James W Spring Valley , CA March 09, 2015 Two of my infinity switches quit working I call appliance parts pros and spoke with the customer representative. they were able to look up the correct parts from the parts catalog and shipped the part out to me. I took of the cook top and replaced the parts. I always ensure that I turn off the main power at the circuit breaker bot before I do any of this work. It took about an 2 hours to remove and install the new switches 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 1-2 hours
