OEM Carrier DCV Economizer Control Board Kit HH63AW001 for TCHC1850HE401025

This is a genuine OEM Carrier Factory Authorized Part (HH63AW001), the direct factory replacement for the DCV Economizer Control Board Kit used in the Carrier TCHC1850HE401025 commercial rooftop unit. The economizer control board is the intelligence center of your unit's free-cooling system — it continuously monitors outdoor air conditions, CO₂ levels (in DCV-equipped systems), and enthalpy to determine when and how much outside air to introduce. When this board fails, symptoms include economizer damper stuck open or closed, fault codes indicating economizer communication errors, poor indoor air quality, increased energy consumption, and failed building energy code compliance.

Photograph all wiring harness connections before disconnecting. Verify all sensor inputs are reseated and DCV sensor (if applicable) is re-calibrated after install.

Frequently Asked Questions

Does this Control Board fit my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE401025?
Yes. This is the factory-specified OEM control board for the Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE401025. 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 OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE401025?
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?
