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:

Electonic Oven Control Fault Code Descriptions
Fault
Code
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.
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.
3. 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.

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.
F31

(EOC) over temperature.
Higher than normal
temperature detected on
the EOC circuit board.
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 lock motor does not operate replace lock motor
assembly.
3. If motor runs with test cord check continuity of wire harness to lock motor terminals. If harness is good replace
the EOC.

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