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:

INFORMATION ENCLOSED
REPLACE CONTENTS IN BAG
• 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.
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 clear/off 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 clear/off.
Note: Changing calibration affects normal Bake mode. The adjustments made will not
change the Self-Cleaning cycle temperature.

Likely Failure Condition/Cause
Fault Code
1. (F10 only) Check RTD Sensor Probe & harness. 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.
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 open or shorted Sensor Probe harness between EOC & Probe connector.
IF LATCH MOTOR RUNS:
1. (F90, 91, 92, 93 & 94) Check the wiring between EOC & Lock Motor Micro Switch.
2. (F90, 91, 92, 93 & 94) Check the contacts of Micro-Switch on latch motor assembly.
If contacts are open when motor cam depresses switch, replace Lock Motor Assembly.
3. (F90, 91, 92, 93 & 94) Check for binding of the Latch Cam, Lock Motor Rod & Lock Motor Cam.
4. If all situations above do not solve probem, replace EOC.
IF LATCH MOTOR DOES NOT RUN
1. (F90, 91, 92, 93 & 94) Check to see if Lock Motor Coil is open. If open, replace Lock Motor Assembly.
2. (F92, 93 & 94) Check oven door Light Switch - if open, replace Switch.
3. If all situations above do not solve probem, replace EOC.
