OEM Carrier Control Board HK42FZ034 for Model GB1AAV060155AGJA Furnace

This OEM Carrier integrated furnace control board (HK42FZ034) is the central controller for your GB1AAV060155AGJA gas furnace, sequencing ignition, inducer, gas valve, and blower while monitoring every safety switch. It interprets the flame sensor, pressure switch, and limit inputs, then fires the igniter and stages the blower with the correct timing. When this board fails you'll see a completely dead furnace, flashing diagnostic LEDs, or a blower that runs nonstop. This genuine Carrier board ships with the correct firmware and matches the GB1AAV060155AGJA harness so every connector and terminal lines up exactly. Installation is moderate — power down, photograph the existing wiring, move the labeled plugs over one at a time, and remount on the factory standoffs in about 30 minutes. The OEM board avoids the timing and miswiring faults that plague generic substitutes. Replacing it restores full, safe, code-compliant operation and clears persistent lockouts. Order before 3PM CST for same-day shipping from our in-stock inventory and minimize downtime. Genuine OEM quality gives you dependable, safe heating control you can rely on.

Frequently Asked Questions

Does this Control Board fit my Carrier Model GB1AAV060155AGJA Furnace?
Yes. This is the factory-specified OEM control board for the Carrier Model GB1AAV060155AGJA Furnace. 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 GB1AAV060155AGJA Furnace?
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?
