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.
F12 Bad Micro Identication. 1. Disconnect power, wait 30 seconds and reapply power.
2. If fault returne upon power-up, replace 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 at cables. No communication be-
tween 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.
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 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.

1. Check the wiring between EOC and Lock Motor Micro Switch
2. Replace the Motor Door Latch assembly if necessary.
3. Check for binding of the Latch Cam, Lock Motor Rod and Loc Motor Cam
4. Check to see if Lock Motor Coil is open. If open, replace Lock Motor Assembly.
5. Lock Motor continuously runs - if Micro Switch is open, replace Lock Motor Assembly.
6. (F92, 93, & 94) Check oven door Light Switch - if open, replace Switch.
7. If all situations above do not solve problem, replace EOC.
Note: Generally speaking, F1X implies a control failure, F3X an oven probe problem, and F9x a latch motor problem.
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
considered acceptable in the appliance repair trade. The manufacturer cannot

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 speci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 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 se-
curely reassembled.
All panels are properly and securely reassembled.

Appliance with Electronic Oven Control - 3XX
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. Press bake.
2. Set the temperature to 550°F (288°C) by pressing and holding the UP
arrow.
3. Within 3 seconds, press and hold bake until numeric digit(s) appear. Re-
lease bake key. The display now indicates the amount of degrees offset be-
tween the original factory temperature setting and the current temperature
setting. If the oven control has the original factory calibration, the display will
read 0.
4. The temperature can now be adjusted up or down 35°F (19°C), in 5°F incre-
ments. Press and hold the UP arrow to adjust the temperature higher until
the desired amount of offset appears in the display. When lowering the oven
temperature using the DOWN arrow, a minus sign (-) will appear before the
number to indicate that the oven will be cooler by the displayed amount of
degrees.
5. When you have made the desired adjustment, press clear off to go back to
the time of day display.
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.
