OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG9MAA060120ADKA

This OEM integrated furnace control (IFC) board is the factory-specified replacement for the Carrier PG9MAA060120ADKA gas furnace. The IFC board is the brain of your heating system — it sequences the inducer motor, hot surface igniter, gas valve, and blower motor on every call for heat. When the board fails, symptoms range from a complete no-heat lockout and non-responsive thermostat calls, to erratic blower behavior, repeated ignition failures, or diagnostic LED fault codes that won't clear. Primary OEM part number is HK42FZ016, superseded by the current factory kit 325878-751 (Integrated Furnace Control Board Kit), which includes adapter wiring harnesses for a direct plug-in upgrade.

  • Specs: 24 VAC control circuit | Input range 98–132 VAC @ 60 Hz | Ignitor output: 5A @ 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat output: 5A, 1/2 HP, 240 VAC | Inducer motor: 4A, FLA-8.0 LRA @ 120 VAC | Microprocessor-based with diagnostic LED fault codes
  • OEM vs Generic: This is a genuine Carrier OEM board, factory-programmed with the exact sequencing logic, timing delays, and safety lockout parameters for the PG9MAA060120ADKA. Generic aftermarket boards may lack model-specific timing profiles, increasing the risk of nuisance lockouts or premature heat exchanger stress.
  • Install difficulty: 3/5 — Shut off power and gas before beginning. Tools needed: 1/4" nut driver, flathead screwdriver, needle-nose pliers, multimeter. Photograph all wiring harness connections before disconnecting. The 325878-751 kit includes adapter harnesses for older-style connector configurations. Always verify 24V transformer output before condemning the board.
  • Warranty: 1-year OEM factory warranty against manufacturing defects. Ships same business day from our warehouse in original factory packaging.

Compatibility: Factory-matched for Carrier model PG9MAA060120ADKA single-stage gas furnace. OEM part HK42FZ016 is superseded by kit 325878-751; both part numbers are fulfilled by the current 325878-751 board kit. Verify your existing board's part number on the label before ordering.

Frequently Asked Questions

Does this Control Board fit my Carrier PG9MAA060120ADKA?
Yes. This is the factory-specified OEM control board for the Carrier PG9MAA060120ADKA. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.
How do I replace the control board on my Carrier PG9MAA060120ADKA?
Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.
My HVAC system is completely dead. What could be wrong?
Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.
Is this control board compatible with Bryant or Payne too?
Many Carrier parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.
Should I use OEM or aftermarket for my Carrier control board?
OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
How fast does National HVAC Parts ship?
