OEM Carrier Integrated Furnace Control Board HK42FZ016 / 325878-751 for Model PG9MAA060120AAKA

This is the factory OEM integrated furnace control (IFC) board for the Carrier PG9MAA060120AAKA 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 through every heating and cooling cycle. When it fails, symptoms range from a complete no-heat lockout and continuous LED fault codes to erratic blower operation, short-cycling, or a furnace that starts then shuts down mid-cycle. Note: OEM part number HK42FZ016 has been superseded by the updated kit 325878-751, which includes wiring adapter harnesses for seamless plug-and-play installation on older harness configurations.

  • Specs: Input: 98–132 VAC @ 60 Hz | Igniter output: 5A @ 120 VAC | Cool blower: 30A, 2 HP, 240 VAC | Heat: 5A, 1/2 HP, 240 VAC | Inducer: 4A (FLA), 8.0A (LRA) @ 120 VAC | 24 VAC standard thermostat compatible
  • OEM vs Generic: This OEM board ships from Carrier's factory-authorized supply chain with verified firmware and tolerance specs. Aftermarket ICM282-series boards may lack factory diagnostic logic, increasing the risk of nuisance lockouts and shortened component life.
  • Install difficulty: 3/5 — Power off and tag out the furnace before beginning. Tools needed: 1/4" and 5/16" nut drivers, needle-nose pliers, phone/camera to photograph all wiring connections before removal. The 325878-751 kit includes adapter harnesses if your existing wiring does not mate directly to the new board's connectors.
  • Warranty: 1-year OEM manufacturer warranty against defects. Ships same business day from our warehouse.

Compatibility: Direct OEM replacement for Carrier PG9MAA060120AAKA gas furnace. Also cross-references Carrier/Bryant/Payne models using HK42FZ004, HK42FZ007, HK42FZ008, HK42FZ009, HK42FZ011, HK42FZ013, and HK42FZ034 boards. Always verify your existing part number on the board label before ordering. Questions about fitment? Our HVAC-certified team confirms compatibility before you buy.

How do I replace the control board on my Carrier OEM Carrier IFC Control Board HK42FZ016 / 325878-751 — PG9MAA060120AAK?
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.
