I replaced the "infinite switch," behind the burner dial. I found the replacement part and ordered it from ApplicancePartsPros.com. It arrived in about three days. I watched the video on the Appliance Pros websit and followed instructions: I unplugged the unit, removed six screws (with a power screw driver) holding the back cover plate, removed the connection block and spade-connected wires from the old switch and put them on the posts on the new switch. I pulled off the knob of the old switch, removed two mounting screws, put in the new switch and mounted it with the two screws, removed a spring clip from the stem of the new switch to snap off a piece of the stem to match the depth of the knob, replaced the clip and the knob, replaced the back cover with the six screws, plugged in the stove, and tested it. It took 15 minutes.
