OEM Carrier Furnace Control Board HK42FZ013 for Model PG8JAA036070ADJA

This OEM integrated furnace control (IFC) board is the factory-specified replacement for the Carrier PG8JAA036070ADJA gas furnace. The control board is the brain of your furnace — it sequences every operating stage including inducer start-up, ignition, gas valve activation, blower motor timing, and safety shutdown logic. When this board fails, symptoms typically include a complete no-heat lockout, fault codes flashing on the diagnostic LED, the furnace starting then immediately shutting down, or erratic blower behavior that won't respond to thermostat commands.
