Code
Description of Error Code Suggested Corrective Action
F10 Runaway temperature.
Oven heats when no cook cycle
is programmed.
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 RTD 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.
F11 Shorted keypad or selector
switch.
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.
F12 EOC Internal software error or
failure.
Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.
F13
F20 Communication failure between
oven and cooktop control boards
1. Reset power supply to range – Disconnect power, wait 30 seconds and reapply power.
2. Check/reseat communication between oven (MACS BUS) and cooktop controller (MACS2)
3. If problem persists, replace each board individually then retest until problem clears
F30 Open oven sensor probe circuit. 1. Check resistance at room temperature & compare to RTD Sensor resistance chart.
2. If resistance is correct replace the EOC.
3. If resistance does not match the RTD chart replace RTD Sensor Probe.
4. Check Sensor wiring harness between EOC & Sensor Probe connector.
F31 Shorted oven sensor probe
circuit.
1. Check resistance at room temperature, if less than 500 ohms, replace RTD Sensor Probe.
2. Check for shorted Sensor Probe harness between EOC & Probe connector. If resistance is correct replace the
EOC.
F40 Communication failure between
oven and cooktop control boards
1. Reset power supply to range – Disconnect power, wait 30 seconds and reapply power.
2. Check/reseat communication between oven (MACS BUS) and cooktop controller (MACS2)
3. If problem persists, replace each board individually then retest until problem clears
F90 Door lock motor or latch circuit
failure.
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

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, Clear, Off or 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 sounds (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, Clear,
Off or Cancel.
Note: Changing calibration affects normal Bake mode. The adjustments made
will not change the Self-Cleaning cycle temperature.
Modular Control Systems
This appliance is equipped with a modular system of controls. The modular
system consists of various boards which communicate with one another to drive
cooking functions. Oven functions, if available, operate through an oven user
interface (UI or UIB) and an oven relay board. Cooktop functions, if available,
operate through a cooktop UI/UIB and a cooktop relay board. There may be
additional boards which work within the system to drive specic functions (refer
to the schematics and diagrams and this sheet). Low voltage operating and
communications power for the modular boards is provided through the wiring
schemes. The boards that generate low voltage operating and communications
power depend upon the individual control system (refer to the schematics and
diagrams on this sheet). These voltages are only the operational voltages. Do
not use these voltages as conrmation of communication between the boards.
Communication occurs through software programming on each board. This
communication is not detectable by volt ohmmeters. The programming is self-
monitored and the UI displays will show error codes based on detected failures.
The individual boards are not eld repairable. See the schematics and diagrams
included on this sheet for more unit-specic details.
