Replaced dual infinite switch with new one from AppliancePartsPros. Part was exactly the same as the one in our range.

Had to go through the opening for the control knob. A professional probably would have known a better way to do it, but at least the job was completed - and at a small fraction of the cost of hiring that professional...
