OEM Carrier Integrated Furnace Control Board HK42FZ081 for Model PG96VTAA36060AAA

This is the OEM Carrier Integrated Furnace Control Board, originally sold as part number HK42FZ081 and now updated and fulfilled as its direct factory replacement, HK42FZ094. It is the factory-specified replacement for the Carrier PG96VTAA36060AAA 96% AFUE two-stage variable-speed gas furnace. The integrated furnace control (IFC) board is the brain of the furnace — it orchestrates every operating sequence including inducer startup, ignition trials, gas valve firing, blower motor staging, safety lockouts, and onboard fault-code diagnostics. When this board fails, symptoms range from a complete no-heat condition and repeated ignition lockouts, to erratic blower behavior, fault codes flashing on the LED, or the furnace failing to advance past the inducer prepurge stage.

• OEM Part Numbers: HK42FZ081 (original) | HK42FZ094 (current factory-issued replacement) | Cross-references: HK42FZ080, CEBD431102-05-RA, CEPL131102-21-R-I
• OEM vs Generic: This is a genuine Carrier factory-authorized board — not an aftermarket approximation. OEM boards are pre-programmed with Carrier-specific ignition timing, blower delay profiles, and safety lockout sequences. Generic boards often mis-match timing parameters, causing nuisance lockouts, voided equipment warranties, and potential safety hazards.
• Install Difficulty: 4/5 — Requires shutting off gas and 120V power at the disconnect before any work begins. Document all wire connections with photos before removal. Tools needed: ¼" and 5/16" nut drivers, needle-nose pliers, multimeter, and a phone camera for wiring reference. Incorrect wiring can damage the new board — professional installation is strongly recommended for this component.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our climate-controlled warehouse.
