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.
Repair was quite easy, as long as you have the instructions for removing the door. The screws that hold the bottom of the door to the fixed hinge are placed into the side of the hinge assembly after removal; this holds the door at a 45 degree angle for easy removal. After that, just place the door on a flat surface and dismantle the door from the inside. The inner glass is contained in a metal frame with another piece of glass; this frame comes apart easily using the clips in each side. The door assembles easily after the glass is replaced; just take your time and give yourself enough room to lay out the parts as you go. Good luck!
