Electronic Oven Control (EOC) Fault Code Descriptions

Code

Condition / Cause

Suggested Corrective Action

F10

Control has sensed a potential run-
away oven condition, control may 
have shorted relay, and/or RTD 
sensor probe may have 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 the Electronic Oven Control (EOC).

F11

Shorted Key: A key has been 
detected as pressed (for a long 
period). Will be considered a short-
ed key alarm and will terminate all 
oven activity.

1. Press 

STOP key.

2. 

If the problem persists, replace the EOC.

F13

Control’s internal checksum may 
be corrupted.

• Press 

CLEAR key. - Disconnect power, wait 10 seconds, and reapply power. If fault returns upon power-up, 

replace EOC.

F14

Misconnected fl at cables. No 
communication between oven and 
controls.

1. 

Disconnect power. Verify the fl at cable connection between the touch panel or membrane and the EOC on P12 
and P13.

2. 

If the problem persist, replace the EOC.

F15

Control self-check failed

Replace the EOC display board

F30

Open RTD sensor probe/ wiring 
problem. Note: EOC may initially 
display an “F10,” thinking a run-
away condition exists.

1. 

Check wiring in probe circuit for possible open or short condition.

2. 

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

3. 

Let the oven cool down and restart the function.

4. 

If the problem persists, replace the EOC.

F31

Shorted RTD sensor probe /wiring 
problem.

F43

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

Determine fi rst 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 fi rst 15 seconds if the fan is turning (should feel air 
fl owing 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.

If the connection of the sensor is good but there is still an F43 error code generated the problem can be caused by 
the fan+sensor assembly or by the EOC- display board. Check the fan sensor (located near shaft of the fan, next to 
connector) for damage. If problem persists replace both the fan+sensor assembly and the EOC-display board.

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 fl ow, noise)? Verify the fan blade is well assembled.

Verify there is nothing blocking the air fl ow 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.

F62

Missing zero-cross signal.

The 60Hz synchronization signal (zero-cross) is sent by the EOC-Relay Board to the EOC-Display Board. Verify fi rst 
the connection between the EOC-Relay Board on connector J2 pin 5 and the EOC-Display Board on connector P2 pin 
5 (check for continuity).

If wiring is good, replace the EOC-Relay Board.

If problem persists, replace the EOC- Display Board.

F90

to

F94

Door motor mechanism failure.

1. 

Turn off power for 10 seconds, then turn on power. Test the door latch again (try to start a Clean cycle).

2. 

If it fails, check wiring of Lock Motor, Lock Switch and Door Switch circuits.

3. 

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.

4. 

Check Lock Switch for proper operation (do the contacts 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.

5. 

If all above steps fail to correct situation, replace the EOC.

Note: Generally speaking, F1X implies a control failure, F3X an oven probe problem, and F9x a latch motor problem.

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, exam-
ples 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 specifi ed 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 con-
ductors. It is extremely important that the service 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-temperature components, and moving parts.

• 

All uninsulated electrical terminals, connectors, 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 reassembled.

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 fi ve 
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 adjustment) 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 adjustment 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.

Cooling Fan and Fan Speed Sensor

This double wall oven is equipped with a cooling fan located on top of the upper cavity. The fan is controlled by the EOC. The cooling fan is activated anytime the oven 
is used for cooking or cleaning. It may also remain ON for some time after the oven has been used, until the oven cavity has cooled down enough. The fan motor is 
energized using relay K16 on the EOC-relay board.

The oven is equipped with a sensor that monitors the speed of the cooling fan. The sensor is connected to the EOC - display board, where the speed is read. Anytime 
the cooling fan is supposed to be active, the EOC checks the speed against a “speed too low” and a “speed too high” threshold. If the speed falls out of range, the 
EOC will generate an F43 error code (detecting fan is turning too slowly or not turning) or F44 error code (detecting fan is turning too fast).
