Kenmore Radiant Ele Cooktop (by 2 users)

They have a thermal overload resistor in the burner itself and they have a propensity to burn out, making it either all off or on, or it could be the infinite switch. I would check the resistor first. All the way cool you should get close to no resistance. Heat it up with a blow dryer and there should be more resistance. For the infinite switch, you will have to check resistance across the leads that correspond to each pinout as to what it goes to. You can find this out by backtracing the wire to each terminal on the block. Replacement of either part is the only option, there are no safe alternatives to repair them. Hope this helps. BTW, you can go here for parts.
