Mw will not cook. When we push buttons to start you hear a click but oven does not come on, the timer counts down like it is on. All buttons on control panel work. It acts like it is working but isn't. Light and fan works.

The part I'm looking for is, what I would call the "start switch". When the door is being closed, the lower Latch pushes against a lever, which fell off. Guess it's part of the "start switch"? What part # would that be? Thank You Riff Tiff

No power to microwave. Replaced and tested both fuses, tested continuity for all switches and tested capacitor. Could it be the high voltage transformer or is it some other part? Thx.

Once the fuse is replaced, the microwave oven works fine for a while and then the fuse blows again. If I replace it again, it works fine again for a short period and blows the fuse again.

Microwave went through a cycle turning it self off. When closing the door it wanted to turn on but just humming only not the blower motor. The only key pad functions working are the light and exhaust. If it is the door switches can they be replaced without removing from the wall it is an above the stove model mounted to the cabinet. It may have been humming for 5 minutes before it was detected. Would this 5minutes damage anything having nothing inside it. There was a possible overheating smell coming from it.
