Microwave not heating but runs? Replace the magnetron to restore cooking power. Intermediate DIY repair taking 1-2 hours with proper safety steps.
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
This molded resin cover is a protective plastic shield used inside the microwave. It helps protect internal components and ducting from splatter and debris and restores a secure, finished fit when the original cover is cracked or missing. What it does:
After researching on the internet, I decided replacing the wave guide cover would be much cheaper than replacing the microwave. Plus I couldn't even find one that worked with the existing trim kit. Had a bit of difficulty removing the old cover, but the folks at Appliance Parts Pro answered my email question within 24 hours. I received the replacement part a day or so later.

This rivet assembly is a direct-replacement fastening piece used to secure appliance panels and components, restoring a stable, rattle-free fit and preventing movement caused by worn or broken rivets. What it does:
I replaced the stirrer fan cover and fan, which had some carbon and slight burn marks on it. It was difficult to remove the fan cover as it did not rotate. I had to pry it off with a flat blade screwdriver, breaking the plastic tabs on the cover (which was being discarded anyway). I then cleaned any visible carbon deposits and replaced the cover and fan, using the old stirrer fan holder as it appeared OK. However, I was unable to rotate the cover into the locked position so I could not insert... 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.
