OEM Carrier Integrated Furnace Control Board HK42FZ040 for Model PG95XAT60080CBAA

This is the genuine OEM Carrier Integrated Furnace Control (IFC) Board, part number HK42FZ040, factory-specified for the Carrier PG95XAT60080CBAA 95% AFUE two-stage gas furnace. The control board is the brain of your furnace — it sequences the inducer motor, igniter, gas valve, and blower fan while continuously monitoring safety switches and sensors. When this board fails, symptoms typically include a furnace that won't ignite, flashing fault codes on the LED diagnostic light, erratic or short-cycling behavior, or a unit that locks out entirely after repeated ignition attempts.
