We had to replace the infinity switch for the problematic burner. I was really impressed that Appliance Parts Pros had the part in stock, actually shipped it one hour after I submitted the online order late in the afternoon, and it was on my doorstep at 10:30 the next morning, even though I selected standard shipping of two to five days. Outstanding experience! Repair was as simple as removing a panel, removing the mounting screws, disconnecting the wiring connector plug, connecting the plug to the new part and putting everything back together in reverse order.
