OEM Carrier Furnace Control Board HK42FZ034 for Model GB1AAV060155ADJA

Get your GB1AAV060155ADJA furnace running reliably again with this genuine OEM Carrier integrated control board (HK42FZ034). This board is the control center of the furnace, governing the ignition sequence, blower and inducer timing, safety lockouts, and the diagnostic LED fault codes that guide troubleshooting. When it fails you may face a dead furnace, erratic blower behavior, or stubborn flashing codes that persist after other parts are replaced. This exact-fit replacement is programmed to Carrier's original specifications for the GB1AAV060155ADJA, ensuring proper relay logic, terminal layout, and connector compatibility. Installation is moderate and best performed by an HVAC technician—about 30 to 45 minutes: photograph all wiring first, transfer connectors individually, and verify dip-switch and jumper settings match the original. Always shut off power at the disconnect before servicing. The genuine OEM board avoids the misfires and compatibility headaches of universal alternatives. In stock and ships same-day when you order before 3PM CST. Restore safe, accurate furnace operation fast with the board Carrier designed for your system.

Frequently Asked Questions

Does this Control Board fit my Carrier Model GB1AAV060155ADJA?
Yes. This is the factory-specified OEM control board for the Carrier Model GB1AAV060155ADJA. 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 Model GB1AAV060155ADJA?
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?
