Tripped circuit breaker. Disconnected hard wiring under cabinet. Lifted cooktop and carried out to workbench. Removed screws holding glass top and lifted off. Removed screws holding bottom case. Removed two screws holding switch in place. Turned the element section over and removed the old switch and replaced with the new. My problem: The numbers on the new switch are placed such that they do not exactly indicate which connection goes where. An instruction sheet comes with the new switch correlating the old numbers to the new. My old switch, you guessed it, did not match those number in the instructions. Went to the other dual element switch and, with some difficulty, figured out how to hook it up. Dropped back in cabinet, tested, working fine!
