IF YOU NEED TO REPLACE ANY OF THE ABOVE CIRCUIT BOARDS PAY ATTENTION! |
|||||
For Suburban® # 232613 or Atwood® / Hydro Flame® # 37857 fan control boards use: Dinosaur Electronics FAN 50 Plus board. There may be other board numbers that are not documented here that will also apply to this bulletin. The FAN 50 Plus board works in furnaces with Suburban’s® and HydroFlames® fan control feature, and can also be used to implement the fan control feature in most 12 VDC DSI Furnaces* *Note: Fan control boards should not be used in DuoTherm® 900 series furnaces that have the thermostat in the ground circuit. DuoTherm® furnaces can be rewired to move the thermostat from the ground side of the circtuit to the positive side of the circuit so that the Fan control features of the Fan control or FAN 50 Plus board can be used.
