SERVICE DATA SHEET
Appliance with 5xx 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
considered 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.
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 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 se-
curely 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
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.

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

returns upon power-up, replace EOC.
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.
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.
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.
