The ICM271 Fan Control Center is a solid state control designed and engineered for the replacement market. The ICM271 is designed specifically to replace the Carrier/BDP Gas Furnace Control Centers that have been used in new equipment for many years. The ICM271 is an exact replacement requiring no modifications to the original wiring or to the appliance's sheet metal.
ICM offers low cost, direct wire for wire replacement fan blower controls for many popular OEM models. The fan blower controls monitors safety switches, provides on and off delays and controls the speed of the fan in heat pumps, air conditioners and forced air systems according to the logic of the original board.
