Something sparked and the microwave stopped. I thought something happened inside. No problem there but would not work. My husband flipped the breaker and it came back on. I hit the 4 key again and it operated for 3 seconds and quit for good. Could this be a blown fuse or is it more likely a bad key pad?
Answer Hello Sue,
This is probably a bad fuse. This could have been caused by a number of things in the unit but the most common cause is a bad door switch. There are three of these and should all be replaced at the same time. To prevent the door switches from being a problem, never open the door when the unit is running. Always hit the stop/pause button before opening the door.
