Re: fan - vent/heater (alexjungle)

pop the heater faceplate off.. unplug the rotary switch.. replace as needed.. or open it up and figure out which resistor is burned..done

Common problem, and no, it's not the switch. It's the resistor pack or the thermal fuse on the fan motor. Dead easy to replace. Just do a search for "resistor pack" on this forum.
