prevent igniter module lockout. The igniter location is factory set and should not require adjustment unless the
igniter has been replaced or has been knocked out of
adjustment.
Should adjustment become necessary, contact local service agency.
HIGH LIMIT CONTROL
The function of high limit control is to shut the unit down
in the event of a thermostat failure which would allow the
cooking oil to be overheated. The operating temperature
of the high limit control is 435°F or 60°F (223.8°C or
15.5°C) higher than the highest temperature allowed by
the thermostat.
In the event of a high limit "shutdown", the entire control
system will be put out of operation.
DO NOT attempt to restart the fryer until the temperature
of the cooking oil has lowered to approximately 350°F

within 3 seconds.
Defective high voltage ignitor wire Replace high voltage lead.
Defective ignitor Allowing spark leakage or intermittent
spark. Replace ignitor. (Sparking can be
clearly heard when listening at front of unit
with door open.)
Improper spark gap Check and set gap to. 160".
Obstructed ignitor Remove ignitor, check ignitor gap for
burner particles or carbon, clean off
particles and reinstall ignition.
Door switch malfunction Be sure door switches are activating when
doors are closed. (When doors are open,
pull out door switch posts to activate and
observe operation.)
No electrical power
Check for 110V supply to fryer.
Check for 24V grounded ignition system
power. Check for 24V AC to ground at
wire #1 of both power switches. If no
voltage, then check for AC voltage
input/output at rear most transformer.
Check for 24 VAC isolated "computer"
power between wires # 16 & # 17 on both
interface boards. If no voltage, check for
AC voltage input/output of forward most
transformer.
Make sure all wiring harness connectors
are engaged and locked in place.

TROUBLESHOOTING GUIDE (Cont.)
PROBLEM CAUSE REMEDY
NO HEAT (Cont.) Malfunctioning sensors Check thermistor probe terminations
on "back-up" interface P.C. boards. Be
sure terminations are not touching or
shorted. Probe terminations are
labeled on P.C. boards as "PRB-1" and
"PRB-2" (two terminals each) remove
one or both PRB-1 wires. Measure
OHMS resistance through the wires. If
fryer is cold, resistance is about 100-K
OHMS. If reading is infinity-probe is
defective-replace probe. If reading is
zero-check wires for a direct short,
replace probe if necessary. Repeat
this procedure and check PRB-2 wires.
NOTE: PRB-2 is probe connection
for computer.
PRB-1 is probe connection
for back-up interface control.
Computer & back-up interface If computer is displaying "PROB" or
system has no display, check interface
harness (from computer to interface
P.C. boards) to be sure all connectors
are properly engaged and check
connectors to be sure all pins are
securely in place. If harness seems
to be in proper condition, but computer
still displays "PROB", refer to
"Malfunctioning sensors". Disconnect
computer wiring harness from P.C.
boards. Fryer should operate on
back-up temperature control. This
would indicate a defective computer or
computer interface. Replace as
required. If unit still fails to operatecheck for 24V supply across terminal
#5 and #6 of back-up interface
board. If power supply is confirmedreplace P.C. board.
TROUBLE LIGHT "FLASHES" Normal operation
THEN "HEATING" LIGHT COMES ON
TROUBLE LIGHT COMES ON Indicates power to ignitor module Check 3A fuse on ignitor module. If
AND STAYS ON input, but no power out. bad, look for short circuit or ground
on ignitor board output (overload)
before replacing fuse.
Defective ignitor module. Replace.
UNIT HAS NO FAT MELT CYCLE Computer is inoperative and unit is
operating on "back-up" interface board
Make sure computer harnesses are
attached.
Refer to "Malfunctioning Sensor" section.
NOTE: If above checks OK, then replace
computer.
COMPUTER (INTERMITTENT)
Bad computer connections Faulty
harness.
General wiring problems related to
interface wire harness.
Check for pins not seated in connections. FRYER OPERATING WITHOUT
Check for connectors to be mated and
locked in position.
