All Installation Instructions for LG Microwave LMHM2017ST

food does not get hot, carousel did not turn, all other indicators worked

Read the troubleshooting section on this site. Figured it was an interlock problem because the food was not getting hot (magentron not turning on) and the carousel was not turning. Did not think both the carousel motor and magnetron failed at same time, thus indicated an interlock problem. The interlock switches are actuated by the door latch. Replaced the assembly locker piece with all three switches (only a $20 dollar part) and microwave was fully operational again. Wife and kids think I am a hero.

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!

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.
