OEM Carrier Furnace Control Board HK42FZ013 for Model PG8JAA036045ACJA

This is the OEM integrated furnace control (IFC) board for the Carrier PG8JAA036045ACJA gas furnace. The control board is the brain of your heating system — it sequences every stage of operation including draft inducer startup, hot surface ignition, gas valve activation, and blower motor management. When this board fails, symptoms typically include a no-heat condition, repeated ignition lockouts, erratic blower behavior, or a furnace that starts then immediately shuts down. Fault codes will often flash on the board's diagnostic LED to help pinpoint the failure before ordering.
