OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TCHC1850HE401483

This is a genuine OEM Carrier Factory Authorized Part — the DCV Economizer Control Board Kit (part# HH63AW001) — engineered as the direct replacement for commercial rooftop units including the Carrier TCHC1850HE401483. The economizer control board acts as the brain of the economizer system, continuously monitoring outdoor air conditions via CO₂ and enthalpy sensors and modulating the outdoor air damper to maximize free cooling and maintain indoor air quality (IAQ). When this board fails, you may experience symptoms such as damper stuck open or closed, erratic economizer cycling, fault codes on the unit controller, excessive energy consumption, or complete loss of demand-controlled ventilation (DCV) function.

  • Specs: 120V | 60Hz | DCV Demand-Controlled Ventilation logic | Dimensions approx. 4.7" × 3.2" | Weight: 1 lb | Cross-reference: W7212A1017
  • OEM vs Generic: This factory-authorized OEM board carries pre-loaded Carrier firmware and calibrated sensor thresholds. Aftermarket boards often require manual recalibration and may not support full DCV logic, risking code compliance failures on commercial installations.
  • Install difficulty: 3/5 — Requires disconnecting 24V control wiring, CO₂/enthalpy sensor leads, and damper actuator connections. Tools needed: insulated screwdrivers, needle-nose pliers, multimeter, wiring diagram. Always de-energize unit at disconnect before servicing. Recommend a qualified commercial HVAC technician for installation.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse when ordered before 3PM local time.

Compatibility: Engineered for the Carrier TCHC1850HE401483 commercial rooftop unit. Also cross-references Honeywell W7212A1017. Verify your unit's control board part number on the component label inside the economizer compartment before ordering. Not sure it fits?

Frequently Asked Questions

Does this Control Board fit my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE401483?
Yes. This is the factory-specified OEM control board for the Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE401483. 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 — TCHC1850HE401483?
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.
