Bob Davis for Model Number LMVM2055ST Hello, Our microwave timer works, clock works but when we enter a cook time and hit start, the microwave will not start . . . just the cook time starts its countdown. I ordered all three micro switches from you and replaced all three. No change in the no start issue. I have a new magnatron and a time delay fuse in my cart. Just wanted to check with you to get your expert opinion on the likely cause of my issue before ordering more parts. Thanking you in advance for your prompt response . . . Bob Davis

This would most likely be the control board that is at fault since the door switches have been replaced. Read More... Answered by AppliancePartsPros.com | Monday, March 6, 2023
