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.

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

2. The current calibration offset (temperature adjustment) should appear in

3. Use the number key pads (0-9) to enter the desired amount of adjustment

4. Press the Self-clean key pad to change the sign of the adjustment to a (-)

5. Once the desired adjustment (-35° to 35° F) has been entered, press the

Note: Changing calibration affects all Baking modes. The adjustments made will not change the self-cleaning temperature.

• 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.

Electronic Oven Control (EOC) over temperature.

Higher than normal temperature detected on the EOC circuit board

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.

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

2. Check/reseat ribbon harness connections.

3. Replace the EOC.

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

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.

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)

Door lock motor or latch circuit failure

EOC Internal voltage test error or 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 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.

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