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.

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

2. Check/reseat ribbon harness connections.

3. Replace the EOC.

F18

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

(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.

(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

Electronic Oven Control

(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 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.

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

EOC Internal voltage test

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

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

(up 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-cleaning temperature.

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.
