SECTION 1. TROUBLESHOOTING
1-1. INTRODUCTION This section provides troubleshooting information in the form
of an easy to read table.
If a problem occurs during the first operation of a new fryer,
recheck the installation per the Installation Section of this
manual.
Before troubleshooting, always recheck the operation procedures per Section 3 of the Operator’s Manual.
1-2. SAFETY
Where information is of particular importance or safety related,
the words DANGER, WARNING , CAUTION, and NOTICE are
used. Their usage is described below .
SAFETY ALER T SYMBOL is used with DANGER,
W ARNING, or CAUTION which indicates a personal injury
type hazard.
NOTICE is used to highlight especially important information.
CAUTION used without the safety alert symbol indicates
a potentially hazardous situation which, if not avoided,
may result in pr operty damage.
CAUTION indicates a potentially hazardous situation
which, if not avoided, may result in minor or moderate
injury.
W ARNING indicates a potentially hazardous situation
which, if not avoided, could result in death or serious
injury .
DANGER INDICA TES AN IMMINENTL Y
HAZARDOUS SITUA TION WHICH, IF NOT
AVOIDED, WILL RESULT IN DEATH OR SERIOUS
INJURY.

SECTION 2. MAINTENANCE
2-1. INTRODUCTION This section provides checkout and replacement procedures, for
various parts of the fryer . Before replacing any parts, refer to the
Troubleshooting section to aid you in finding the cause of the
malfunction.
2-2. MAINTENANCE HINTS 1. A multimeter will help you to check the electric components.
2. When the manual refers to the circuit being closed, the
multimeter should read zero unless otherwise noted.
3. When the manual refers to the circuit being open, the
multimeter should read infinity .
Do not move the fryer with hot shortening in the frypot or
filter pan. Severe burns can result from splashing hot
shortening.
4. Remove weights from the frame to easily access rear of fryer.
2-3. PREVENTIVE To ensure a long life of the fryers and their components, regular
MAINTENANCE maintenance should be performed. Refer to the chart below .
Frequency Action
T wice Daily Filter Shortening (See Operator’ s Manual)
Monthly Check Dilution Box, Clean as needed
(See Cleaning the Dilution Box Section)
Annually Clean Blower Wheel (See Cleaning the
Blower Wheel Section)
Annually Lubricate Lid Rollers in back of fryer.
(See Lubricating Lid Rollers Section)

2-4. HIGH TEMPERATURE
LIMIT CONTROL This high temperature control is a safety , manual reset control,
which senses the temperature of the shortening. If the shortening
temperature exceeds 425°F (218°C), this switch opens
and shuts off the heat to the frypot. When the temperature of
the shortening drops to a safe operation limit, manually reset by
pressing the red reset button. The red reset button is located under
the control panel, in the front of the fryer . Once reset, the frypot
starts heating.
Before replacing a high temperature limit control, check to see
that its circuit is closed.
Checkout
The shortening temperature must be below 380°F
(193°C) to accurately perform this check.
1. Remove electrical power supplied to the fryer .
T o avoid electrical shock or pr operty damage, move the
Power switch to OFF and disconnect main circuit
breaker , or unplug cord at wall receptacle.
2. Remove the control panel.
3. Remove the two nuts securing the high limit bracket to the unit,
and pull the bracket from the unit.
4. Remove the two screws securing the high limit to the bracket,
and remove the high limit from the bracket.
5. Remove the two electrical wires from the high temperature
limit control.
6. Manually reset the control, then check for continuity
between the two terminals after resetting the control. If
the circuit is open, replace the control, then continue with
this procedure. (If the circuit is closed, the high limit is
not defective. Reconnect the two electrical wires.)

LIMIT CONTROL
(Continued)
Replacement T o avoid electrical shock or pr operty damage, move the
POWER switch to OFF and disconnect main circuit
breaker , or unplug cord at wall receptacle.
1. If the tube is broken or cracked, the control will open,
shutting off electrical power . The control cannot be reset.
2. Drain shortening from the frypot and discard. A substance
in the tube could contaminate the shortening.
3. Remove control panel.
4. Loosen small inside screw nut on capillary tube.
5. Remove capillary bulb from bulb holder inside the frypot.
6. Straighten the capillary tube.
7. Remove larger outside nut that threads into pot wall, and remove
defective control from control panel area.
8. Insert new control and replace screws.
9. Uncoil capillary line, starting at capillary tube, and insert
through frypot wall.
T o avoid electrical shock or other injury , run the capillary
line under and away from all electrical power wires and
terminals. The tube must never be in such a position where
it could accidentally touch the electrical power terminals.
10. Carefully bend the capillary tube as shown in photo and place
into bulb brackets.
2-3 1003

2-4. HIGH TEMPERATURE 11. Pull excess capillary line from pot and tighten nut into frypot wall.
LIMIT CONTROL
(Continued)
Be sure capillary bulb of high limit is positioned so it doesn’t
interfere with the carrier or get damaged when cleaning the
frypot.
12. With excess capillary line pulled out, tighten smaller nut.
13. Replace front panel.
14. Refill with shortening.
2-5. POWER SWITCH The POWER switch is a three way rocker switch with a center
OFF position. W ith the switch in the ON position the fryer
operates. W ith the switch in the PUMP position the filter pump
operates, but the unit will not heat.
Checkout
T o avoid electrical shock or pr operty damage, move the
POWER switch to OFF and disconnect main circuit
breaker , or unplug cord at wall receptacle.
1. Remove control panel.
2. Label and remove wires from the switch.
3. OFF position-should be open circuit anywhere on the switch.
4. ON position. Check from: #5 to #6 closed circuit
#l to #2 closed circuit
5. Pump position. Check from: #4 to #5 closed circuit
#3 to #2 closed circuit
Check across the jumpers on the wires of the POWER
switch. These jumpers have resistors and capacitors which may
be faulty .

Replacement
1. With control panel removed, and wires of f of the switch,
push in on tabs on the switch to remove from the panel.
2. Replace with new switch, and reconnect wires to switch
following the wiring diagram.
3. Replace the control panel.
2-6. TEMPERATURE PROBE The temperature probe relays the actual shortening temperature
REPLACEMENT to the control. If it becomes disabled, “E06” will show in the
display . Also, if the temperature is out of calibration more than
10°F , or 10°C, the temperature probe should be replaced. An Ohm
check can also be performed. See chart at end of this section.
1. Remove electrical power supplied to the fryer .
T o avoid electrical shock or pr operty damage, move the
POWER switch to OFF and disconnect main circuit
breaker , or unplug cord at wall receptacle.
2. Drain the shortening from the frypot.
3. Remove the control panel.
4. Using a 1/2" wrench, remove the nut on the compression fitting.
5. Remove the temperature probe from the frypot.
6. Place the nut and new ferrule on the new temperature probe and
insert the temperature probe into the compression fitting until it
extends one-half (1/2) inch (1.3 cm) into the frypot. Use the
temperature probe gauge provided in the temperature probe kit,
to ensure proper placement in frypot. See Figures 2-1 and 2-2.
