York S1-324-36073-446 Blower Motor

The York S1-324-36073-446 is an OEM 1/2HP ECM blower motor designed for high-efficiency air delivery in York, Luxaire, and Coleman residential furnaces and air handlers. As a genuine HVAC replacement motor, it operates at a rated speed of 1075 RPM, utilizing electronically commutated motor technology to provide variable speed control and superior energy savings over standard PSC motors. This direct-drive motor is pre-programmed to interface seamlessly with your specific air handler control board, ensuring precise CFM (Cubic Feet per Minute) delivery across various static pressure conditions. Technicians should verify the 16-pin and 5-pin connectors for voltage before installation; remember that for 120V applications, a jumper is typically required between pins 1 and 2, while 240V configurations remain open. This York blower motor is a critical component for restoring system static balance and maintaining quiet, reliable ventilation performance.

Key Benefits:

• Optimized Efficiency: High-efficiency ECM design reduces electrical consumption compared to traditional induction motors.
• OEM Compatibility: Precision-engineered for exact fitment in York HVAC equipment, eliminating the need for universal mounting adjustments.
• Constant Airflow: Programmed to adjust torque and speed to maintain consistent airflow even as duct static pressure increases.
• Reduced Noise: Soft-start technology minimizes "thumping" sounds and provides quieter ramp-up and ramp-down cycles.
• Durability: Features ball-bearing construction and a totally enclosed design suitable for demanding indoor air movement applications.

Common Questions:

How do I troubleshoot a motor that won't start?
First, check for high voltage (120V or 240V) at the 5-pin power connector. If power is present, check for a 24VAC demand signal at the control board "G" terminal and inspect the 16-pin communication harness for loose pins or continuity issues.

Is the S1-324-36073-446 compatible with my existing blower wheel?
This motor is designed to match the specific shaft diameter and torque requirements of the OEM blower assembly. Always inspect the blower wheel for debris or imbalance before installing the new motor to prevent premature bearing failure.

Does this motor require a capacitor?
No, ECM motors utilize an integrated electronic control module to manage phase and timing, so a standard run capacitor is not required.
