Microwave won't stop running or starts when door closes? A faulty door switch is likely the cause. This safety switch is a 45-minute DIY fix.
The first symptom was our microwave would continue to run after the time was up. The light would go out, the turn table would stop but you could still hear the microwave running and whatever was in it would continue to cook. The only way to stop it was to open the door. It was intermittent at first but eventually it would always run no matter what as long as the door was closed. Several other posts referenced these switches as the problem. I just replaced both and problem gone. It turns out... Read more
Microwave won't start or heat but light works and timer counts down? A faulty monitor switch is often the cause. DIY repair typically under 30 minutes.
Microwave not heating but lights and timer work? The high voltage diode converts AC to DC for the magnetron. DIY repair in 1-2 hours with basic tools.
Wife let me know the microwave was making grinding noise while I was in garage fixing her car starter, never a dull moment. Further questioning she also said it wan't heating the food. Due to being an odd sized built in $$ unit I had to have repaired. I was getting quotes in the $4-500 range for just the magnetron. I was pretty confident the magnetron was the issue and also ordered a new capacitor and diode since I was going to be in there and a lot of money ahead repairing myself. About... Read more

If your microwave runs but won't heat food or makes grinding noises, the magnetron has likely failed. Moderate DIY repair requiring capacitor discharge.
Microwave not heating or humming loudly? The high-voltage diode converts AC to DC for the magnetron. Repair takes 30-45 minutes with basic tools.
I replaced both the Magnetron and the high voltage diode. I now have a fully functional microwave. I received the parts on time and the quality was good. I would use appliance parts pro's again. Read more
Microwave not heating? A failed high-voltage capacitor prevents the magnetron from working. Requires discharging and wall unit removal to replace.
I ordered the capacitor, diode, and magnetron in hopes that I would be able to complete the repair using the less expensive parts. I first removed the oven from the wall and then I removed the metal housing to access the internal parts. I discharged the capacitor using a pair of insulated needle nose pliers. Then I changed out the diode and the capacitor and reassembled the unit and tested it. It still did not heat so I disassembled the unit again and replaced the magnetron this time.... Read more

Microwave shuts down during use? This thermal cutoff thermostat prevents overheating by interrupting power when temperatures exceed safe limits.
My daughter that she turned timer on but hit cook with nothing in the microwave. I was able to figure it was one of the four thermal cutoffs. It was obvious which one literally fried. Replaced that one worked like it was new. Took a lot of photos while dismantling and labeled the screws. Wasn't that hard just be careful of the capacitor Read more
Microwave not heating but lights and fan work? Buzzing noise when running? The magnetron generates microwaves to cook food. Moderate DIY repair difficulty.
Contacted a AppliancepartsPros tech. Told him what was wrong with my GE Microwave with range hood which is 24 years old. After trying to cook popcorn it made a buzzing noise and didn't heat food. He told me it was the magnetron. I ordered it. Received it approximately 3 days later. I installed it and it was back in perfect working order. I am happy. Saves me from purchasing a new microwave for over the stove which would be very expensive. Thank you AppliancePartsPros. Mike. Read more
Microwave won't heat or shuts off during use? This magnetron thermostat senses temperature and controls heating. Moderate DIY fix with basic tools.
I replaced the sensor including the slip on connectors. The diagnosis was made by visually observing the burned connector and sensor and then confirming that the sensor had no continuity using an ohm meter. Read more
