OEM Carrier Integrated Furnace Control Board HK42FZ016 for Model PG9MAA060140ACKA

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG9MAA060140ACKA packaged gas furnace, sold under primary part number HK42FZ016 and its current OEM successor kit number 325878-751. The IFC board is the brain of your furnace — it sequences the inducer motor, hot surface igniter, gas valve, and blower through every heat cycle. When it fails, symptoms range from a complete no-heat lockout and erratic blower behavior to an inducer that runs but ignition never initiates. A flashing diagnostic LED on the board itself will typically flash a fault code to help confirm the board as the culprit before replacement.

• 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-8.0 LRA at 120 VAC | Compatible with 24 VAC standard thermostat | OEM part numbers: HK42FZ016 / 325878-751
• OEM vs Generic: This is a genuine Carrier OEM board — not a third-party ICM282 aftermarket substitute. OEM boards carry factory-programmed timing sequences, precise fault logic, and full compatibility assurance for the PG9MAA060140ACKA. Aftermarket boards may ship with incorrect blower-off delays or missing fault codes, risking heat exchanger damage and voiding equipment warranties.
• Install difficulty: 3/5 — Disconnect power and gas before beginning. Tools needed: #2 Phillips screwdriver, 1/4" nut driver, needle-nose pliers, multimeter. Photograph all wire harness connections before removal. Note that this board controls ignition timing — improper wiring can cause unsafe ignition behavior. If unsure, consult a licensed HVAC technician.
• Warranty: 1-year OEM manufacturer warranty against defects. Orders placed by 3 PM local time ship same business day from our climate-controlled warehouse.
