Fantastic Fan Control Moisture Problem
In my '06 Dutch Star I had to replace the Fantastic Fan control unit mounted on the outside wall of the bathroom earlier this year. The folks at Fantastic Fan sent me a replacement control board at no charge....great product and customer support.
The customer service tech I spoke with said there are moisture problems from condensation forming on the printed circuit board in units that have the control mounted on an outside wall in the bathroom. Here in NC this past Wednesday night temperature dropped to 30 degrees. By Saturday mid-afternoon the temperature was 76 degrees. When I tried to turn on the fan in the bathroom for ventilation it would not work.
Two problems: the vent lid was stuck, (would not open) and the control on/off switch was not working properly. When I removed the switch from its housing the back of the switch was dripping wet with moisture, however, the insulation inside the wall was perfectly dry. I dried the back of the circuit board and forced the lid open and the fan worked as it was designed to.
Has anyone else had this condensation moisture problem with control units mounted on an outside wall and if so what did you do to eliminate it?
