OEM Carrier Furnace Control Board HK42FZ061 for Model PG8JAA024045AGJA

The Carrier HK42FZ061 is the factory-original Integrated Furnace Control (IFC) board for the PG8JAA024045AGJA gas furnace. This board serves as the brain of the heating system — sequencing every stage of operation from inducer startup and pressure switch verification through hot surface ignition, gas valve activation, and blower motor control. When the IFC board fails, symptoms range from a complete no-heat lockout and unresponsive thermostat calls to erratic fault codes, ignition failures, or a blower that runs continuously without firing. Replacing with a genuine OEM board restores factory-programmed timing and diagnostic LED fault codes, eliminating the guesswork of aftermarket substitutes.
