Repair is simple as long as you TURN OFF THE CIRCUIT BREAKER first. After that, take off the cover over the switches (pull knobs off, remove 2 screws and lift off the cover), pull the bad switch straight up off the gas valve, pull the two wires off the switch, plug them back onto the new switch, place it back over the gas valve stem, reassimble the cover and knobs, turn back on the circuit breaker, and verify that ignition switch works. Not a hard repair. (HINT: while you are waiting on the replacement part, you can light the bad burner by turning on the opposite burner ignition switch and using that "spark" to light the other burner.)
