Scott S Charlotte , NC June 20, 2017 Microwave oven was not heating 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. Reassembled the unit and tested it and this time it worked. With the excellent 365 day policy from Appliance Pro Parts you can return the unneeded parts.

William H Greensboro , NC July 26, 2015 Magnetron and high voltage diode were shot Hardest part was pulling the unit as it was a microwave / oven combo (Kenmore). Found install instructions online and just worked backwards. Removed side panel and vent shroud. Discharged the capacitor (VERY IMPORTANT- don't fry yourself). Removed magnetron, diode, and capacitor, marking the leads for reinstall. Tested all three parts with ohmmeter to find the culprits; also tested transformer (was OK). APP got me my parts within three days. Replaced parts in reverse order of removal, replaced panel and shroud and reinstalled unit. All is fine now. Google "microwave oven repair" to find YouTube diagnostic instructions; worked for me!
