PROBLEM
A. Thermal overload switch has tripped
B. Failed filter-handle microswitch.
Pump won't start.
OR
Pump stops during
filtering.
C. Pump blockage.
PROBABLE CAUSES
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.
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.
Test: Close the drain valve. 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. Pull the
filter pan from the unit and then
activate the pump. If the pump motor
hums and then stops, the pump is
blocked.

CORRECTIVE ACTION
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 paper between
filterings. Replace the paper if there
is a large accumulation of sediment.
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.
C. Pump blockages are usually caused
by sediment build-up in the pump
due to improperly sized or installed
filter paper and failure to use the
crumb screen. Call FASC to have
blockage cleared.
Ensure that filter paper is of the
proper size and is installed properly,
and that the crumb screen is used.
