Electronic Oven Control (EOC) Fault Code Descriptions
Code Condition / Cause Suggested Corrective Action
F10 Control has sensed a potential runaway oven con-
dition, 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 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. • 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 be-
tween oven and controls.
1. Disconnect power. Verify the fl at cable connection between the touch panel or mem-
brane and the EOC on P12 and P13.
2. If the problem persist, replace the EOC.
F30
or
F31
Open RTD sensor probe/ wiring problem. Note: EOC may initially display an “F10,” thinking a runaway condition 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
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.
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 Mo-
tor. 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.
Service Data Sheet
Appliance with Electronic Oven Control
NOTICE: This service data sheet is intended for use by persons having electrical and mechanical training and a level of knowledge of these subjects generally consid- ered acceptable in the appliance repair trade. The manufacturer cannot be responsible, nor assume any liability, for injury or damage of any kind arising from the use of this data sheet. IMPORTANT NOTE: This unit includes an EOC (electronic oven control). This board is not fi eld-repairable.
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. 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.
