First i shut off the power since this is an electric cook top/range. I then removed the knob and the two screws that hold the burner switch in place. I removed the wires one at a time and connected each to the new switch. I then reattached the screws to the switch. The most difficult part to me was breaking off the switch stem at the right level. I got that done and finally selected the appropriate adapter for the stem/knob fit.
lifted hood top unscrewed 4 small screws opening lid to switch housing took out 2 small screws that held the switch and then transfered wires to new switch replaced new switch with 2 new screws and back to working again walla! Time spent less than 30 minutes very simple as the instructions were very self explainatory.
I reviewed the schematic. Removed the outer casing. Pulled out the existing wires and replaced them exactly on the new switch. Snipped out off the control stem to match the others. There was a small metal piece on the old stem which holds on the knob. I removed it from the old stem and put it on the new stem and Eureka.
