Replaced all four switches. One of them had dangling terminals from over heating. Had to replace two wire terminals on the wire because of overheating. Couldn't tighten terminals because they weakened from the heat. so replaced them. Not a major job to replace. But you just change one wire at a time and there should be no problem. Special Thanks to Appliancepartspro.... They get the items right out to you quickly, (Next Day for me), and they were cheaper than my local appliance dealers.
