1.9 Built-in Filtration System Service Procedures
1.9.1 Filtration System Problem Resolution
One of the most common causes of filtration problems is placing the filter pad/paper on the bottom of
the filter pan rather than over the filter screen.
CAUTION
Ensure that filter screen is in place prior to filter pad/paper placement and filter pump
operation. Improper screen placement is the primary cause of filtration system
malfunction.
Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation of
the filter pad/paper, and ensure that the correct size is being used. While you are checking the filter
pad/paper, verify that the O-rings on the pick-up tube
of the filter pan are in good condition. A missing or
worn O-ring allows the pump to take in air and
decrease its efficiency.
If the pump motor overheats, the thermal overload
will trip and the motor will not start until it is reset. If
the pump motor does not start, press the red reset
switch (button) located on the rear of the motor.
If the pump starts after resetting the thermal overload
switch, then something is causing the motor to
overheat. A major cause of overheating is when
several frypots are filtered sequentially, overheating
the pump and motor. Allow the pump motor to cool
at least 30 minutes before resuming operation. Pump
overheating can be caused by:
Solidified shortening in the pan or filter lines,
or
Attempting to filter unheated oil or shortening
(cold oil is more viscous, overloading the
pump motor and causing it to overheat).
Sediment Particle
Oil Flow
Up for reverse
Down for forward
Sediment Particle
Gear Rotation

1-11
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.

9. Reconnect the unit to the electrical power supply, and verify that the pump is functioning correctly
using the MIB board in manual mode (i.e., using the fill function when engaged, the motor should
start and there should be strong suction at the intake fitting and outflow at the rear flush port.)
10. When proper operation has been verified, reinstall the back panels and the filter pan and lid.
11. Reconnect it to the electrical power supply and reposition the fryer under the exhaust hood to
return the fryer to service.
1.9.3 Replacing the Transformer or Filter Relay
Disconnect the fryer from the electrical power supply. Remove the left controller from the fryer to
expose the interior of the left component box. The transformer and relay on the left are located as
shown in the illustration below. NOTE: The right component box is identical to the left except that
the transformer and relay on the left side are not present. Once replaced, reconnect the power.
When replacing a filter relay in the left component box, ensure the 24VDC relay (8074482) is used.
Similar Frymaster fryers use a 24VAC relay, which can lead to confusion. The 24VDC is used in the
FilterQuick™ fryer.
1.10 Basket Lift Service Procedures
FQE30™ Series electric fryers may be equipped with automatic basket lifts. Basket lifts always come
in pairs, although each operates independently.
A modular basket lift (illustrated on the following page) is a self-contained sub-assembly consisting
of a pair of toothed rods, which support removable basket lift arms, a pair of reversible-drive gear
motors, and four microswitches. The gear motors engage the teeth of the rods, moving them up or
down depending upon the motors’ direction of rotation. The microswitches at the upper and lower
limits of movement stop the motors when the basket is in the full up or full down position.
Timing circuitry in the controller initiates and stops basket lift operation depending upon the variables
programmed by the operator. When the product button is pressed, the timing circuitry activates a coil
in the basket lift relay to supply power to the lower microswitch. The microswitches stop the motor at
the lift’s upper and lower travel limits and reverse the direction of current flow thus reversing the
motor direction.
When the product button is pushed on the controller, current flows through a coil in the basket lift
relay, causing the lower circuit to be activated. The basket lift lowers, closing the normally open
upper-micro-switch. When the downward-moving rod opens the lower normally closed microswitch,
the power to the motor ceases to flow. When the controller times out, the current to the relay coil is
cut, allowing the upper circuit to be activated. The basket lift rises and re-closes the lower
microswitch. When the basket lift rod clears the upper microswitch, the microswitch reopens, power
to the circuit is cut, and the motor stops. Pushing the product button restarts the cycle.

100-120V Configuration 208-250V Configuration
Problems with the basket lift can be grouped into three categories:
●Binding/jamming problems
●Motor and gear problems
●Electronic problems
Binding and Jamming Issues
Noisy, jerky or erratic movement of the lifts is usually due to lack of lubrication of the rods and their
bushings. Apply a light coat of Lubriplate®or similar lightweight white grease to the rod and
bushings to correct the problem.
With the modular basket lift, another possible cause of binding is improper positioning of the motor,
which prevents the gear from correctly engaging the teeth in the rod. To correct the problem, loosen
the screws that hold the motor in place and move it forward or backward until the rod has just enough
slack to be rotated slightly.
Motor and Gear Issues
With the modular basket lift, the most likely problem to be encountered in this category is erratic
motion of the lift due to a worn drive gear. Failure to keep the lift rod and bushings properly
lubricated will cause unnecessary wear of the gear. The problem is corrected by replacing the worn
gear.
If the lift cycles correctly but fails to remain in the up position (i.e., goes up, but then slowly settles
back down into the frypot), the problem is a failed motor brake. A failed motor brake cannot be
repaired and requires replacement of the motor itself.
If power is reaching the motor but the motor fails to run, the motor is burned out and must be replaced.

1-14
Electronic Issues
Within this category are problems associated with the relays, microswitches, capacitors, resistors,
interface board, wiring, and controls. The most common problem in this category is a lift that
continuously travels up and down. This is usually caused by a microswitch that is out of adjustment.
Troubleshooting the electronics of a modular basket lift is simply a process of verifying current flow
through the individual components up to and including the motor. Using a multimeter set to the 250
VAC range, check the connections on both sides of the component for the presence of the applied line
voltage. The schematic below and the wiring diagram on page 2-8 and 2-9 can identify the
components and wiring connection points.
1.11 ATO (Automatic Top-off) Service Procedures
The automatic top-off system is activated when the oil level falls below a sensor in the rear of the
frypot. The signal is sent to the ATO board to engage the return actuator to the frypot and turn on the
ATO pump. The pump draws oil from the JIB (Jug In Box) through the rear return manifold into the
rear of the frypot. Once the oil level has satisfied the sensor, the pump turns off and the actuator
closes.
The ATO board is located inside the box, behind the JIB (see Figure 1).
The power for the ATO board is supplied from the right hand
component box. The power passes through the transformer inside the
ATO box to the board.
