F5 – E0 F5 – E1 F5 – E2 F5 – E5 F5 – E6 F5 – E7	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.
