OEM Carrier Economizer Control Board Kit HH63AW001 for Model CXCAECON12A00

This OEM economizer control board kit (part number HH63AW001) is the factory-specified replacement for the Carrier CXCAECON12A00 economizer assembly. The economizer control board manages outdoor air damper positioning, free-cooling logic, and ventilation sequencing to maximize energy efficiency and maintain indoor air quality. When this board fails, you may experience stuck dampers, erratic ventilation cycling, economizer fault codes, or a complete loss of free-cooling operation — all of which can trigger system lockouts and drive up energy costs.

• Specs: OEM Carrier economizer control board kit | Part No. HH63AW001 | Factory-matched control logic for damper actuator and enthalpy/dry-bulb sensor integration | 24V control circuit compatible | Designed for use with Carrier packaged and commercial HVAC economizer assemblies
• OEM vs Generic: This is a genuine Carrier OEM board, ensuring exact firmware logic, sensor calibration thresholds, and damper timing sequences. Aftermarket boards often lack proper enthalpy control programming, leading to overcooling, excess humidity infiltration, and premature compressor cycling.
• Install difficulty: 3/5 — Requires disconnecting low-voltage control wiring, damper actuator connectors, and sensor leads. Tools needed: Phillips and flathead screwdrivers, 1/4" nut driver, multimeter, and wiring diagram (refer to unit service manual). Photograph all wiring connections before removal. Confirm power is off at the disconnect before servicing.
• Warranty: 1-year OEM factory warranty against defects in materials and workmanship. Ships same business day from our climate-controlled warehouse.

Compatibility: This board is designed for the Carrier CXCAECON12A00 economizer unit. Verify your existing part number on the board label or unit data plate before ordering to confirm fitment. Compatible damper actuators, enthalpy sensors, and wiring harnesses should also be inspected during replacement. Have questions about fitment? Our HVAC parts specialists verify compatibility before you order — no guesswork required.
