OEM Carrier Furnace Integrated Control Board HK42FZ061 for Model PG8JAA048135AGJA

This is the factory-original OEM Integrated Furnace Control (IFC) board for the Carrier PG8JAA048135AGJA gas furnace. The control board serves as the central command module of your furnace — it sequences ignition, monitors safety inputs from pressure switches, limit switches, and the flame sensor, and drives the inducer and blower motors through every heating cycle. When this board fails, the result is typically a complete no-heat condition, repeated ignition lockouts, erratic blower behavior, or a furnace that flashes diagnostic fault codes and refuses to run. Replacing it with the correct OEM part — not a generic substitute — is the surest path back to reliable, safe heat.

• OEM Part Number: HK42FZ061 | Manufactured by Carrier HVAC | Direct factory-matched replacement — no jumper or programming required out of the box.
• OEM vs Generic: OEM boards are built to exact Carrier circuit tolerances, ensuring proper timing sequences for ignition, blower delay, and fault detection. Third-party boards often ship with mismatched timing profiles that cause nuisance lockouts, premature component wear, or unsafe operation.

Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone or camera to photograph all wiring harness connections prior to removal.
