Door switches do not agree (condition exists when door switch is closed indicating an open door, and latch switch is closed indicating a locked door)

Self clean latch will not lock

Latch during CLEAN error

Self clean temperature not reached within 45 minutes.

Door is open, but latch is locked

Self clean latch will not unlock

1. If door latched:
A. Disconnect power from unit
B. Check wires and connectors from control to door switch, then from door switch to control. If no damage to wires and all connectors okay, proceed to step C.
C. Replace door switch latched:
D. Re-apply power
E. Press and hold any key down for 1 minute to clear F5 failure code from memory. F2 will appear. Press CANCEL and observe for 1 minute to ensure operation is correct

2. If door not latched:
A. Disconnect power from unit
B. Check wires and connectors from control to latch switch, then from latch switch to control. If no damage to wires and all connectors okay, proceed to step C.
C. Repeat steps A and B for door switch

3. Measure door switch (door open = switch open small low voltage terminals). Replace switch if defective

4. Measure latch switch (unlatch = switch open, CAUTION – oven light contacts are closed). Replace switch if defective

5. If corrections are made in any step, reconnect power to control. Press and hold any key for 1 minute to clear R failure code from memory. F2 will appear. Press CANCEL and observe for 1 minute to ensure operation is correct
