OEM Carrier Integrated Furnace Control Board HK42FZ040 for Model PG95XAT60100CAAA

This is the genuine OEM Carrier Integrated Furnace Control Board (part number HK42FZ040), factory-specified for the Carrier PG95XAT60100CAAA 95% AFUE gas furnace. The IFC board is the operational brain of your furnace — it sequences every stage of the heating cycle, from inducer startup and hot surface ignition through gas valve firing, flame verification, and blower ramp-up. When it fails, symptoms range from hard lockout with a flashing fault code and no heat, to erratic short-cycling, blower that runs continuously, or a furnace that starts normally then shuts down mid-cycle. Replacing with a genuine OEM board restores factory-programmed timing, safety thresholds, and diagnostic fault code behavior that aftermarket boards often cannot fully replicate.
