LMH2235ST LG - Instructions

We had made this determination with the help of a repairman on the phone. I ordered the part and waited for it. It was stuck in West Virginia. After several days after it was expected a repairman fixed my range to the tune of $168. It should have cost $30 (the cost of the part and shipping).
Unfortunately I probably won't order from PartSelect again.

removed MW disassembled the fan slide and installed.

I unscrewed the light cover, removed the burned out light bulb and replaced it with one I ordered on Partselect.com. It was very easy.

unplug the unit then pull down , lot of screws are on top. open the cover . you could see the parts that need to replace on the right hand side (heavy side). disconnect wires then test the parts that need to replace by a tester to make sure that it's really broke .then unscrew part and replace .

Ordered the switches from Partselect, arrive in two days. Had trouble removing the plastic connectors from the old switch terminals, one of the plastic protectors broke, but was able to reuse it. It took a little figuring out how to remove the existing switches. Must push in a tab and rotate the switch on a little pin, then remove. Must be careful not to break the plastic tabs holding the switches in place. Replaced all (3) switches at the same time. All in all it was pretty easy.

really easy

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.
