York S1-324-36074-439 Blower Motor

The York S1-324-36074-439 Blower Motor is a high-performance 3/4HP ECM blower motor engineered for precise airflow management in residential and commercial York HVAC systems. Designed to replace aging or failed units in equipment like the York BBUP-F036A, this electronically commutated motor provides the constant torque and variable speed capabilities necessary to maintain critical static pressure balance. As a programmed ECM motor, it integrates seamlessly with the system control board, ensuring that the airflow ramps up and down efficiently to reduce mechanical stress and electrical consumption. For technicians, this York OEM replacement motor simplifies the 10-pin or 16-pin interface connections (depending on the specific module configuration) and maintains the specific CW rotation requirements for York blower assemblies. Built for 208-230V applications, this direct drive blower motor is the standard for restoring factory-spec performance and quiet operation to high-efficiency air handlers and furnaces.

• High-Efficiency ECM Technology: Provides 3/4 HP of power with significantly lower amperage draw compared to traditional PSC motors.
• Variable Speed Control: Maintains proper CFM delivery across varying static pressures to prevent coil freezing and ensure comfort.
• OEM Compatibility: Exact replacement for York S1-324-36074-439 and cross-referenced 208T82 models, ensuring mounting and wiring alignment.
• Quiet Operation: Controlled ramping cycles reduce the audible "thump" of the blower starting and minimize vibration through the ductwork.
• Durable Construction: Engineered to handle the high-duty cycles of modern climate control systems without overheating.

Does this motor include the pre-programmed control module?
Yes, this is a fully programmed ECM blower motor, meaning the logic module is integrated and flashed with the specific performance curves required for compatible York hardware.

What are the symptoms of a failing York ECM motor?
Common indicators include the motor failing to start despite receiving 24VAC signals, hunting/surging speeds, or high-pitched bearing noise. Technicians should also check for a failed module if the motor "shudders" but won't pin.

Is this a direct replacement for 1/2 HP motors?
No, you should never undersize or oversize an ECM motor. This 3/4 HP unit is designed specifically for systems rated for this torque profile to avoid damaging the control board or causing airflow imbalances.
