Christopher H Fernley , NV March 25, 2021 Switch caved in while replacing the knob. Grounding out the contacts and melting the connections. Unplugged oven, removed 4 nuts off the back upper panel, took 2 screws off the front under where the knob plugs in, unplugged connection wires from old switch and replaced in the same location on the new one, then reassembled in reverse order. 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
