Jeff S Hope , IN July 11, 2016 Microwave not working; would not heat Replaced Magnetron and diode. Fixed problem and microwave workso again. Very time consuming because of microwave/oven built-in combo. Not easy to get to parts that needed to be replaced. Still cheaper to repair than to replace.

Michael L Minneapolis , MN November 30, 2016 Microwave stopped working it made a loud hum and smelled faintly of ozone I replaced the magnetron and diode. I don't know if the diode was bad, but since the majority of the work was taking the case apart, I figured it was easier to do it at the same time as the magnetron. The replacement magnetron I received was dented at the emitter end, but seems to work fine. It was a bit intimidating to work on a microwave with all the warning stickers on the cabinet, but the replacement went smoothly - the biggest difficulty was determining how to remove the panels of the case (it is a combination oven/microwave oven) without disassembling the entire unit.

Antonio F Miami , FL June 08, 2018 Appliance: Model KEMC378KSSO Humming sound and burnt smell I measured the resistance between the two connectors on the magnetron: should be close to zero ohms and it was. I measured between the same connectors and the metal case: should be mega ohms, it was 15k ohms. That is a bad, partly shorted unit. I also checked the resistance of the thermal cut off, which should be zero but was 10 ohms so I replaced. The HV diode is checked with a 9 V battery (YouTube checking microwave HV diode) and it too was bad. Make sure to take pictures as you disassemble the unit as I had a few leftover screws. Unit is working great now. Read More... 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes Tools: Screwdrivers
