WARNING

Electric Shock Hazard

Disconnect power before servicing. Replace all parts and panels before operating. Failure to do so can result in death or

electrical shock.

Caution: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation.

Verify proper operation after servicing.

DIAGNOSTICS

Unplug range or disconnect power before performing the following checks:

The most common cause for control

■

failure is corrosion on connectors. Therefore, disconnecting and reconnecting wires will be necessary throughout test procedures.

Check all connections before replacing

■

components, looking for broken or loose wires, failed terminals, or wires not pressed into connectors far enough.

All tests/checks should be made with a

■

VOM or DVM having a sensitivity of 20,000 ohms per volt DC or greater.

Resistance checks must be made with

■

power cord unplugged from outlet, and with wiring harness or connectors disconnected.

Hidden EOC Functions

User activates all hidden EOC functions by pressing and holding the appropriate key for 5 seconds. Below is a list of hidden functions or features:

HIDDEN FUNCTIONS KEY

Stop Time

Temperature Adjustment

Press and hold BAKE pad for five (5)

■

seconds. Current offset, if any, is shown in 3-digit display. CAL is shown in 4-digit display (3 digits on right).

■

adjusts the temperature in 5.6°C (10°F) increments in the following sequence: Celsius: 0°, 5.6°, 11.1°, 16.7°, -16.7°,

-11.1°, -5.6°, 0°; (Fahrenheit: 0°, 10°, 20°, 30°, -30°, -20°, -10°, 0°) and so on.

Press START/ENTER pad to activate the

■

desired temperature adjustment. If the START/ENTER pad is not pressed within 5 minutes, adjustment is ignored.

BAKE temperature adjustment cannot

■

result in operating temperatures higher than 274°C (525°F) or lower than 77°C (170°F), as measured at oven cavity center.

Once the BAKE temperature has been

■

adjusted, BROIL temperatures are automatically offset to the same degree.

CLEAN temperature is also offset

■

automatically when BAKE temperature is adjusted. If BAKE temperature has been raised, CLEAN temperature is offset +3°C (+5°F). If BAKE temperature has been lowered, CLEAN temperature is offset -3°C (-5°F).

1. Verify failure if not displayed, using CANCEL/OFF key. Press key for 5 seconds until last error code is displayed.

2. Unplug range or disconnect power longer than 30 seconds.

3. Plug in range or reconnect power and observe for longer than 1 minute.

4. If failure remains, go to step 5.

5. Unplug range or disconnect power.

6. Replace control.

1. Verify failure if not displayed, using CANCEL/OFF key. Press for 5 seconds.

2. Unplug range or disconnect power.

3. If applicable, ensure membrane tail is seated in connector on back of control.

4. Plug in range or reconnect power and observe for longer than 1 minute.

5. If failure remains, go to step 6.

6. Unplug range or disconnect power.

7. Replace control.

1. Unplug range or disconnect power.

2. Disconnect sensor from harness.

3. Measure sensor value (between connector pins) between 1000 (900° F), (room temperature approx. = 1080 possible short. If measurements do not correlate to real temperature, or if short is found, replace sensor.

4. Trace the wires and connectors to the sensor from control, and back to control. If wire or connection is damaged, replace the harness.

5. Reconnect the sensor to the harness.

6. Plug in range or reconnect power.

7. Press BAKE and START/ENTER. Observe for longer than 1 minute. If failure remains, go to step 8.

8. Unplug range or disconnect power.

9. Replace control.

LIKELY FAILURE

CONDITION

Door and switches do not agree

Door latch not operating

Latch error during CLEAN

SUGGESTED CORRECTIVE ACTION PROCEDURE

1. Press CANCEL/OFF key. Program and start the CLEAN mode. Ensure door is closed and latched.

2. Unplug range or disconnect power.

3. Check integrity of wires and connectors from control to door switch, and control to door latch switch.

4. If no damage to wires or connectors:

-Check continuity of the door switch circuit from oven control. If continuity is not present, replace door switch

(If door switch is integral to the door latch motor assembly, replace entire door latch motor assembly).

-Check continuity of door latch switch circuit. If continuity is not present, replace door latch motor assembly.

5. Plug in range or reconnect power.

6. Press CANCEL/OFF key. Program and start the CLEAN mode, and observe for 1 minute to ensure that operation is normal.

1. Verify error code by pressing and holding CANCEL/OFF key for 5 seconds. Momentarily (less than 5 sec.) press CANCEL/OFF key again to remove error code display.

2. If the door is not latched (locked), ensure that it is completely closed. Press CLEAN then START/ENTER. Verify that the latch motor is operating.

3. Unplug range or disconnect power.

4. If motor did operate, check integrity of latch mechanism from cam/eccentric, through actuating rod, to latch pawl and door slot. Ensure that pawl aligns with the door slot. Correct any mechanical malfunction. Go to step 6.

5. If motor did not operate, check continuity of the latch motor and of electrical connections between oven control and door latch motor assembly.

-Ifcontinuity is not present, replace door latch motor assembly.

-Ifcontinuity is present, replace control.

6. Plug in range or reconnect power.

7. Put range into CLEAN mode to verify proper operation.

1. Unplug range or disconnect power.

2. Check wires and connectors from control to door switch, then from door switch to control.

3. If no damage to wires or connectors, replace door switch (If door switch is integral to the door latch motor assembly, replace entire door latch motor assembly).

4. Plug in range or reconnect power.

5. Press CANCEL/OFF key. Program and start the CLEAN mode, and observe for 1 minute to ensure that operation is normal.

STRIP CIRCUITS
