The 6in burner would go to max heat regardless of the setting.

Un screwed the two screws in the downdraft section enough to release the unit that holds the surface burner controls.Then removed the control nob, unscrewed the two screws that holds the switch in the unit, removed the wires, making sure the color of the wires were placed on the same contact point. Put it back together and it worked
