Probably a faulty door switch has blown the microwave fuse. If you are lucky.

The main fuse in the microwave oven has blown, usually caused by one or two defective door switches.

sounds like the magnetronis bad

Hi! the problem you have mentioned indicates that your microwave magnetron is not working. check for busted fuses.

check the fuse on the microwave. if its busted, something shorted out in the oven that tripps off your breaker. it could be your inverter.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose conneciton on the control unit circuit board
- bad magnetron or other high voltage part
