Safe Servicing Practices

To avoid the possibility of personal injury and/or property 

damage, it is important that safe servicing practices be 

observed. The following are some, but not all, examples 

of safe practices.

1. 

Do not attempt a product repair if you have any 

doubts as to your ability to complete it in a safe and 

satisfactory manner.

2. 

Before servicing or moving an appliance, remove 

power cord from electric outlet, trip circuit breaker 

to Off, or remove fuse.

3. 

Never interfere with the proper installation of any 

safety device.

4. 

Use only replacement parts specified for this 

appliance. Substitutions may not comply with safety 

standards set for home appliances.

5. 

Grounding: The standard color coding for safety 

ground wires is green or green with yellow stripes. 

Ground leads are not to be used as current carrying 

conductors. It is extremely important that the ser-

vice technician reestablish all safety grounds prior 

to completion of service. Failure to do so will create 

a potential hazard.

6. 

Prior to returning the product to service, ensure 

that:

• 

All electric connections are correct and 

secure.

• 

All electrical leads are properly dressed and 

secured away from sharp edges, high-tem-

perature components, and moving parts.

• 

All uninsulated electrical terminals, connec-

tors, heaters, etc. are adequately spaced 

away from all metal parts and panels.

• 

All safety grounds (both internal and external) 

are correctly and securely reassembled.

• 

All panels are properly and securely reassem-

bled.

Oven Calibration

Set the electronic oven control for normal baking at 

350°F. Allow oven to preheat to set temperature. Obtain 

an average oven temperature after a minimum of five 

cycles. Press the 

STOP key to end the Bake mode.

Temperature Adjustment

1. 

While in a non-cooking mode, press and hold the 

Bake key for 6 seconds. 

2. 

The current calibration offset (temperature adjust-

ment) should appear in the temperature display.

3. 

Use the number keys (0-9) to enter the desired 

amount of adjustments (up to 35°F).

4. 

Press the 

Self Clean key to change the sign of the 

adjustment to a (-), if necessary. A positive adjust-

ment will not display a sign.

5. 

Once the desired adjustment (-35° to 35° F) has 

been entered, press the 

Start key to accept the 

change or the 

Cancel key to reject the change.

Note: Changing calibration affects all baking modes. 

The adjustments made will not change the self-cleaning 

temperature.

ELECTRONIC OVEN CONTROL (EOC) FAULT CODE DESCRIPTIONS

Note: Generally speaking “F1X” implies a control failure, “F3X” an oven probe problem, and “F9X” a latch motor problem.

Failure Code/ Condition/Cause

Suggested Corrective Action

F10

Control has sensed a potential runaway oven 
condition. Control may have shorted relay, RTD 
sensor probe may have a gone bad.

Check RTD sensor probe and replace if necessary. If oven is overheating, disconnect power. If oven continues to overheat when 
power is reapplied, replace relay board and/or display board.

F11

Shorted Key: a key has been detected as 
pressed for a long period and will be considered 
a shorted key alarm and will terminate all 
oven activity.

Press any key to clear the error.

If fault returns, replace the keyboard (touch panel).

If the problem persists, replace the display board.

F13

Control's internal checksum may have 
become corrupted.

Press any key to clear the error.

Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace display board.

F14

Misconnected keyboard cable

Verify connection between display board and touch panel (2 ribbon cables). Make sure the cables are well connected at both ends.
If the cables are good, replace the touch panel.

If the problem persists, replace the display board.

F15

Controller self check failed.

Verify if relay board receives 120VAC between J4 pin 1 and 3. 

Verify the wiring between J2 on the relay board and P16 on the display board.

If wiring and 120VAC supply is good replace the display board.

If problem persists replace the relay board.

F23

The controller failed to communicate with the 
oven lights control board.

Verify wiring between P2 on the display board and P2 on the oven lights control board.

If wiring is good, replace oven lights board.

If the problem persists, replace the display board.

F30  Open RTD sensor probe/ wiring problem.
Note: EOC may initially display an "F10", thinking a 

runaway condition exists.

Check wiring in probe circuit for possible open condition.

Check RTD resistance at room temperature (compare to probe resistance chart). If resistance does not match the chart, replace the RTD sensor probe.

F31  Shorted RTD sensor probe / wiring problem.

Let the oven cool down and restart the function.

If the problem persists, replace the display board.

Note: F30 or F31 is displayed when oven is in active mode or an attempt to enter an active mode is made.

F43

The cooling fan speed, as read by the 
tachometer input of the EOC-display board, 
is abnormally too slow.

Determine first if the problem appears to be caused by a cooling fan not turning or turning slowly or by a problem with the sensing of 
the fan speed. Start a Bake and check during the first 15 seconds if the fan is turning (should feel air flowing through the vent above 
the upper oven door).
If the fan does not appear to be turning or turn slowly check the 120VAC at the fan. If 120VAC is present at the fan motor but the fan 
does not turn replace the fan motor. If 120VAC is not present at the fan motor when a Bake is started check the connection to the 
relay board (J3 pin 7) and Neutral: is there 120VAC on J3 pin 7? Does it reach the fan motor? Is the other terminal of the fan motor 
connected to Neutral? If the harness or relay board are faulty replace them.
If the fan appears to be normally turning but an F43 error code is generated, it means there is a problem with the reading of the fan 
speed sensor. Make sure the connection of the fan speed sensor is properly made (refer to wiring diagram), between the sensor on 
the fan and the EOC- display board.
For trouble-shooting purposes, it is possible to enter a test mode that will indicate on the display the reading of the fan speed in RPM: 
to enter the test mode, power-up the unit and within 30 seconds press and hold the upper oven Bake and Broil keys for 3 seconds 
(until you see all segments in the screen illuminated). Once in the test mode, pressing the upper oven Light key once will display the 
fan speed in RPM. In normal client mode the F43 error is generated for a fan speed below approximately 700 RPM.

F44

The cooling fan speed, as read by the 
tachometer input of the EOC- display board, 
is abnormally too fast.

Inspect the cooling fan. Does it appear to be turning normally (air flow, noise)? Verify the fan blade is well assembled.

Verify there is nothing blocking the air flow of the fan (that could make the fan turn faster).

Check the 120VAC voltage on the fan. A voltage higher than 120VAC + 10% could make it go too fast.
Make sure the connection of the fan speed sensor is properly made (refer to wiring diagram), between the sensor on the fan and the 
EOC- display board.

For trouble-shooting purposes, it is possible to enter a test mode that will indicate on the display the reading of the fan speed in RPM: to enter 
the test mode, power-up the unit and within 30 seconds press and hold the upper oven Bake and Broil keys for 3 seconds (until you see all 
segments in the screen illuminated). Once in the test mode, pressing the upper oven Light key once will display the fan speed in RPM. In normal 
client mode the F44 error is generated for a fan speed above approximately 2500 RPM.
If problem persists replace both the fan+sensor assembly and the EOC- display board.

F90

Door motor mechanism failure. 

Press any key to clear the error.
If it does not eliminate the problem, turn off power for 30 seconds, then turn on power.

Check wiring of Lock Motor, Lock Switch and Door Switch circuits.

Unplug the lock motor from the board and apply power (L1) directly to the Lock Motor. If the motor does not rotate, replace Lock Motor Assembly.
Check Lock Switch for proper operation (do they open and close, check with ohmmeter). The Lock Motor may be powered as in above 
step to open and close Lock Switch. If the Lock Switch is defective, replace Motor Lock Assembly.

If all above steps fail to correct situation, replace the display board and/or the relay board in the event of a motor that does not rotate.
If all the above steps fail to correct the situation, replace the display board in the event of a motor that rotates endlessly.

2-Speed Cooling Fan

The EOC controls the speed of the cooling fan. The cooling fan is activated at low speed during 

any cooking function and will remain on until the oven is cooled down. The high speed is activat-

ed during the broil (with open door) and during clean cycles only when the temperature is above 

apporximately 575°F/302°C.
