PROBLEM PROBABLE CAUSES CORRECTIVE ACTION
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
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
screws 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.
Pump won’t start.
OR
Pump stops during
filtering. (cont.)
C. Pump blockage.
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.
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.
Pump starts, but no
transfer takes place
or the transfer is
very slow.
A. Oil/shortening is too cold for
filtering.
A. To properly filter, the oil should
be at or near 350°F (177°C). At
temperatures lower than this, the
oil becomes too thick to pass
through the filter medium easily,
resulting in much slower oil
return and eventual overheating of
the filter pump motor. Ensure
that the oil is at or near frying
temperature before draining into
filter pan.
