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!!

    Woo hoo! This worked great. I used some epoxy putty to put a small plastic clip, 1/16th “, on the bottom inner door frame to raise the door when it closes and make a permanent fix.

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!!!

Thanks for the great tip! Ours started acting up today and was sporadic—sometimes it worked and sometimes nothing but the light and countdown worked. Turns out it was due to door sag—pushing up when you closed it made it work consistently—what a relief with Thanksgiving right around the corner!

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.

http://www.nouserserviceableparts.com/2011/03/31/fixing-a-emerson-mw8992sb/


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.

Emmerson turns on and counts down but no cooking happens.

If your Emerson microwave is turning on and counting down but not actually cooking or heating the food, there could be a few potential causes for this issue. Here are some steps you can take to troubleshoot the problem:
  1. Check Power Levels: Make sure the microwave's power level is set to the desired level for cooking. Some microwaves have adjustable power settings, and if it's set too low, it may appear that the microwave is running but not cooking properly.
  2. Door Interlock Switches: Microwaves are equipped with safety interlock switches that prevent the microwave from operating when the door is open. If any of these switches are malfunctioning or not engaging properly, it could prevent the microwave from cooking. Ensure that the door is fully closed and the switches are working as intended.
  3. Turntable and Support: If your microwave has a turntable, make sure it's properly seated on its support and able to rotate freely. If the turntable is not turning, it could result in uneven cooking or no cooking at all.
  4. Magnetron Malfunction: The magnetron is the component responsible for generating microwave energy for cooking. If the magnetron is faulty or not functioning properly, the microwave may appear to operate but won't actually heat the food. A malfunctioning magnetron usually requires professional repair or replacement.
  5. High Voltage Diode or Capacitor: The high voltage diode and capacitor work together to convert the high voltage output from the transformer into microwave energy. If either of these components is defective, it can prevent the microwave from cooking. Again, professional repair may be necessary.
  6. Control Board or Circuitry Issues: A malfunctioning control board or other electronic components could also lead to a situation where the microwave appears to operate normally but doesn't actually cook. If you suspect control board issues, it's best to contact a professional technician.
  7. User Manual: Double-check the user manual for any specific instructions or troubleshooting steps related to cooking issues. The manual may provide guidance on common problems and their solutions.
If you've checked these common issues and the microwave still isn't cooking, it's advisable to stop using it and contact Emerson customer support or a professional appliance technician for further diagnosis and repair. Microwaves contain high-voltage components that can be dangerous to work with, so it's important to prioritize safety and seek professional assistance if needed.

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
