LWS3081ST LG - Instructions

Go onto youtube, such as https://www.youtube.com/watch?v=-ITkrwhDNMQ and watch similar videos for DYI. The process is very similar to other models.

Once the door is removed, place oven door on a towel or soft place so it does not scratch the door. Unscrew the screws and make sure you notice where each screw goes, so you know the process of where each screw goes when you re-assemble.

Once the inner cover is removed, remove the insulation, too so you don't damage it. Use Wet/Dry Shop Vac to clean the shattered glass. (WORD OF ADVICE: I did not remove the insulation and the suction of the Shop Vac removed part of the insulation, so now instead of a quick turn around repair turns into a few weeks repair, because the insulation is on back order 10-14 days from the supplier. DON"T MAKE THE SAME MISTAKE!)

Once the glass has been removed, the new inner glass is replaced, begin by re-assemble the oven door with the correct screws and attached the oven door to the range.

Hope this helps

Replace missing vent. Pretty well straight forward. Not complicated at all. Three screws is all it took, done.

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.

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.
