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/Cancel to
end bake mode.

Temperature Adjustment

1. Press Bake.

2. Set the temperature to 550°F (288°C) by pressing and holding the UP
arrow key.

3. Within 3 seconds, press and hold Bake until numeric digit(s) appear.
Release Bake key. The display now indicates the amount of degrees offset
between the original factory temperature setting and the current tempera­ture setting. If the oven control has the original factory calibration, the
display will read 00.

4. The temperature can now be adjusted up or down 35°F (19°C), in 5°F
increments. Press and hold the UP arrow key to adjust the temperature
higher until the desired amount of offset appears in the display. When
lowering the oven temperature using the DOWN arrow key, a minus sign
(-) will appear before the number to indicate that the oven will be cooler by
the displayed amount of degrees.

5. When you have made the desired adjustment, press OFF to go back to the
time of day display.

Note: Changing calibration affects normal Bake mode. The adjustments made
will not change the Self-Cleaning cycle temperature.

Electric Oven Control Fault Description

Fault
Code

F10 Runaway temperature

Likely Failure Condi­ton/Cause

Oven heats when no
cook cycle is pro­grammed.

Suggested Corrective Action

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 poor supply to range - Disconnect power, wait 30 seconds and reapply power.

2. Check/ reset ribbon harness connections between touch panel and EOC.

3. Test keyboard circuits. Replace touch panel if defective.

4. If keyboard circuits check good, replace the EOC.

F13 EOC internal software

error or failure

(some models).

1. Disconnect power, wait 30 seconds and reapply power. If fault returns upon power-up, replace EOC.

F14 Keyboard tail failure 1. Check for damage to the ribbon connection or that it is plugged in properly.

F30 Open oven sensor probe

circuit.

F31 Shorted oven sensor

probe circuit.

F90 Door lock motor or latch

circuit failure.

F91

1. (F30) 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. (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 assembly.

F92

3. If motor runs and switch contacts and wiring harness test good, replace the EOC.

If lock motor does not run:

F93

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.

F94

F95

3. If motor runs with test cord check continuity of wire harness to lock motor terminals. If harness is good, replace the
EOC.
