Do-It-Yourself Stories from Customers like You Our lg lmv2031bd otr microwave started making scraping and clunking noises but continued to work fine otherwise   Russell S. • Moultonboro , NH • January 06, 2025

Looked online and found that someone had experienced the same issue and had replaced the cooling fan assembly for the magnetron. I ordered the parts for the assembly (motor, fan, and support), and replaced them and this fixed the problem. It took about 10 minutes to replace the parts, but lowering the unit and disassembly took around 45 minutes. The most difficult part was getting the outer sheet metal cover back on after the repair, as it has a bunch of clips on each front edge that need to... Read more

Do-It-Yourself Stories from Customers like You Microwave would not microwave   Richard E. • Cape Coral , FL • January 05, 2020

Replaced the Humidity sensor, Thermistor and door switches. I replaced these thinking the problem was one of the items but didn't want to trial and error one part at a time. Plus the cost was reasonable so if these didn't help I wasn't out a lot of money. I sense the door switch was the problem. Replaced all items and the microwave works great.

My son told me that almost all the microwave ovens that came into the repair center he worked at, 15 years ago, had a defective magnetron. I ordered a magnetron, and sat back until one shipped. The one that came, the first time, was in a small factory cardboard box, which was in a large bubble-pak Fedex envelope; which didn't show any signs of abuse. Inside, however, the factory box was beat up. Removing the magnetron, I noticed that the socket, as well as its' pins, was bent, and loose in the... Read more
