Consumer fuses are normally on the rear where the power lead goes in. It is a small screw cap or a long pull out fuse with a small notch in the end.

The thermal fuses and the ceramic fuse might of had blown and need to be replaced. It could also be that door switch and the door latch are not working. The plug could be bad.

The most likely reason is a door safety micro-switch has failed or moved out of adjustment.
