Replaced the infinity switch. My appliance is a whirlpool glass cooktop mounted in an island - not a range/cooktop combo. There is no video for replacing the infinity switch on appliancepartpros.com for my particular appliance, but there is one for a normal range/cooktop combination. I wasted a little time because I thought the one way to access the switch was from below, so I removed a burner until and partially removed a drip pan before I realized that getting to the switches was as easy as removing the screws concealed under all of the knobs then lifting up the glass plate they are set in. New switch has the same markings as the old switch, but label the wires before swapping them out anyway just to be safe. Easy job, appliancepartspros.com has saved me a lot of money this year!
