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 unpluged the machine. Pried out the old switch with the tip of a screw driver. Pried off the connectors, there was not enough extra wire for me to connect the new switch through the front of the machine. I pushed the new switch in place. Using the screw driver I carefully pried open the top front of the machine { there were 2 plastic spring clips securing the top}. I placed a wash bucket on the drum to hold the top open , connected the 2 connectors to the switch and snapped top back in place.
