot be
repaired and requires replacement of the motor itself.

1-30

If power is reaching the motor but the motor fails to run, the motor is burned out and must be
replaced.

ELECTRONICS PROBLEMS

Within this category are problems associated with the relays, microswitches, capacitors, resistors,
interface board, wiring, and controls. The most common problem in this category is a lift that
continuously travels up and down. This is usually caused by a microswitch that is out of adjustment.

Troubleshooting the electronics of either type basket lift is simply a process of verifying current
flow through the individual components up to and including the motor. Using a multimeter set to
the 250 VAC range, check the connections on both sides of the component for the presence of the
applied line voltage. The accompanying simplified wiring diagrams identify the components and
wiring connection points.

1.7.8 Interpretation of Digital Controller Lights

normally.

● If the oil temperature is above 180ºF (82ºC) and the heat light continues to cycle as if in the

melt cycle, this may indicate a defective probe circuit or low incoming 12VAC to the
controller.

● If the fryer oil temperature is above 180ºF (82ºC) and below the setpoint temperature, the

lights indicate the unit is operating properly.

● If the oil temperature is above the temperature set on the control knob and the heat light

remains lit, this may indicate a defective probe circuit.

● If the fryer oil temperature is below 410ºF (210ºC), the lights indicate one of the following:
a. The probe circuit is defective, or
b. There is a connection problem on pins 2 or 10 on the 15-pin wiring harness.

● If the fryer oil temperature is above 410ºF (210ºC), the lights indicate a run-away heating
circuit.

1.8 Troubleshooting Guide

The troubleshooting guide that follows is intended to assist service technicians in quickly isolating
the probable causes of equipment malfunctions. An additional set of operator troubleshooting guides
is contained in Chapter 6 of the H50 Series Installation and Operation Manual (P/N 819-5000). It is
suggested that service technicians thoroughly familiarize themselves with both sets.

NOTES: Items 5, 6, and 7 are components of Items 3 and 4. In CE units, they replace the rotating air shutter
that is standard on 230V Blowers 106-3000SP and 106-3001SP (Items 3 and 4).

Blower Motor Cover P/N 816-0054 and Screw P/N 809-0938 are components of Items 1 through 4.
For Full Vat units, use Blower Assembly 106-2994SP (Non-CE) or 106-3000SP (CE). (Left Assembly.)

Some earlier CE units were built with blowers having housings 1.54 inches (3.91 cm) wide. Current production
CE-units are built with blowers having housings 2.71 inches (6.88 cm) wide. When ordering replacements for CE
units, the width of the blower housing must be verified to ensure the correct blower is provided.

CE units built before June 1999 were equipped with a blower shield that completely covered the blower
assemblies. This shield is no longer required and may be removed. The component parts of the shield are no
longer available for replacement.
