I first removed the top plate above the microwave door (3 screws), then I removed the plate containing the buttons and clock. The microwave has 3 relay switches and they are in a little holder. The holder was too difficult to remove so I just removed the bottom switch and replaced. The microwave started right up.
Part arrived in one day. Old part snapped right out and new snapped right in. One minute repair with no more sparking and no need to invest in a new microwave... which is what I thought I was going to have to do.
was told buy a repair person to check the door micro switches as it was a common problem. removed the top plastic air grill to get access to the screw that holds in place the control cover. After unplugging the unit, i took out the (2) screws that held in the switches and removed them (3). One switch was a bit melted so i tested it with a 12 volt battery and it was bad. Ordered a new one from Part select and got it fast . Works great .
