I had used the covection broiler to cook a roast (which was cooked perfectly). I then microwaved 2 pototatoes. They weren't quick ccoked so I cooked for 2 more minutes, still not cooked, two more. I didn't notice anything but thought enough time had gone by, so checked and the unit did not have power. i thought I might have tripped the breaker, but my boyfriend checked and checked the fuse box. It isn't either of those.
Their is a chance that the power went out in the house. Also, chances are that it just broke.

The most common suspect here is a shorted high voltage capacitor, since you say it blew the fuse right after Start, but I would certainly suggest checking the door switches and door switch mounts first. Just be sure you installed the right fuse. It would be a The switch mounts seem to break at about this point in the life of these models.

This 59-second stop failure is due to a problem in one of the damper-related components, most likely the switch, but it may also be the motor or the damper door.
The damper is a door inside that opens or closes depending on cooking mode. If the controller thinks that the door is not in the right position, it will shut down the cook cycle.

The door switches go bad...little micro-switches. Check them for switching on and off. Some are closed when the door is open, some are open when the door is open. It could even be that the catch has moved out of adjustment. If that isn't the problem, you have to consider the brain board which is usually so expensive that the microwave is not worth fixing.
