OEM Carrier Integrated Furnace Control Board HK42FZ018 for Model PG9YAA060100ACSS

This is the factory OEM Integrated Furnace Control (IFC) board for the Carrier PG9YAA060100ACSS gas furnace. The control board is the brain of your heating system — it sequences ignition, monitors safety switches and pressure sensors, drives inducer and blower timing, and triggers lockout codes when a fault is detected. Common failure symptoms include the furnace not heating at all, repeated ignition lockouts, erratic or short-cycling operation, blower running continuously, or error codes flashing on the board itself. If your furnace is stuck in a fault loop or won't advance past a specific stage, the IFC board is a primary suspect after ruling out individual components.

  • OEM Part Number: HK42FZ018 | Cross-references: CEPL130590-01, CEBD430590-10A | Factory-matched firmware and relay ratings for the PG9YAA060100ACSS
  • OEM vs Generic: This is a genuine Carrier OEM board — not an aftermarket clone. OEM boards carry factory-calibrated timing sequences and relay logic. Aftermarket boards can introduce ignition timing drift or false safety trips that void equipment warranties.
  • Install Difficulty: 3/5 — Board replacement requires shutting off gas and 120V power, photographing and labeling all wire harness connections, and verifying jumper settings match the removed board. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, phone camera for wiring photos. Basic HVAC service knowledge recommended; consult a licensed technician if unsure.
  • Warranty: 1-year OEM factory warranty against defects. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier PG9YAA060100ACSS packaged gas furnace. Also fits select Carrier, Bryant, and Payne models using the HK42FZ018 board — always verify the part number on your existing board's label before ordering. Questions about fitment?

How do I replace the control board on my Carrier OEM Carrier Integrated Furnace Control Board HK42FZ018 — PG9YAA060100A?
Difficulty: Advanced (1–2 hrs)

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.
