OEM Carrier DCV Economizer Control Board Kit HH63AW001 for Model TFACCY48TM480094

This is a genuine OEM Carrier Economizer Control Board Kit (part# HH63AW001), the factory-specified replacement for the Carrier TFACCY48TM480094 packaged rooftop unit. The economizer control board is the intelligence center of the economizer module — it continuously monitors outdoor air conditions via CO₂ and enthalpy sensors and precisely controls the outdoor air damper to optimize free cooling and ventilation. When this board fails, you may experience loss of economizer function, stuck-open or stuck-closed dampers, ventilation fault codes, or the unit running full mechanical cooling even when outdoor conditions would allow free cooling. Addressing this failure promptly restores energy efficiency and maintains indoor air quality compliance.
