PF alarm appeared on display. Noticed clicking when cord was moved. Had arced for some time and melted original block. New part slightly different. Only has 3 lugs, old one had six. Stack using washers provided. Take note of colors before disassembly. Use caution while working through access opening. The edges are sharp. Only tools needed are phillips screwdriver, deep socket for lug nuts. Nut driver optional. Hope this is helpful.
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.
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 .
