OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG8DAA024050ABJA

This is the factory OEM replacement integrated furnace control (IFC) board for the Carrier PG8DAA024050ABJA gas furnace, superseding original part number HK42FZ016 under updated kit number 325878-751. The IFC board is the central brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor on every call for heat. When it fails, symptoms range from a complete no-heat lockout and unresponsive thermostat to erratic blower behavior, repeated ignition failures, or fault LED flash codes that won't clear. Replacing this board with a genuine OEM unit restores factory-programmed timing and safety logic exactly as Carrier designed it.

• OEM Part Numbers: HK42FZ016 (original) | 325878-751 (current superseding kit with adapter harnesses) | Cross-references: CEPL130438-01, CEBD430438-09A, ICM282 series
• Electrical Specs: Input voltage range 98–132 VAC @ 60 Hz | Igniter output: 5A @ 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat blower: 5A, 1/2 HP, 240 VAC | Inducer motor: 4A FLA / 8.0A LRA @ 120 VAC | Gas valve: 24 VAC | Compatible with standard 24 VAC thermostat | Onboard diagnostic LED flash codes
• OEM vs. Generic: The OEM 325878-751 kit ships with factory wiring adapter harnesses, ensuring a direct plug-in replacement on both older HK42FZ016-style boards and current production units. Generic aftermarket boards (ICM282A/B equivalents) omit these harnesses and may require field wiring modifications — increasing labor time and risk of miswiring. OEM firmware also preserves factory-calibrated ignition retry timing and 100% gas shutoff on ignition failure.
• Install Difficulty: 3/5 — Power down and lock out the furnace before beginning. Photograph all wiring connections before disconnecting. The 325878-751 kit includes adapter harnesses for legacy connectors. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, multimeter (to confirm 24V control circuit). Verify fault LED codes before and after replacement. Recommended for experienced DIYers or licensed HVAC technicians.
• Warranty: Genuine Carrier OEM — 1-year manufacturer's warranty against defects. Ships same business day from our stocked warehouse.
