Range Surface Element Control Switch
The surface control switch on your range controls and sends voltage to the surface element. Signs of a bad surface control switch are, the surface element may stay at high heat.
The surface element may stay at high heat no matter what setting you have the selector knob on the switch set at. You might not be able to turn the surface
element on or off at all. If the surface element is acting erratically, the surface element control switch, also known as the infinite control switch, is the main culprit and should be replaced.
