If the motor runs but the pump does not return oil, there is a blockage in the pump. Incorrectly sized
or installed paper/pads 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
NEVER
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.
DANGER
DO NOT drain more than one full frypot or two split frypots 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.
3. Disconnect the flexline running to the oil-return manifold at
the rear of the fryer as well as the pump suction flexline at
the end of the filter pan connection (see photo to the right).
4. Loosen the nut and bolt which secure the bridge to the oil-
return manifold.
5. Remove the cover plate from the front of the motor and
disconnect the motor wires.
6. Remove the two nuts and bolts which secure the front of the
bridge to the cross brace and carefully slide the bridge
rearward off the cross brace until its front end can be
lowered to the floor. Undo the single nut holding it in place
in back. Be careful not to let the rear of the bridge slip off
the manifold at this point.
7. Get a good grip on the bridge, carefully pull it forward off
the oil-return manifold, and lower the entire assembly to the
floor. Once on the floor, pull the assembly out the front of the fryer.
8. When required service has been completed, reverse steps 4-7 to reinstall the bridge.
Disconnect flexlines indicated by
the arrows.
