OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG8DAA036095ADJA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG8DAA036095ADJA gas furnace, sold under primary OEM part number HK42FZ016 and its current successor kit 325878-751. The IFC board is the brain of your furnace — it sequences every heating cycle from inducer startup through ignition, gas valve control, blower operation, and safe shutdown. When it fails, symptoms include a complete no-heat lockout, furnace starting then immediately shutting down, erratic blower behavior, or a fault LED flashing a diagnostic code with no recovery.

• Specs: Input Voltage: 98–132 VAC at 60 Hz | Ignitor Output: 5A at 120 VAC | Cool Blower: 30A, 2 HP, 240 VAC | Heat Blower: 5A, 1/2 HP, 240 VAC | Inducer Motor: 4A, FLA-8.0 LRA at 120 VAC | Compatible with 24 VAC standard thermostats | Diagnostic LED fault codes included
• OEM vs Generic: This is a genuine Carrier OEM board — not a third-party ICM282 clone. OEM firmware is factory-calibrated to the exact ignition timing, blower delay profiles, and lockout thresholds of the PG8DAA036095ADJA. Aftermarket boards often use generalized firmware that can cause nuisance lockouts or premature component wear.
• Install Difficulty: 3/5 — Shut off gas and 120V power before starting. Photograph all wiring harness connections before disconnecting. The 325878-751 kit includes adapter plug harnesses for compatibility with older board generations. Tools needed: 1/4" nut driver, needle-nose pliers, smartphone camera. Always verify fault LED label is affixed to furnace door after install. Estimated time: 30–60 minutes.
• Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse in OEM-protective packaging.
