OEM Carrier Integrated Furnace Control Board HK42FZ081 for Model PG96VTAA60080CAA

The Carrier HK42FZ081 Integrated Furnace Control (IFC) Board is the factory-specified OEM replacement for the PG96VTAA60080CAA 96% AFUE variable-speed gas furnace. Acting as the brain of your heating system, this board orchestrates every critical operation — ignition sequencing, inducer and blower motor staging, gas valve control, pressure switch monitoring, and LED fault-code diagnostics. When this board fails, symptoms typically include a complete no-heat lockout, erratic ignition attempts, blower running continuously or not at all, or flashing fault codes that won't clear after a power reset.

• Part Number & Specs: OEM Part # HK42FZ081 | 24V control circuit | Microprocessor-based ignition and blower timing control | Factory-programmed for Carrier PG96VTAA60080CAA furnace logic
• OEM vs Generic: OEM boards are factory-programmed with the exact timing sequences, safety lockout thresholds, and fault-code protocols required by your specific furnace model. Third-party aftermarket boards often use generalized firmware that can cause nuisance lockouts, incorrect blower delays, or incompatibility with variable-speed motors — accelerating wear and voiding remaining equipment warranty.
• Install Difficulty: 4/5 — Board replacement requires disabling power at the breaker and shutting off the gas supply. Photograph all wiring harness connections and connector positions before removal. Tools needed: Phillips and flat-head screwdrivers, needle-nose pliers, multimeter for 24V control circuit verification. Note: the model identification plug from the existing board must be transferred to the new board. Recommend professional installation if unfamiliar with furnace control wiring.
• Warranty & Shipping: 1-year OEM factory warranty against defects. In stock — ships same business day from our warehouse. Free shipping on this order.

Compatibility: This board is the direct OEM replacement for Carrier model PG96VTAA60080CAA. Always verify your existing board's part number label before ordering, as Carrier IFC boards are model-specific and not universally interchangeable across the PG96V series.
