Description
The York S1-324-39721-011 is a factory-programmed Electronically Commutated Motor (ECM) designed as a direct OEM replacement for compatible York heating and cooling systems. Operating at 120 volts and rated at 1/2 horsepower, this motor delivers the precise, variable-speed airflow performance that ECM technology is known for — improving system efficiency, reducing energy consumption, and providing quieter operation compared to traditional PSC motors.
As a pre-programmed unit, the S1-324-39721-011 is ready for drop-in installation without the need for external programming modules, making it an ideal solution for service technicians looking to restore original system performance quickly and reliably.
Key Features
- OEM York replacement ECM blower motor
- Operating voltage: 120V
- Motor horsepower: 1/2 HP
- Factory pre-programmed for direct drop-in replacement
- Electronically Commutated Motor (ECM) technology for variable-speed operation

- Engineered for compatibility with York HVAC systems
Why ECM Technology?
ECM motors use a brushless DC design controlled by an internal microprocessor, allowing the motor to adjust its speed in response to system demand. This results in more consistent airflow, better humidity control, and significantly lower electricity usage — especially during part-load operation. Replacing a failed blower motor with the correct OEM-programmed ECM ensures your York system continues to operate at its designed efficiency rating.
Application
- Designed for use in York residential and light commercial HVAC equipment
- Suitable for gas furnaces, air handlers, and heat pump systems requiring a 120V, 1/2 HP ECM blower motor
- Always verify compatibility with your specific York model number before installation
