I pulled my unit out of the wall and noticed that the insulation around the top broiler element was a bit brown. Closer inspection revealed that the element had shorted somehow to the oven itself and caused the element to become non-functional. I tried measuring the resistance first, and it was within typical values for the other elements, but I decided to replace the element anyway.
I ordered from PD and the part arrived just a few days letter by regular shipping. I undid the screws holding in the element, undid the wire connectors and replaced the broken element with the new one. The element worked like a charm and I was back in business for cooking.
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.
Turned power off at electrical panel. Pulled oven away from wall. Removed back cover (6 screws), then unplugged wires from old receptacle. I had to pull the squeeze clips backwards & break them to remove the old receptacle - couldn't squeeze them enough to remove them otherwise. The old receptacle came out through the inside of the oven, and the new one snapped in easily from inside the oven as well. Replaced wiring, installed new bulb, restored power & tested. Replaced back cover. Good time to vacuum under/behind where the oven usually lives before sliding it back to the wall.
