JMC9158AAQ - Instructions

All the electrics worked on Amana microwave EXCEPT for the cooking function. Inspected the control board and found the upper switch on the door interlock was burnt. Installed new switch in minutes and everything now works fine. Unfortunately, had to purchase expensive two switch "kit" although only one switch was kaput. PartsSelect mailing was SUPER fast. Thanks for looking, Scott

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.

You have to remove the cover which in my case was a little more difficult because the unit is wall mounted and has a frame around it. That was the hard part. Once the mounting frame was removed, you can remove the cover and the light bulb is on the top right side of the unit. One screw removes it and the new one pops right in. Put the case back on reinstall it in the wall and voila...piece of cake.

you will a security socket T20. this unit was installed over oven, remove trim cover,remove screws holding unit in place,I used a helper to get the unit out, once out you have to remove all the screws holding the cover on,on two of the corners they use a security hex screw so you need a special socket for that. remove the door latch switch,take your time or you will break tab holding switch in. ask me how I know.but super glued broke piece in place and plugged wire back in.the new latch may have a second pin but look at old one and plug wires in the same way.the light bulb does not screw out so I had to purchase the entire unit.total cost under a $100.00 to do repair.
