OEM Carrier Control Board HK42FZ011 for Model GB1AAV060155ACJA

This OEM Carrier integrated furnace control board (HK42FZ011) is the brain of your GB1AAV060155ACJA, managing the ignition sequence, blower timing, safety lockouts, and thermostat communication. When your furnace won't respond to the thermostat, throws error-code flashes, or cycles erratically, a failed control board is a frequent culprit. This genuine board is an exact-fit replacement for the GB1AAV060155ACJA, pre-programmed with the correct timings and safety logic the universal aftermarket boards often get wrong. Installation is moderate and takes roughly 30-45 minutes: photograph the wiring, cut power, transfer each connector to the matching terminal on the new board, and remount. Always match wire-for-wire to avoid damage. Choosing the authentic Carrier component protects your blower motor, gas valve, and inducer from improper sequencing. Genuine OEM reliability you can trust through every heating season. In stock and ready — orders placed before 3PM CST ship same-day so you're not left in the cold.

Frequently Asked Questions

Does this Control Board fit my Carrier Model GB1AAV060155ACJA?
Yes. This is the factory-specified OEM control board for the Carrier Model GB1AAV060155ACJA. 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 GB1AAV060155ACJA?
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?
