OEM Carrier Integrated Furnace Control Board HK42FZ013 for Model PG9MAB036040ACSA

This OEM Carrier integrated furnace control board (IFC) is the factory-specified replacement for the Carrier PG9MAB036040ACSA gas furnace. The control board is the brain of your furnace — it sequences every critical operation including inducer startup, hot surface ignition, gas valve timing, blower motor staging, and system fault monitoring. When this board fails, you may experience a furnace that won't heat, trips into hard lockout after ignition attempts, runs the inducer but never fires, or shows erratic blower behavior. Diagnostic LED fault codes on the board itself help pinpoint the failure before and after replacement.
