Gert V Sunnyvale , CA May 15, 2023 Appliance: Model KENMORE ELITE The microwave not turning on but light and timer working. Replaced the bottom door switch. There is a good YouTube video on how to safely work in the microwave because you have to discharge the magnetron. This Kenmore is an LG branded one. I ordered both door switches listed for my model, but I only needed 3B73362F (AP4437957). This one is apparently the most likely to fail. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
