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.
Lifted stove top to disconnect burner wires in order to use stove until parts arrived. Remove a bunch of square drive screws to remove back panel from stove. Identify relay board and disconnect wire connectors from it then release several plastic clips and two screws holding board to oven. Install new board and connect wires, No other adjustments were required.
