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.

Fault
Code
F10
1. Check Oven Sensor Probe using the RTD scale found in the tech sheet. Replace if defective.
2. If oven is overheating disconnect power from the range and unplug connector P1 from power supply board 1.
Reapply power to the range. 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.
Runaway Temperature.
Oven heats when no cook
cycle is programmed.

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.
3. Replace the EOC.

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.

F60
1. Verify proper assembly of backguard panel. Check for damaged or loose panels, brackets, endcaps, etc.
2. Check for blocked ventilation slots in control panel rear cover.
3. Inspect oven vent for proper assembly and air flow.
4. Verify operation of cooling fan (if present)

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 assy.
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.

error or failure
• 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
keypad to end
Bake mode.
Temperature Adjustment
1.
While in a non-cooking mode, press and hold the
Bake
key pad for 6
seconds.
2.
The current calibration offset (temperature adjustment) should appear in
the temperature display.
3.
Use the number key pads (0-9) to enter the desired amount of adjustment
(up to 35°F).
4.
Press the
Self-clean
key pad 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 pad to accept the change or the
Cancel
key pad to reject the
change.
Note:
Changing calibration affects all Baking modes. The adjustments made
will not change the self-cleaning temperature.
