I first read where someone had the same problem. Their solution was a burned-out fuse. I ordered a new fuse...installed it and that did not solve my problem. I revisted PartSelect and read how Marla (from Arlington, TX)solved her problem. I purchased a secondary switch and when it arrived, I made a copy of Marla's instructions and followed them to the letter. I installed the new secondary switch into the secondary space, put everything back together and the oven STILL DID NOT WORK. I had to take the latching panel apart again and test each switch to see if there was another bad one. I found that the third switch was burned out. So I took the new switch out of the second slot and installed it into the third slot. I tested the switches before reinstalling the latching panel. This time everything worked. So I put everything back together, reinstalled the microwave on the wall, tested it again, and everything worked perfectly.

With this model, you must remove the outer covering. Don't try to access the display unit from the front like I've seen in some other GE microwave videos. After removing the outer covering, the switches are easy to replace. They are very visible and easy to get to without taking any other parts off. You will see the door switches just behind the display board. Remove the switch and then remove the connecting wires to ensure you don't inadvertently brake a wire. You will need a tamper resistant star bit to remove 3 or 4 screws from the back panel. All other screws are philips head. I went ahead and replaced both switches (yes...there are two of them) and works like a charm. I saved an $800 microwave for less than $60 and know what to do if it happens again. Appears to be a common problem on this model. Thanks for others making a post...It saved me time and money reading others remarks. Good luck!

i unplugged the unit,unscrewed the outer shell so that all the wiring and internal components were visible.starting at the first of three micro switches i removed the slip on terminals installed the alligator clips too the wires so the switch would now be bypassed.i made sure the wires and clips were not touching anything plugged unit in and it worked.i then installed the new switch and closed up the outer shell

PER YOUR INSTRUCTION

remov cover to check voltage and found problem at the interlock switch ohm the switch and found it was open replace both switches it work fine now

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.

First I had to accept the fact that the unit was designed to keep non-professional people from doing any repairs. The switch was installed in such a manner that I had to break the mounting to remove the switch, then drill a hole in the mounting to secure the new switch in place.

Problem was due to a faulty door switch. Replaced with a new switch and the microwave now works fine! Only thing that was tricky was that LG uses the hex screws with a peg in the middle to keep the microwave cover on. Had to use a small screwdriver and pliers (on the screwdriver) to unscrew the screws.

Easy, and the microwave still doesn't work.

Checked all sensors with a multi-meter, found the thermostat to be the problem, no continuity.
