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

Gear Rotation

Sediment Particle

worn O-ring allows the pump to take in air and decrease its efficiency.

If the pump motor overheats, the thermal overload

Oil Flow

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

Sediment Particle

Up for reverse

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,

Down for forward

 Attempting to filter unheated oil or shortening

(cold oil is more viscous, overloading the pump motor and causing it to overheat).

1-10

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

Disconnect flexlines indicated by the arrows.

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.

1-11

8. When required service has been completed, reverse steps 4-7 to reinstall the bridge.

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

1-12

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.

Problems with the basket lift can be grouped into three categories:

● Binding/jamming problems

● Motor and gear problems

● Electronic problems

100-120V Configuration

208-250V Configuration

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.

1-13

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.

1.12 MIB (Manual Interface Board) Service Procedures

The MIB (Manual Interface Board) oversees and controls filtration. It receives and sends data over the CAN (Controller Area Network) to and from various sensors and controllers. It activates the filtration cycle, controlling when actuators should open and close.

The MIB controller is located inside the left cabinet (see Figure 6). In normal operation a cover hides the MIB controls and only the LED display is visible. The cover is held in place with three torx screws. In normal operation, an “A” is displayed for automatic mode. The MIB control board is useful for diagnostic purposes. It

allows manual operation of both the actuators and filter pump without using the controller.

1.12.5 Replacing the MIB Board

Disconnect the fryer from the electrical power supply. Remove the torx screws from the MIB cover, exposing the MIB board (see Figure 11). Removing the screw at top center lets the MIB board hinge down. Carefully remove the plugs on the rear of the board (see Figure 12). Replace with a new MIB board and reverse steps to

reassemble. Once replaced, CYCLE POWER TO ENTIRE FRYER SYSTEM. See next section to reset

control power. Check software version # and if necessary update the software. If a software update was necessary, follow the instructions to update the software on in section 1.16 ensuring the MIB reset button is pressed and held for five seconds at the end of the update to update the MIB.

Figure 11

1.12.6 Control Power Reset Switch

The control power reset switch is a momentary rocker switch located behind the control box (see Figures 13 and 14) above the JIB that resets all power to all the controllers and boards in the fryer. It is necessary to reset all power after replacing any controller or board. Press and hold the switch for at least ten seconds when resetting the control power to ensure power has sufficiently drained from boards.

1.13 Bulk Service Issues

1.13.1 Bulk MIB Tests The FilterQuick™™ fryer will ONLY operate with bulk systems that have the three-pole

float switch. If the float switch is the older two-pole switch, call the bulk oil provider. These float switches are polarity specific which may short to ground and damage an MIB board.

Normal measurements (MIB J6 8-pin connector with everything connected)

AC voltage measurements:

Pin 1 to Pin 2 - 24 VAC. Pin 2 to Pin 8 - 24 VAC when waste tank is full, 0 VAC when it is not full. Pin 2 to Pin 3 - 24 VAC when RTI fill pump is on, 0 VAC when it is off.

Using the bulk test box, PN# 108-0716 allows a quick and easy way to check the 24VAC, the waste full switch and when the bulk fresh oil pump is operating.

Troubleshooting

All return and drain valves should be closed and pump should be off while the MIB is resetting. If any of the valves or the pump is on during reset, the MIB board is bad or wires are shorted.

Bulk fresh oil pump is not operating or JIB is not filling:

See page 1-25 to ensure that no other function is taking priority over adding oil to jug.

1. Reset the power; wait 60 seconds and see if the valve opens.

With the JIB button pressed:

2. Voltage at MIB board from Pin 1 to Pin 2 should be 24 VAC; if not, check connections from bulk fresh oil pump 24VAC transformer and check transformer.

3. Voltage at MIB board from Pin 1 to Pin 3 should be 24 VAC when filling JIB or vat; if not, the MIB board is bad or wires to pump relay are shorted or both.

4. Voltage at Add pump relay should be 24 VAC; if not, check wiring from MIB board. The relay is located at the fresh oil tank pump system.

5. Check voltage at ATO board on J8. Pin 9 to Pin 1 should be 24 VAC with the orange button pressed.

Waste full signal:

Pin 2 to Pin 8 should be 24 VAC when full, 0 VAC when not full; if no voltage level change, the connection from bulk oil waste switch or MIB board is bad.

2. To refill jug press and hold the orange reset button above the jug until the jug is full.

3. Release the button to stop filling.

*NOTE: The jug may not fill if any of the following are in progress:

If FILTER NOW? YES/NO, CONFIRM YES/NO, or SKIM VAT is displayed, the fill jug button is disabled until either a filter is complete or until no is chosen.

The system also checks these conditions. The following must be met before jug fill is allowed.

 Solenoid closed  Orange fill button pressed longer than 3 sec.  Waste valve closed  Filter Now? Yes/No, Confirm Yes/No, or Skim Vat cannot be displayed  System power cycle (all boards – controllers, MIB, AIF and ATO) after changing setup from

JIB to Bulk (use momentary reset). Ensure reset is pressed and held for at least ten seconds.

 No filtration or other filter menu selection can be in process.

Other factors that may not allow fill jug from bulk –

 Defective solenoid  Defective switch  Bulk fresh oil pump issue  Bulk fresh oil relay issue

If using multiple fryer systems that are both attached to the bulk fresh oil system, they may not be able to fill both units at the same time if they have a bulk fresh oil unit with a single head. Some bulk fresh oil units have dual heads which can fill more than one fryer simultaneously.

1.14 AIF (Automatic Intermittent) Filtration Service Procedures

The AIF (Automatic Intermittent Filtration) board controls the actuators that open and close the drain and return valve. The AIF boards are located inside a protective housing under each frypot (see Figure 13).

Figure 13

1.14.1 AIF Troubleshooting

Problem Probable Causes Corrective Action

A. Check pins 5 and 6 of J2 at the MIB

board. Should read 24VDC. Check voltage on pins 5 and 6 at the other end of harness and ensure 24VDC is present. Continue to check pins 5 and 6 for 24VDC on plugs J4 and J5 on the AIF boards.

B. Ensure the actuator is plugged into the

proper connection (J1 for FV return, J3 for DV return and J6 for FV drain and J7 for DV drain).

C. Check power on the connector of the

problem actuator while trying to manually open or close an actuator. Pins 1 (Black) and 4 (White) should read +24VDC when the actuator is opening. Pins 2 (Red) and 4 (White) should measure -24VDC when the actuator is closing). If either voltage is missing, the AIF board is likely bad. Test the actuator by plugging into another connector. If the actuator operates, replace the board.

D. Check resistance of the potentiometer

between pin 3 (blue wire) and pin 4 (gray/white wire). Closed should read 0-560Ω. Open should read 3.8K Ω –

6.6K Ω.

E. If proper voltages are present at the

connector and actuator doesn’t operate, reset power to the fryer. If it still doesn’t operate replace the actuator.

A. Ensure the actuator is plugged into

correct connection (J1 for FV return, J3 for DV return and J6 for FV drain and J7 for DV drain).

B. Ensure the locator pin is in proper

position in plug J2. See table B on page 2-6.

1.14.3 Replacing an AIF (Automatic Intermittent Filtration) board

Disconnect the fryer from the electrical power supply. Locate the AIF board to be replaced under a frypot. Mark and unplug the harnesses. The AIF board assembly is held in place with one screw in the front of the assembly (see Figure 14). Remove the screw and the front of the assembly drops down (see Figure 15) and the back tab slides out of the bracket attached to the frypot (see Figure 16). Reverse steps to reassemble,

ensuring that the new AIF assembly slides into the slot in the rear of the bracket. Once complete, CYCLE POWER TO ENTIRE FRYER SYSTEM. See section 1.12.6 on page 1-23 to reset control power. Check

software version # and if necessary update the software. If a software update was necessary, follow the instructions to update the software in section 1.16.

Figure 14 Figure 15 Figure 16

1.14.4 Replacing a Rotary Actuator

Disconnect the fryer from the electrical power supply. Locate the actuator to be replaced and mark and

unplug the actuator. The actuators are held in place by two hex key screws. Loosen the 3/32” hex key screws. It may be necessary to remove a gas line to the burner when removing a drain actuator. Remove the actuator from the valve stem. Align the actuator with the valve stem and attach the new actuator. Tighten the two hex key screws. Reconnect power and test the actuator.

NOTE: Rotary actuators have two different part numbers, which are mirror images of each other that

correspond to their mounting position.
