I have had about six of these switches. They perform as expected for some time but then either the fan control or the limit fails. Often the fan will not shut off. Other times the limit will not close. To have these occurrences over and over indicates design flaws that I expected would be corrected but so far that hasn't happened. I'm waiting to see how long this latest one lasts. The idea is good but the switch is terrible, awful, NG!JLR
