OEM Carrier Integrated Furnace Control Board HK42FZ016 for Model PG8UAA024065AAJA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG8UAA024065AAJA gas furnace, sold under primary part number HK42FZ016 and its direct supersession 325878-751 (Integrated Furnace Control Board Kit). The IFC board is the 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 include a furnace stuck in lockout, a blower that runs continuously, an igniter that energizes but never fires the gas valve, or a complete no-heat / no-response condition with no 24V output to downstream components.

• Specs: Input range 98–132 VAC at 60 Hz | Igniter output: 5A at 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat blower: 5A, 1/2 HP, 240 VAC | Inducer motor: 4A (FLA), 8.0A (LRA) at 120 VAC | Compatible with 24 VAC standard thermostat | Onboard diagnostic LED fault codes included
• OEM vs Generic: This is a genuine Carrier OEM board, factory-programmed with the exact sequencing delays and fault-code logic for the PG8UAA024065AAJA. Third-party ICM282-series boards can substitute in a pinch, but OEM ensures precise blower off-delay timing and full compatibility with Carrier's diagnostic protocol — critical for warranty and inspection compliance.
• Install difficulty: 3/5 — Shut off gas and 120V power at the disconnect before proceeding. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers, multimeter (to verify 24V control circuit before condemning board). Always photograph all wiring harness connections before removal. Electrostatic discharge precautions required — handle board by edges only.
• Warranty: 1-year OEM factory warranty against manufacturer defects. Orders placed before 3 PM ship same business day from our climate-controlled warehouse.
