CHAPTER 6: OPERATOR TROUBLESHOOTING
6.3 Troubleshooting Fryers with Thermostat Controls
PROBLEM
Burner does not
light.
6.4 Troubleshooting the Built-In Filtration System
PROBLEM
Unit will not go into
melt cycle or stays in
melt cycle
continuously.
Fryer never reaches
frying temperature.
Pump won't start.
OR
Pump stops during
filtering.
CF SERIES GAS FRYERS
Probable Causes
A. Pilot is not lit.
B. Drain valve not fully closed.
C. No electrical power to unit.
D. No gas being supplied to unit.
PROBABLE CAUSES
Failed melt cycle switch.
Failed thermostat or thermostat out of
calibration.
A. Thermal overload switch has
tripped on an overheated motor.
Test: If the pump stopped
suddenly during the filtering
process, especially if after several
filtering cycles, the pump motor
has probably overheated. Place
the filter handle in the OFF
position, allow the pump to cool
for at least 45 minutes, and then
press the reset button on the pump
motor. Attempt to activate the
pump.
Corrective Action
A. Light pilot per instructions in
Chapter 3 of this manual.
B. Verify drain valve is fully closed.
C. Verify that unit is correctly
plugged in and that circuit breaker
is not tripped.
D. Verify that the gas line
connections are properly
connected, that any cutoff valves
between the fryer and the gas
main are open, and that the main
gas cutoff valve is open.
CORRECTIVE ACTION
Melt cycle switch must be replaced.
Call FASC.
Isolating the problem requires
additional troubleshooting beyond the
scope of operator troubleshooting.
Call FASC.
A. If the pump runs normally after
resetting the thermal overload
switch, the pump was overheated.
Always filter with the cooking
oil/shortening at or near frying
temperature.
Allow the pump motor to cool off
for about 10 minutes after
filtering two full frypots one after
the other.
Check the filter paper after each
frypot is filtered. Replace the
paper if there is a large
accumulation of sediment.
