OEM Carrier Integrated Furnace Control Board HK42FZ016 for Model PG9MAA024060ADKA

This is the factory OEM integrated furnace control board (IFC) for the Carrier PG9MAA024060ADKA gas furnace, supplied under part numbers HK42FZ016 and kit number 325878-751. The IFC board is the brain of your furnace — it sequences the inducer motor, igniter, gas valve, and blower in a precise order on every call for heat. When it fails, symptoms range from a complete no-heat lockout and error code flashing to erratic short-cycling, a blower that runs continuously, or a furnace that stages through ignition but shuts down unexpectedly. Before replacing the board, verify your flame sensor, igniter, and pressure switch are functioning correctly, as a faulty downstream component can mimic a failed board.

  • OEM Part Numbers: HK42FZ016 (board only) | 325878-751 (Integrated Furnace Control Board Kit — includes wiring adapter harnesses for legacy-to-modern board upgrades)
  • OEM vs Generic: This is a genuine Carrier factory-authorized board, manufactured to exact firmware and relay specifications. Aftermarket boards may use lower-rated triacs and relays that reduce service life or cause nuisance lockouts not present with the OEM unit.
  • Install Difficulty: 3/5 — Requires shutting off 120V power and 24V control circuit before starting. Photograph all wiring connections before removal. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone camera for documentation. The 325878-751 kit includes adapter harnesses if upgrading from an older-style board.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before cutoff.

Compatibility: Designed and factory-matched for Carrier model PG9MAA024060ADKA. Part 325878-751 also supersedes earlier HK42FZ-series boards (HK42FZ004, HK42FZ007, HK42FZ008, HK42FZ009, HK42FZ011) — confirm your existing board's part number before ordering.

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?

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.
