DIAGNOSTICS

CAL is shown in 4-digit display (3 digits on right).

Disconnect power and perform the following checks:

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. Voltage checks must be made with all connectors attached to the boards. Resistance checks must be made with power cord unplugged from outlet, and with wiring harness or connectors disconnected.

Temperature Adjustment

temperature in 10°F increments in the following sequence: 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 525°F or lower than 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 +5°F. If BAKE temperature has been lowered, CLEAN temperature is offset -5°F.

n Press and hold BAKE pad for five (5) seconds. Current

offset, if any, is shown in 3-digit display.

SUGGESTED CORRECTIVE ACTION PROCEDURE No action required. 1. Verify failure if not displayed, using CANCEL/OFF key. Press key for 5 seconds until last error code is displayed. 2. Disconnect power longer than 30 seconds. 3. Re-apply power and observe for longer than 1 minute. 4. If failure remains, disconnect power, replace control. 1. 2. 3. 4. 5.

Verify failure if not displayed, using CANCEL/OFF key. Press for 5 seconds. Disconnect power. If applicable, ensure membrane tail is seated in connector on back of control. Re-apply power and observe for longer than 1 minute. If failure remains, disconnect power, replace control.

1. Measure sensor value (between connector pins) between 1000 Ω @ 32° F and 2697 Ω @ 900° F (room temperature approx. = 1080 Ω). If measurement does not correlate to real temperature, disconnect power, replace sensor and refer to steps 3-5. Also measure from sensor connector to sensor casing for possible short. 2. Trace wires and connectors to sensor from control, then from sensor back to control. If all connections are made and no wire damage, refer to step 3. 3. Disconnect power longer than 30 seconds. 4. Re-apply power and observe for longer than 1 minute. 5. If failure remains, disconnect power, replace control, then go back to step 4. 1. Same corrective action as for other F3 codes, with the exception that the warming drawer resistance value at room temperature is approx. 100k Ω.

Door switches do not agree

1. Disconnect power from unit. 2. Check wires and connectors from control to door switch, then from door switch to control. 3. If no damage to wires or connector, replace door switch. 4. Re-apply power. 5. Press CANCEL PROGRAM and start the clean mode, and observe for one minute to ensure that operation is normal.

Door latch not operating

1. Verify error code by pressing and holding CANCEL/OFF key for 5 seconds. Momentarily (less than 5 sec.) press CANCEL key again to remove error code display. 2. Program and start the Clean mode. Observe to see if door locks. If it does not, inspect the locking mechanism from the solenoid to the latch pawl and door to find the cause of the problem. If the door is not locking, then 1 minute from the start of the Clean, the F5 E1 code will again be displayed. Press CANCEL key to remove error code display. 3. Once any mechanical problems with the latch mechanism have been corrected, program and start a Clean cycle (after, if necessary, clearing F5 E1 error code) to ensure proper operation of the door lock. Immediately cancel the Clean mode to observe proper operation of door unlock.
