I watched a video on how to disassemble a GE cooktop. This involved shutting off the circuit breaker, propping the cooktop up above the counter, unscrewing the ceramic cooktop (I had to drill out one of the screws which had corroded), using a putty knife to break the glue seal all the way around, and separating the cooktop from the base. Breaking the glue/tape seal was a real pain -- I'm not sure why they chose to build them this way. The next hurdle was figuring out the wiring, since the new part was labelled differently and the schematic in my cooktop had different-colored wires than the unit itself. I managed to figure it out using the schematic and tracing where the wires went. The new switch worked fine and reassembly was relatively easy.
