OEM Carrier Control Board for Model HB1AJX024000AAAA Unit

This OEM Carrier control board is the electronic brain of your HB1AJX024000AAAA condensing unit, managing compressor timing, fan operation, safety lockouts, and fault diagnostics. It interprets signals from the thermostat and pressure switches, then sequences the outdoor components to run safely and efficiently. Symptoms of a failing board include an unresponsive unit, repeated lockouts, erratic cycling, or diagnostic LED fault codes. Manufactured to exact Carrier specifications, this board ensures correct pin-out, relay logic, and timing for the HB1AJX024000AAAA, eliminating the guesswork and compatibility risk of universal replacements. Installation is moderate in difficulty—wiring must be transferred one terminal at a time and the board oriented correctly—so we recommend a licensed HVAC technician perform the swap. Always photograph existing connections and disconnect power before starting. A new control board restores reliable communication between your thermostat and outdoor unit and clears nuisance faults. In stock now—orders placed before 3PM CST ship the same business day.

Frequently Asked Questions

Does this Control Board fit my Carrier Model HB1AJX024000AAAA Unit?
Yes. This is the factory-specified OEM control board for the Carrier Model HB1AJX024000AAAA Unit. 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 HB1AJX024000AAAA Unit?
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?
