OEM Carrier Furnace Control Board HK42FZ061 for Model PG8JAA036045AGJA

The Carrier HK42FZ061 is the factory-specified Integrated Furnace Control (IFC) board for the PG8JAA036045AGJA packaged gas unit. This board is the central brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower, while continuously monitoring input from the pressure switch, flame sensor, and limit switches. When the control board fails, common symptoms include a furnace stuck in lockout mode, no ignition attempts, erratic short-cycling, or a completely unresponsive system with no LED fault codes.
