The Microwave was completely dead and wouldn't run, light up or anything.
I followed an old appliance repair forums post from 2008 that discussed this exact common issue with this LG model. It took me quite a while to find the info. Then I used the schematic diagrams on your website to find where the part was located inside the microwave. I removed the outer cover. I tested all components including the thermostat for continuity with a multimeter. I discovered there wasn't any continuity in the thermostat so ordered the part and replaced it. Everything works like a charm! Thanks for the great, fast service.

Microwave fan would come on when door open. Timer and unit would not switch on.
I looked up my problem on the internet and found a very helpful video. Microwave on video was different brand but the internals and methods were very much the same. The video made it simple and easy to fix. Found the replacement switch on the LG parts site and ordered. Two different switch types. One with red switch, the other green. Part was $7.28. Saved a bundle in service costs. Here is the repair video.
