OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TCHC1850HE401024

This is a genuine OEM Carrier Factory Authorized Part (HH63AW001), the factory-specified DCV Economizer Control Board Kit for the Carrier TCHC1850HE401024 commercial rooftop unit. The economizer control board serves as the command center for your unit's economizer system — continuously monitoring outdoor air conditions, CO₂ levels (in DCV-equipped systems), and enthalpy sensors to intelligently modulate the outdoor air damper. When this board fails, you may experience symptoms including a stuck-open or stuck-closed damper, erratic outdoor air modulation, CO₂ demand-controlled ventilation faults, loss of free-cooling capability, or fault codes related to the economizer circuit on the unit's control display.

  • OEM Part Number: HH63AW001 | Cross-reference: W7212A1017 | Genuine Carrier Factory Authorized Parts (FAP)
  • Specs: 120V | 60 Hz | Dimensions approx. 4″ × 4″ × 2″ | Weight: 1 lb | All inputs Class 2 rated | Designed for DCV (Demand Controlled Ventilation) economizer systems
  • OEM vs Generic: This OEM board is pre-programmed and factory-calibrated for Carrier RTU economizer logic. Aftermarket boards may lack DCV firmware, causing improper damper sequencing, false fault codes, and potential code-compliance issues with ASHRAE 62.1 ventilation standards.
  • Install Difficulty: 4/5 — Commercial rooftop board replacement requires shutting down the unit, safely isolating 120V supply, and carefully documenting all wiring connections before removal. Tools needed: screwdrivers (flathead and Phillips), needle-nose pliers, multimeter, and wiring labels. Recommend a qualified commercial HVAC technician for this repair.
  • Warranty: 1-year OEM factory warranty. Ships same business day from our warehouse.

Compatibility: Engineered as the direct OEM replacement for the Carrier TCHC1850HE401024 commercial packaged rooftop unit. Also cross-references Honeywell W7212A1017. Verify your existing board's part number against HH63AW001 before ordering. Have questions about fitment?

Frequently Asked Questions

Does this Control Board fit my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE401024?
Yes. This is the factory-specified OEM control board for the Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE401024. 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 — TCHC1850HE401024?
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?
