Electronic Oven Control (EOC) Fault Code Descriptions
Code Condition / Cause Suggested Corrective Action
F10 Control has sensed a potential runaway oven condition,
control may have shorted relay, and/or RTD sensor
probe may have gone bad.
1. 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 shorted 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. 1. Press CLEAR key. - Disconnect power, wait 10 seconds, and reapply power. If fault returns
upon power-up, replace EOC.
F14 Misconnected at cables. No communication between
oven and controls.
1. Disconnect power. Verify the 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 1. Replace the EOC display board
F30

F31
Open RTD sensor probe/ wiring problem. Note: EOC
may initially display an “F10,” thinking a runaway condi-
tion exists.
Shorted RTD sensor probe /wiring problem.
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 resis-
tance 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.
F43 The cooling fan speed, as read by the tachometer input
of the EOC-display board is abnormally too slow.
1. Determine rst if cooling fan is not turning or turning slowly or if a problem exists with the
sensing of the fan speed. Start a Bake and check during the rst 15 seconds if the fan is
turning (should feel air owing through the vent above the upper oven door).
2. If the fan is not turning or turns 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.
3. If the fan appears to turn normally 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.
4. 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.
5. 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 techometer input
of the EOC-display board, is abnormally too fast.
1. Inspect the cooling fan. Does it appear to be turning normally (air ow, noise)? Verify the
fan blade is well assembled.
2. Verify there is nothing blocking the air ow of the fan (that could make the fan turn faster).
3. Check the 120VAC voltage on the fan. A voltage higher than 120VAC + 10% could make it
go too fast.
4. Make sure the connection of the fan speed sensor is properly made (refer to wiring dia-
gram), between the sensor on the fan and the EOC-display board.
5. 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.
6. If problem persists replace both the fan+sensor assembly and the EOC-display board.
F62 Missing zero-cross signal. 1. The 60Hz synchronization signal (zero-cross) is sent by the EOC-Relay Board to the
EOC-Display Board.
2. Verify 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).
3. If wiring is good, replace the EOC-Relay Board. If problem persists, replace the EOC- Dis-
play 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 ohm-
meter). 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 im-
portant 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 specied 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 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 ade-
quately 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 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 nec-
essary. 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.
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 activated during the broil (with open door) and during clean
cycles only when the temperature is above apporximately 575°F/302°C.
