OEM Carrier Economizer Control Board Kit HH63AW001 for Model TCHC1850HE403358

This is the factory OEM replacement Economizer Control Board Kit (Part # HH63AW001) for the Carrier TCHC1850HE403358 commercial rooftop unit. The economizer control board manages the outdoor air damper actuator, monitors enthalpy or dry-bulb sensors, and coordinates free-cooling cycles to maximize energy efficiency. When this board fails, common symptoms include economizer dampers stuck open or closed, fault codes on the thermostat or BAS interface, erratic damper hunting, or a complete loss of economizer function — causing the unit to run mechanical cooling even when outdoor conditions would allow free cooling.

  • Specs: OEM Part # HH63AW001 | Economizer Control Board Kit | Factory-matched for Carrier TCHC1850HE403358 commercial rooftop | Includes all necessary mounting hardware per kit specification
  • OEM vs Generic: This is a genuine Carrier OEM board — firmware, sensor calibration thresholds, and damper actuator signal profiles are factory-programmed to exact specifications. Aftermarket boards may lack proper enthalpy calibration, resulting in incorrect free-cooling lockout points and failed energy code compliance.
  • Install Difficulty: 3/5 — Requires shutdown of the rooftop unit and lockout/tagout procedure. Tools needed: flathead and Phillips screwdrivers, 1/4" and 5/16" nut drivers, multimeter, and wiring diagram (located inside unit panel door). Photograph all wiring harness connections before disconnecting. Re-commissioning the economizer per Carrier startup procedure is recommended after installation.
  • Warranty: 1-year OEM factory warranty against defects in materials and workmanship. In-stock and ships same business day from our climate-controlled warehouse.

Compatibility: Engineered specifically for the Carrier TCHC1850HE403358 commercial packaged rooftop unit. Always verify your existing board's part number against HH63AW001 before ordering, and confirm economizer type (enthalpy vs. dry-bulb) matches your unit's original configuration. Our HVAC parts specialists are available to confirm fitment — contact us before you order if you have any questions. Order today and ships same business day.

Frequently Asked Questions

Does this Control Board fit my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE403358?
Yes. This is the factory-specified OEM control board for the Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE403358. 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 — TCHC1850HE403358?
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?
