Two of my infinity switches quit working James W. • Spring Valley, CA • March 09, 2015 My Repair & Advice 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 Was this review helpful to you?
