“Fan control knob for heat intermittently would only work on some speeds and gradually would not work at times. It would catch every once in awhile only on high, I could smell something hot, now it does not work at all. After looking behind the cover, the clips that hold the relay switch to the knob are melted, the relay switch is burned and the wire harness is melted.”
