BIPH52/55-MPH52/55 SERIES GAS FRYERS

CHAPTER 1: SERVICE PROCEDURES

1.1 Functional Description

BIPH52/55 and MPH52/55 Series gas 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 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 24 VAC gas valve systems, and all are configured with electronic ignition.

1.1.1 The Electronic Ignition System

Inside the Ignition Module

An ignition module mounted in the component box (located behind the control panel) is connected to an ignitor assembly at the burner. The ignition module performs four important functions: it provides fuse

Out to Gas Valve

To Al arm

protection for the 24-volt circuit, provides an ignition spark, supplies voltage to the gas valve, and proofs the

25 V +

burner flame. The module contains a 4-second time delay circuit and a coil that activates the gas valve. Three types 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

GND

Coil

current production full-vat fryers. 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 the other leg of the heat relay coils, which then close electronic switches in the 24 VAC circuit to

1-1

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.

1.1.2 Interface Board

All fryers in this series have an interface board located in the component box 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. This standard interface board is also used in a number of fryer types besides the BIPH52/55 and MPH52/55 Series. The information contained in this section applies to

BIPH52/55 and MPH52/55 Series applications ONLY.

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.

LEDs (labeled D1 through D7) are arrayed around the board to assist in troubleshooting.

1.1.3 THERMOSTATS

BIPH52/55 and MPH52/55 Series gas fryers have temperature probes located on the front centerline of each frypot (dual-vat frypots have two probes, one in each vat). In this type of 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.

BIPH52/55 and MPH52/55 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 oil may cause spilling or splattering of the hot liquid.

Follow the draining instructions in Chapter 4 of the BIPH52/55-MPH52/55 Installation

and Operation manual (P/N 819-6087) 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.

1-4

2. Remove any attached restraining devices and relocate the fryer for service accessibility.

3. After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, and plug in the electrical cords. NOTE: To ensure the safe and efficient operation of the fryer

and hood, the electrical plug for the 120-volt line, which powers the hood, must be fully engaged and locked in its pin and sleeve socket.

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 of 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.

1.4 Checking the Burner Manifold Gas Pressure

1. On non-CE fryers only ensure that the gas valve knob is in the OFF position.

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.

18. Place one 1.625-inch tubular spacer (5) on each of the flue assembly (upper) studs at the rear of the frypot. NOTE: There are three different sizes of spacers. Verify the size to ensure the correct spacers are installed.

19. Press the flue assembly (6) over the burner rails. It may be necessary to use a rubber mallet or screwdriver to align the components. Use four ¼”-20 washer nuts to secure the flue assembly. Do not tighten the retainer nuts at this point. They should be finger-tight only. NOTE: The flue edge will cover one to two inches of the lower insulation.

20. Install the lower rear combustion chamber back(s) and retainer(s) (7) with the flanged edge(s) against the flue. Secure with ¼”-20 washer nuts. NOTE: Full-vat units have two-piece backs and four retainers. Dual-vat units come with one-piece backs and only two retainers.

21. Insert the burners (9) into the rails to ensure the rail spacing and alignments 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.

1-22

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

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 six categories:

1. Ignition failure

2. Improper burner function

3. Improper temperature control

4. Computer malfunctions

5. Filtration malfunctions

6. Leakage

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 solving some of the more common problems.

1.7.1 Ignition Failure

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 computer.

M2000 computers display “IGNITION FAILURE.”

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

1. Gas and/or electrical power supplies

2. Electronic circuits

3. Gas valve.

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 with connector twisted and locked, 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. 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

1-25

valve handle appears to be in the closed position, the microswitch is still open). If the valve is fully closed, refer to Section 1.8.1, 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; however, 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. Before replacing the gas valve, refer to Section 1.8.2 TROUBLESHOOTING THE GAS VALVE.

1.7.2 Improper Burner Function

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

• Defective or incorrectly adjusted combustion air blower

• Inadequate make-up air

• Heat-damaged controller or ignition module

• Cracked ignitor or broken ignition wire

• Defective ignition module

• Cracked burner tile (typically causes a very loud pop).

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 CE or Non-CE Standard found in Section 2.3 of the BIPH52/55-MPH52/55 Series Gas Fryer Installation and Operation Manual (part number 819-6087), and that the pressure remains constant throughout all hours of usage. Refer to Section 1.4, Checking the Burner Manifold Gas Pressure in this manual 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

1-26

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; however, 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. With the insulated handle of the screwdriver, hold the shaft 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.

DANGER

Make sure you are holding the insulated handle of the screwdriver 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.

If all other causes have been ruled out, examine the burner tiles for any signs of cracking. If cracking is 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 starting and stopping during the day. 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 procedures 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 recovery rate (the length of time required for the fryer to increase the oil temperature from 270ºF to

1-27

320ºF (132ºC to 160ºC)). The primary causes of this include an over-filled frypot, 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 Section 1.4, Checking the Burner Manifold Gas Pressure, for the gas valve adjustment procedure.

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 M2000 computers, initiation of the melt cycle is automatic. Problems may originate from the controller itself, the temperature probe, or a malfunctioning heat relay on the interface board.

FAILURE TO CONTROL AT SETPOINT

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

1.7.4 Computer Malfunctions

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 270ºF to 320ºF (132ºC to 160ºC). This range is used as a standard since ambient kitchen temperatures can affect the test if lower ranges are used.

The M2000 computer 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 BIPH52/55-MPH52/55 Series gas fryers is two minutes and twenty-five seconds.

1-28

COMMON COMPUTER COMPLAINTS

Most problems concerning computers have to do with programming them. There are two common complaints:

1. Fryer constantly displays “HI.”

Cause: Setpoint is incorrect or missing.

Corrective Action: Check setpoint and refer to the M2000 computer manual for instructions to

adjust the setpoint.

2. Temperature is displayed in Celsius. Cause: Computer is programmed to display in Celsius. Corrective Action: Turn the computer off then press 1658.

1.7.5 Filtration Malfunctions

The majority of filtration problems arise from operator error. One of the most common errors is placing the filter pad 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 pad, including that the correct size is being used. While you are checking the filter pad, verify that the O-rings on the filter pan suction tube are present and in good condition. Missing or worn O-rings 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 front of the motor. If the pump then starts, something caused the motor to overheat. It may be just that several frypots in a large battery of fryers were being filtered one after the other and the pump became 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 that remained in the pan after previous filtering solidified in the suction tube

recess in the bottom of the pan or the suction tube, itself. Adding hot oil to the pan and waiting a few minutes will usually correct this problem. A flexible wire can be used to clean out the suction tube and the recess in the bottom of the pan. NEVER use compressed air to blow solidified shortening out of the suction tube!

• The operator attempted to filter oil that was not heated. Cold oil is thicker and causes 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 and cause the motor to overload, tripping the thermal overload. Solidified shortening in the pump will also cause it to seize, with similar results.

1-29

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 on the following page. 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.

Up for reverse

• Turning the pump gears backwards will

removal.

• Turning the pump gears forward will push

softer objects and solid shortening through the pump and allow free movement of the gears.

Filter pads that are installed incorrectly will also allow food particles and sediment to pass through and clog the suction tube recess on the bottom of the filter pan or the suction tube, itself. Particles large enough to block the suction tube recess or the suction tube may indicate that the crumb tray is not being used.

The electronics of the FootPrint PRO system, illustrated in the schematic below, are simple and straightforward.

solenoid and the manifold solenoid.

1.7.6 Leakage

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

1-30

Loctite® PST56765 sealant or equivalent to prevent leakage. 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 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 on the rubber boots that hold the drain tube sections together may loosen over time as the tubes expand and contract with heating and cooling during use. Also, the boot itself may be damaged. If the section of drain tube connected to the drain valve is removed for any reason, ensure that its rubber and clamps are in good condition and properly fitted around the drain tube when it is reinstalled. Also, check to ensure that the drain tube runs downward from the drain along its whole length and has no low points where oil may accumulate.

1.8 Troubleshooting Guides

The troubleshooting guides on the following pages are intended to assist service technicians in quickly isolating the probable causes of equipment malfunctions by following a logical, systematic process. An additional set of operator troubleshooting guides is contained in Chapter 6 of the BIPH52/55-MPH52/55 Series Installation and Operation Manual (P/N 819-6087). It is suggested that service technicians thoroughly familiarize themselves with both sets.

1.8.1 Troubleshooting the 24 VAC Circuit

Prior to checking for problems associated with the 24 VAC circuit, ensure that the unit is connected to a power supply, the drain valve is fully closed, and the controller is on and is calling for heat (green dot appears under heat indicator and display toggles between LOW and TEMP).

NOTE: All voltage measurements must be made within 4 seconds of the unit calling for heat. If unit does not fire within 4 seconds, ignition modules will lock out and controller must be turned off, then on to reset.

The following processes will assist you in troubleshooting the 24 VAC circuit and ruling it out as a probable cause:

• 24 VAC is not

present on the interface board J3 pin 9 (LED 5 (GV)) and, on dual units, on

J1 pin 9 (LED 1 (GV)).

1. If LED 3 is not continually lit, the probable causes are a failed 24 VAC transformer or failed

wiring between transformer and interface board.

2. If LED 3 is continually lit, check the right PWR terminal (LED 4) for 24 VAC. On dual

units, also check the left PWR terminal (LED 2) for 24 VAC. Verify that the F2 fuse is not blown.

a. If 24 VAC is not present, the probable cause is a failed interface board, blown fuse or a

defective heat relay.

b. If 24 VAC is present, check for 24 VAC on V1S (or V1D and V2D, if dual unit).

1-31

i. If 24 VAC is not present, check the fuses. If they are good, the probable causes are

failed ignition module(s) or a failed interface board. Replace the questionable ignition module with one known to be good to isolate the cause.

ii. If 24 VAC is present, the probable cause is a failed interface board.

• 24 VAC is

present on interface board J3 pin 9 (LED 5 (GV)) and, on dual units, on J1 pin 9

(LED 1 (GV)).

1. If 24 VAC is not present across the gas valve main coil (MV terminals), probable causes are

an open high-limit thermostat or a failed wire between the interface board and gas valve. Be sure to check both valves on dual units. It may also be caused by a failed drain safety switch.

Check continuity of high-limit thermostat and drain safety switch. If both are zero, problem is in wiring.

2. If 24 VAC is present across the gas valve main coil (MV terminals), the 24 VAC circuit is

okay and the problem may be with the gas valve. Be sure to check both valves on dual units.

1.8.2 Troubleshooting the Gas Valve

Prior to checking for problems associated with the gas valve, ensure that the unit is calling for heat. Also, for non-CE units, verify that the gas valve is in the ON position.

The following processes will assist you in troubleshooting the gas valve and ruling it out as a probable cause:

• If 24 VAC is not present across gas valve main coil, the probable cause is the 24 VAC circuit.

Refer to the 24 VAC circuit troubleshooting guide.

• If 24 VAC is present across gas valve main coil, check the incoming gas pressure and compare

to the tables in Section 2.3 of the Installation and Operation manual.

1. If incoming gas pressure is not correct, the probable cause is a problem with the gas supply

to fryer.

2. If incoming gas pressure is correct, check the outgoing gas pressure and compare it to the

tables on Page 2-4 of the Installation and Operation manual. a. If outgoing gas pressure is not correct, the probable cause is an improperly adjusted or

failed gas valve. Adjust the valve by following the procedure “Check Burner Manifold Pressure” in Section 1.4 of this manual.

If the valve cannot be adjusted, replace it.

b. If outgoing gas pressure is correct, the gas valve is okay.

1.8.3 Troubleshooting the Temperature Probe

CAUTION Disconnect the M2000 computer before testing temperature probe resistances to avoid invalid readings

Prior to checking for problems associated with the temperature probe, inspect the probe body for damage while it is still in the frypot. Remove and replace the probe if it is bent, dented, or cracked. Also, inspect leads for fraying, burning, breaks, and/or kinks. If found, replace the probe.

The following processes will assist you in troubleshooting the gas valve and ruling it out as a probable cause:

Before testing the probe, determine the temperature the cooking oil using another thermometer or pyrometer placed at the tip of the questionable probe.

• If resistance through J3 pins 2 and 6 (J1 pins 2 and 6 for left side of dual unit) is not

approximately equal to that given in the Probe Resistance Chart for the corresponding temperature, the probe has failed and must be replaced.

1-35

• If resistance through J3 pins 2 and 6 (J1 pins 2 and 6 for left side of dual unit) is

approximately equal to that given in the Probe Resistance Chart for the corresponding temperature, measure the resistance through each of the previously tested pins to ground.

1. If resistance is not 5 mega-Ohms or greater in each pin, the probe has failed and must be

replaced.

2. If resistance is 5 mega-Ohms or greater in each pin, the probe is okay.
