Tommy W Conway , AR January 18, 2020 Burner would run on high heat regardless of setting The controller (knob) had a short, we could hear arcing, then the burner would have runaway heat. We changed the controller and that stopped the arcing but did not stop the runaway heat. I will replace the heat sensor and burner next.
