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 called a repair place. They charged $54 to diagnose, (said it needed a new latch motor) then wanted $220 to complete the repair. I checked online prices and did it myself for about 15 minutes work and the latch motor itself ($44?).
Was necessary to uplug the range, pull it away from the wall and remove the back panel sheet metal, then 3 screws that mount the motor. Replace motor, reattach sheet metal. Plug in. Done. Ready to bake cookies.
