6.4 Troubleshooting the Built-in Filtration System
PROBLEM PROBABLE CAUSES CORRECTIVE ACTION
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.
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 ten minutes after
filtering two full frypots one after
the other.
Check the filter pad between
filtering. Replace the pad if there
is a large accumulation of
sediment.
B. Failed filter handle microswitch.
Test: If this is a multi-pot fryer,
attempt to operate the pump using
a different handle. If the pump
starts, the handle microswitch is
either out of alignment or has
failed.
When the handle is placed in the
ON position, the lever on the
microswitch should be firmly
pressed against the switch. If so,
the switch has failed. If not, the
switch is loose and/or misaligned.
B. If the switch is loose, tighten the
nuts and bolts holding it in place,
ensuring that when the handle is
placed in the ON position, the
lever on the microswitch is
pressed firmly against the switch.
If the switch has failed, call
FASC.
