OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TCHC1850HE403395

This is a genuine OEM Carrier Economizer Control Board Kit (part# HH63AW001), the factory-authorized replacement for the Carrier TCHC1850HE403395 commercial rooftop unit. The DCV (Demand-Controlled Ventilation) economizer control board serves as the intelligence center of your unit's economizer system — it continuously monitors outdoor air conditions, CO₂ levels (when a DCV sensor is present), and enthalpy to determine when free-cooling with outside air is both possible and energy-efficient. When this board fails, symptoms include the economizer damper becoming stuck open or closed, fault codes related to the economizer circuit, loss of free-cooling operation, or the unit failing to meet ventilation code requirements entirely.

  • Part Number & Specs: OEM Carrier HH63AW001 | DCV Economizer Control Board Kit | Input Voltage: 120V / 60Hz | Cross-reference: W7212A1017 | Dimensions: approx. 4" × 4" × 2" | Weight: ~1 lb | All inputs Class 2
  • OEM vs Generic: This factory-authorized OEM board is pre-programmed to Carrier's exact DCV logic and enthalpy algorithms. Aftermarket substitutes may lack proper DCV calibration, leading to ventilation code violations and increased energy consumption — particularly critical in commercial applications subject to ASHRAE 62.1 compliance.
  • Install Difficulty: 3/5 — Commercial rooftop economizer board replacement requires safe rooftop access and lockout/tagout procedures. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a laptop with Carrier service software if DCV sensor recalibration is required. Always photograph all wiring harness connections before removal. Recommended for qualified HVAC technicians.
  • Warranty & Shipping: Backed by a 1-year OEM factory warranty. Ships same business day from our warehouse — get your commercial system back online fast.

Compatibility: Designed as a direct OEM replacement for the Carrier TCHC1850HE403395 commercial rooftop unit. Also cross-references Honeywell W7212A1017. Verify your existing board's part number against HH63AW001 before ordering. Have a question about fitment?

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.
