OEM Carrier Control Board HK61EA005 for HA1BJX018000AEAA

This OEM Carrier defrost control board (HK61EA005) is the brain of your outdoor unit, orchestrating compressor timing, fan operation, and safety lockouts to keep your system running safely and efficiently. Designed specifically for the Carrier HA1BJX018000AEAA 1.5-ton condenser, it delivers the precise relay logic and timing delays the unit needs to start and run without short-cycling or compressor strain. A faulty board often shows up as a unit that won't start, ignores the thermostat, or cycles erratically—frequently after a power surge or storm. Replacement is a moderate repair for a qualified technician: disconnect power, photograph every low- and line-voltage connection, transfer the plugs and leads to the matching terminals on the new board, and remount. Plan on 30 to 45 minutes. The genuine Carrier board guarantees correct firmware, relay ratings, and terminal layout, ensuring proper operation and protecting your warranty. We keep this board in stock and ship same-day on orders placed before 3PM CST. Order today from National HVAC Parts.

Frequently Asked Questions

Does this Control Board fit my Carrier HA1BJX018000AEAA?
Yes. This is the factory-specified OEM control board for the Carrier HA1BJX018000AEAA. 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 HA1BJX018000AEAA?
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?
