Items were not getting heated up in the microwave,
I went to LG website enter model number and was given a list of parts that need to be replaced with a percentage of which part fails the most. I order micro switch PS3522738 which arrived and PS3529293 was backordered. I installed the one that arrived. The microwave worked briefly. I reordered and waited for both switches to arrive and installed both. The microwave still doesn't work.

Oven would not start when closing door.
Removed some cosmetic panels. Removed the assembly with micro switches. Examined the faulty switch by checking the clicking action of switch. Two others were ok by this method. Replaced the switch with new one. Works fine so far. Thanks to web site and YouTube videos.

Replacing top vent filter
Followed owners manual instructions to the letter: removed two top screws, opened the unit door so I could slide out the old filter. We don’t cook much at all in the unit, mostly just heating coffee and reheating leftovers. BUT! The top grill was pretty greasy and needed hot soapy water to clean, including in the depths of the top area. The whole process, especially the company website for part ID and purchase, was slick!

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.

First problem was removing the vent cover. There were four screws that were not obvious that held the cover on. Reinstalling the cover also proved to be difficult due to alignment problems. Once that was done, the second problem was removing the door. There is a small, almost invisible, latch that h

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.

microwave turn table not working
Removed the phillips screws from the base.

Using a # 10 secure driver, remove the motor. (I recommend obtaining a secure star driver set to be sure you have the right size)

Replace the spacer, which is a separate part from the motor.

Reinstall the spacer and motor.

Reinstall the bottom panel.

Enjoy!
