OEM Carrier Economizer Control Board Kit HH63AW001 for Model TCHC1850HE403402

This is the factory OEM Economizer Control Board Kit (HH63AW001) for the Carrier TCHC1850HE403402 commercial rooftop unit. The economizer control board manages the outdoor air damper system, monitoring enthalpy or dry-bulb conditions to determine when free cooling from outside air is available. When this board fails, the unit may experience economizer fault codes, a damper stuck open or closed, erratic damper behavior, or a full system lockout — leading to increased energy costs and loss of proper ventilation or cooling control.

  • Specs: OEM Part Number HH63AW001 | Factory-matched economizer control board kit | Designed for Carrier commercial packaged rooftop units | Includes all required board components as a complete kit
  • OEM vs Generic: This is a genuine Carrier OEM board, calibrated to factory specifications for the TCHC1850HE403402. Aftermarket boards often lack proper enthalpy sensor calibration and damper actuator communication logic, risking repeat failures and code violations.

Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a phone or camera to photograph all wiring harness connections before removal. Confirm all DIP switch settings match the original board configuration.
  • Warranty: 1-year OEM factory warranty. In-stock units ship the same business day from our warehouse.

Frequently Asked Questions

Does this Control Board fit my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE403402?

How do I replace the control board on my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE403402?
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.
