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.
