OEM Carrier Economizer Control Board Kit HH63AW001 for Model TFACCY48TM482637

This is a genuine OEM Carrier Economizer Control Board Kit (part# HH63AW001), the factory-specified replacement for the Carrier TFACCY48TM482637 packaged rooftop unit. The economizer control board is the command center for your unit's demand-controlled ventilation (DCV) system — it continuously monitors indoor CO₂ levels and outdoor air conditions, modulating the economizer damper to optimize fresh air intake and reduce mechanical cooling load. When this board fails, common symptoms include stuck-open or stuck-closed dampers, DCV fault codes, erratic outdoor air percentages, or a complete economizer lockout that forces the unit into full mechanical cooling at all times.

  • Specs: Carrier OEM Part# HH63AW001 | DCV Economizer Control Board Kit | 120V / 60Hz | Cross-reference: W7212A1017 | Dimensions approx. 4" × 4" × 2" | Weight: 1 lb
  • OEM vs Generic: This is a genuine Factory Authorized Parts board built to exact Carrier tolerances. OEM boards ensure full compatibility with the unit's communication bus, sensor inputs, and damper actuator outputs — critical for accurate DCV operation and energy code compliance.
  • Install Difficulty: 3/5 — Board replacement requires disconnecting low-voltage wiring harnesses and verifying DCV sensor connections. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter, and a laptop or handheld tool to re-configure DCV set points post-installation. Always de-energize the unit at the disconnect before servicing.
  • Warranty: 1-year OEM manufacturer warranty. In stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier TFACCY48TM482637 commercial packaged rooftop unit. Also cross-references Honeywell W7212A1017 for compatible Bryant and Payne rooftop platforms. Verify your existing board's part number on the unit data plate or board label before ordering. Our team is available to confirm fitment — don't guess on a control board.

Frequently Asked Questions

Does this Control Board fit my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TFACCY48TM482637?
Yes. This is the factory-specified OEM control board for the Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TFACCY48TM482637. 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 — TFACCY48TM482637?
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?
