Replacing The Filter Motor, Filter Pump And Related Components - Frymaster OCF30E Service & Parts Manual

 Solidified shortening in the pan or filter
lines, or
 Attempting to filter unheated oil or
shortening (cold oil and shortening are
more viscous, overloading the pump
motor and causing it to overheat).
If the motor runs but the pump does not return
oil, there is a blockage in the pump. Incorrectly
sized or installed paper will allow food particles
and sediment to pass through the filter pan and
into the pump. When sediment enters the pump,
the gears bind, causing the motor to overload,
again tripping the thermal overload. Shortening
that has solidified in the pump will also cause it
to seize, with the same result.
A pump seized by debris or hard shortening can
usually be freed by manually moving the gears
with a screwdriver or other instrument.
Disconnect power to the filter system, remove the input plumbing from the pump, and use a
screwdriver to manually turn the gears.
● Turning the pump gears in reverse will release a hard particle.
● Turning the pump gears forward will push softer objects and solid shortening through the pump
and allow free movement of the gears.
Incorrectly sized or installed paper/pads will also allow food particles and sediment to pass through
and clog the suction tube on the bottom of the filter pan. Particles large enough to block the suction
tube may indicate that the crumb tray is not being used. Pan blockage can also occur if shortening is
left in the pan and allowed to solidify. Blockage removal can be accomplished by forcing the item out
with an auger or drain snake. Compressed air or other pressurized gases should not be used to force
out the blockage.
1.9.2 Replacing the Filter Motor, Filter Pump, and Related Components
1. Remove the filter pan and lid from the unit. Drain the frypots into a Shortening Disposal Unit
(SDU) or other appropriate metal container.
DO NOT drain more than one full frypot into the SDU at one time.
2. Disconnect the fryer from the electrical power supply and reposition it to gain access to both the
front and rear.
