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 examples, but without
limitation, of such practices.
1. Before servicing or moving an appliance remove power cord from electrical
outlet, trip circuit breaker to OFF, or remove fuse.
2. Never interfere with the proper installation of any safety device.
3. 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 safety hazard.
4. 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.
E.O.C. ELECTRICAL CONNECTIONS
• 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.
Oven Calibration
Set the electronic oven control for normal baking at 350°F. Obtain an
average oven temperature after a minimum of 5 cycles. Press Cancel to
end bake mode.
Temperature Adjustment
1. Set EOC to bake at 550°F.
2. Within 5 seconds of setting 550°F, press and hold the bake pad for
approximately 15 seconds until a single beep is heard (longer may
cause F11 shorted keypad alarm).
3. Calibration offset should appear in the display.
4. Use the slew keys to adjust the oven temperature up or down 35°F in
5°F increments.
5. Once the desired (-35° to 35°) offset has been applied, press Cancel.
Note: Changing calibration affects normal Bake mode. The adjustments
made will not change the Self-Cleaning cycle temperature.

1. (F10 only) Check RTD Sensor Probe & replace if necessary. If oven is overheating,
disconnect power. If oven continues to overheat when the power is reapplied, replace EOC.
Severe overheating may require the entire oven to be replaced should damage be extensive.
2. (F11, 12 & 13) Disconnect power, wait 30 seconds and reapply power.
3. (F11, 12 & 13) If fault returns upon power-up, replace EOC.
F30
F31
Open probe connection.
Shorted Probe connection.
1. (F30 or F31) Check resistance at room temperature & compare to RTD Sensor resistance
chart. If resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor
wiring harness between EOC & Sensor Probe connector.
2. (F30 or F31) Check resistance at room temperature, if less than 500 ohms, replace RTD
Sensor Probe. Check for shorted Sensor Probe harness between EOC & Probe connector.
F40 Cooktop Lockout error (some models). 1. (F40) Check the wiring.
2. (F40) Replace the Cooktop Lockout Control Board.
3. (F40) Replace EOC.

1. (F90, 91, 92, 93 & 94) Check the wiring between EOC & Lock Motor Micro Switch.
2. (F90, 91, 92, 93 & 94) Replace the Motor Door Latch assembly if necessary.
3. (F90, 91, 92, 93 & 94) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor
Cam.
4. (F90, 91, 92, 93 & 94) Check to see if Lock Motor Coil is open. If open, replace Lock Motor
Assembly.
5. (F90, 91, 92, 93 & 94) Lock Motor continuosly 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.
