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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e 120V | 60Hz | DCV (Demand Controlled Ventilation) capable | Dimensions: approx. 4\" × 4\" × 2\" | Weight: ~1 lb | Cross-reference: W7212A1017\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier Factory Authorized Part, engineered to exact DCV logic and sensor-input tolerances for the TFACCY48TM480094.
