LMV1831SB LG Microwave - Instructions

very simple

Initial failure of over range microwave Aug 3rd. Control Panel worked but no heat. Took to local LG authoriaed local repair place. They fixed it quickly and we re-installed it. Worked fine for 2 months then had similar failure again. Agaim took to same authorized repairer. They kept unit for 3 months but finally concluded theu could not fix it and suggested we contact LG for a partial refund. When they tested the unit during re-assembly in my presence, there was a blue flash and the fuse blew. Since we had built a custom tile mural back splash around this unit, I brought it home, ordered a number of time delay fuses new capacitor and two new high voltage diodes. However, using my Fluke DMM, I checked the existing capacitor and high voltage diode and they checked OK so I just replaced the time delay fuse. The high voltage transformer leads had 2 possible ways to connect to capacitor and diode. Tried one way, plugged unit in and turned it on, and immediatly blew the fuse. Replaced the fuse and reversed the high voltage transformer connections,amd turned unit pn, and it worked perfectly. Since we had experienced several power failures during the time of the original failure, the repairer concluded that power spikes might be at fault, so I also purchased a TrippLite ISOBAR4ULTRA 3300 Joule surge protector between wall outlet and microwave, and re-installed over range. It has worked perfectly since.

1. Removed unit from the cabinet. (2 screws). 2. Remove the outer microwave metal shell. (10 screws). 3. Locate and remove part. (3 screws). 4. Install new part and replace all screws. 5. Install unit back into cabinet. So easy. I will share this site with all of my friends.

Received my replacement Tray,Glass in only 2 days. Opened it and placed it in the Microwave. Yep, it was that easy!

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.

First we had to pop off the plastic frame on the inside of door. We were a little worried about that. But once we got a screw driver in and started loosining the frame it came easy. After that it was just 1, 2, 3, and done..

Took the tray out of the padded box, and put tray in microwave. That easy, no tools required.

removed the inner seal around the door (start at the bottom and work up and around--carefully!) this allowed access to the screws and simply replaced the handle.
