OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TCHC1850HE403349

This is a genuine OEM Carrier Economizer Control Board Kit (part #HH63AW001), factory-specified for the Carrier TCHC1850HE403349 commercial packaged rooftop unit. The economizer control board is the intelligence center of the unit's demand-controlled ventilation (DCV) system — it continuously monitors outdoor air conditions and modulates the economizer damper to blend the optimal ratio of outdoor and recirculated air. When this board fails, common symptoms include stuck-open or stuck-closed dampers, loss of demand-controlled ventilation, increased energy consumption, fault codes on the thermostat or BMS, and degraded indoor air quality (IAQ) in the conditioned space.

  • OEM vs Generic: This is a genuine Carrier Factory Authorized Part, manufactured to exact OEM tolerances. Generic or aftermarket control boards often lack proper firmware calibration for Carrier DCV sequences, risking damper hunting, incorrect free-cooling lockout temperatures, and potential ASHRAE 62.1 compliance failures.
  • Install difficulty: 3/5 — Disconnect and lock out power before beginning. Document all wiring connections with photographs before removing the old board. Tools needed: flathead and Phillips screwdrivers, needle-nose pliers, multimeter (to verify 120V supply and 24V control circuit). Commercial rooftop application — follow all applicable electrical codes. Professional installation recommended.
  • Warranty: 1-year OEM manufacturer warranty. In-stock and ships same business day from our warehouse.

Compatibility: Designed for the Carrier TCHC1850HE403349 commercial rooftop unit. Cross-references OEM part numbers HH63AW001 and W7212A1017.

Frequently Asked Questions

Does this Control Board fit my Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE403349?
Yes. This is the factory-specified OEM control board for the Carrier OEM Carrier Economizer Control Board Kit HH63AW001 — TCHC1850HE403349. 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 — TCHC1850HE403349?
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.
