OEM Carrier Fan Timer Control Board 20054502 for Model G2RR050A12

This is the factory OEM fan timer control board (part #20054502) for the Carrier G2RR050A12 gas furnace. The integrated fan control (IFC) board is the brain of your furnace — it sequences the inducer motor, igniter, gas valve, and blower fan in precise timed stages. When this board fails, symptoms can include the furnace locking out after ignition attempts, the blower fan running continuously or not at all, erratic cycling, or a complete no-heat condition with no apparent cause in other components.
