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.
• 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
STOP
or
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 keypad 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
STOP
or
CLEAR OFF
.
Note:
Changing calibration affects normal Bake mode. The adjustments made will not
change the self-cleaning cycle temperature.

Likely failure
condition/cause
Suggested Corrective Action
Shorted keypad or selector
switch.
F11
1. Reset power supply to range - Disconnect power, wait 30 seconds and reapply power.
2. Check/reseat ribbon harness connections between touch panel and EOC.
3. Test keyboard circuits. Replace touch panel if defective.
4. If keyboard ciruits check good replace the EOC.
EOC Internal software error
or failure.
F12
F13
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
Open oven sensor probe
circuit.
Shorted oven sensor probe
circuit.
F30
1. (F30) Check resistance at room temperature & compare to RTD Sensor resistance chart. If resistance is correct replace the EOC. If
resistance does not match the RTD chart replace RTD Sensor Probe. Check Sensor wiring harness between EOC & Sensor Probe
connector.
2. (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. If resistance is correct replace the EOC.

If lock motor runs:
1. Test continuity of wiring between EOC and lock switch on lock motor assy. Repair if needed.
2. Advance motor until cam depresses the plunger on lock motor switch. Test continuity of switch contacts. If switch is open replace
lock motor assemblyy.
3. If motor runs and switch contacts and wiring harness test good, replace the EOC.
If lock motor does not run:
1. Test continuity of lock motor windings. Replace lock motor assembly if windings are open.
2. Test lock motor operation by using a test cord to apply voltage. If motor does not operate replace lock motor assy.
3. If motor runs with test cord check continuity of wire harness to lock motor terminals. If harness is good replace the EOC.
Door lock motor or latch
circuit failure.
If Oven is cold:
1. If fault code is present with cold oven test oven temperature sensor probe circuit resistance. Use RTD scale found in the tech sheet.
2. Replace probe or repair wiring connections if defective.
3. If temperature sensor probe circuit is good but fault code remains when oven is cold replace the EOC.
If Oven is overheating:
1. If oven is severely overheating/heating when no cook cycle is programmed test oven temperature sensor probe circuit resistance using
the RED scale found in the service tech sheet. Also verify that the temperature sensor probe in properly installed in the oven cavity.
2. Disconnect power from the range, wait 30 seconds and reapply power. If oven continues to heat when the power is reapplied, replace
the EOC.
NOTE:
Severe overheating may require the entire oven to be replaced should damage be extensive.
