Microwave turns on and counts down but won't heat up/cook

I have a microwave Emerson Model MW8117W.

It's only 2 years old.

It turns on and when you press cook it counts down, but doesn't heat up, plate doesn't turn, and nothing gets cooked.

Please HELP!!

    Microwave turns on and timer works but it won't cook and the plate doesn't turn. The fuse is fine. I can't figure it out!

Ok just figured this out! It is a problem with the alignment on the lower door switch. I took the cabinet off and lifted up on the door switch slightly and voila! It works. You could probably fix this without taking it apart, just lift up on the door ever so slightly. I hope this works for you.

    Oh my gosh! So simple! We were ready to toss it, but I just pressed upward on the door (1/16 inch, maybe?) and it started working again. Thank you!!!

For others with similar situation- I ran into this and fixed this with replacing 1 of the 2 door switches. I found someone who had the same unit and problem and he explained the whole resolution.

I ordered 2 of these switches incase the other went at some point. Had to widen the connectors to fit the replacement part, but it works fine. It is simply a failure on a moving part that gets used everytime the door opens and closes. So when it fails the switch does not close the circuit and the microwave senses the door is not shut and will not work properly.

I was having the same problem and it turned out the door was just misaligned. I pulled up on the door until there was a click and then it worked fine.

Emerson model MW8117W Microvave

If the microwave is rotating & the light is on, then the door switches have been satisfied. Some times the connections to the magnetron get crystalized. I have repaired mine just by pulling the leads to the magnetron on and off a couple of times, When testing always have the microwave loaded with at least a glass of water. And be careful because the capacitor in the microwaves hold a charge. Short out and drain the capacitor by touching both termnals with a metal objest like a screwdriver. Or unplug the leads on the capacitor befor beginning the repairs.

Can't use the microwave at all

you have either a bad keypad or control board.

If you have operation of some buttons and not others its the keypad. if you have no operation out of the buttons at all you have a bad control board.

If you turn your microwave on and it sets and the timer counts down you have a bad interlock switch..

please let me know exactly what your microwave does when you set the cook time
