Jaime I replaced one of these in my mother's Kenmore range about three years ago to fix this behavior where the burners would fire up to red hot despite being dialed in to a low setting. When I removed the old infinite switch it was charred and burned out. Replacing it fixed the problem then, but apparently its returned. I haven't yet inspected the switch but I suspect it burned out too, since the particular model of theirs has only one large burner, the other three being small, and therefore it gets used disproportionately compared to the other three. What's the average lifetime of one of these infinite switches. I'm ready to purchase another but don't want to invest in one should there be deeper issues to resolve. Thanks so much for this great website. ~Jaime
Answer Hello Jaime. There is no way of telling the average life of the switches. Some last for many years and some fail quickly. If the switch worked for 3 years, it most likely just burnt out from being used so much. Read More... Answered by AppliancePartsPros.com | Tuesday, February 4, 2014
