OEM Carrier Furnace Control Board HK42FZ034 for Model GB1AAV060155AEJA

Bring your GB1AAV060155AEJA furnace back to full operation with this genuine OEM Carrier integrated control board (HK42FZ034). The board orchestrates the entire heating sequence—ignition timing, blower and inducer control, safety lockouts, and the diagnostic LED that flashes fault codes. A failed board can cause a completely unresponsive furnace, random blower cycling, or persistent error flashes that defy other repairs. This exact-fit replacement is programmed to Carrier's original specifications for the GB1AAV060155AEJA, ensuring correct relay logic, terminal arrangement, and connector fit. Installation is a moderate job best left to an HVAC professional—roughly 30 to 45 minutes: photograph the existing wiring, move connectors one at a time, and match the dip-switch and jumper settings to the original board. Always disconnect power at the furnace before starting. Installing the genuine OEM board prevents the intermittent faults and miswiring risks that come with generic boards. In stock and ships same-day when you order before 3PM CST. Restore reliable, code-correct heating quickly with the board Carrier built for your system.

Frequently Asked Questions

Does this Control Board fit my Carrier Model GB1AAV060155AEJA?
Yes. This is the factory-specified OEM control board for the Carrier Model GB1AAV060155AEJA. 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 GB1AAV060155AEJA?
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?
