OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG8UAA060155ADJA

This is the factory OEM integrated furnace control (IFC) board for the Carrier PG8UAA060155ADJA gas furnace. Originally supplied as HK42FZ016 and currently fulfilled as the updated kit 325878-751, this microprocessor-based board orchestrates every critical furnace function — ignition sequencing, inducer and blower motor timing, gas valve control, and safety lockout logic. When it fails, the furnace may not start at all, experience repeated lockouts, run the blower continuously without heat, or fail to ignite after the inducer proves draft pressure. The onboard diagnostic LED flash codes are your first tool for pinpointing the exact fault before replacement.

• OEM Part Numbers: HK42FZ016 (original) | 325878-751 (current kit replacement, includes wiring adapter harnesses for legacy harness compatibility) | Cross-ref: CEPL130438-01, CEBD430438-09A, ICM282 series

• OEM vs Generic: The OEM 325878-751 kit ships with manufacturer-matched wiring adapter harnesses, ensuring plug-and-play fitment on both older and current harness configurations. Generic aftermarket boards (ICM282A/B series) can substitute in many cases but lack factory-programmed ignition timing curves and may void remaining equipment warranty.
• Install difficulty: 3/5 — Power down and lock out the furnace at the breaker before starting. Photograph all wiring connections before removal. The 325878-751 kit includes adapter harnesses if your existing wiring does not mate directly. Tools needed: flat-head and Phillips screwdrivers, 1/4" nut driver, needle-nose pliers, smartphone camera. Allow 30–60 minutes. Verify fault code label is applied to furnace door after installation.
