York S1-024-17903-705 Motor

The York S1-024-17903-705 Blower Motor is a high-performance 1/4 HP replacement motor specifically engineered for York, Luxaire, and Coleman furnace and air handler assemblies. This 115V 3-speed motor operates at a nominal 1075 RPM, providing the variable airflow required to maintain static pressure across various ducting configurations. Built on a 42 NEMA frame size, it features an Open Drip Proof (ODP) enclosure designed for optimal heat dissipation during continuous duty cycles.

This Permanent Split Capacitor (PSC) motor utilizes a reliable sleeve bearing system and is configured for CCW lead end rotation. As a direct OEM replacement motor, the S1-024-17903-705 eliminates the guesswork involved with universal mounting brackets, ensuring the shaft length and diameter align perfectly with existing blower wheels. For contractors, this means reduced vibration and lower decibel ratings during operation, effectively restoring system efficiency to factory specifications.

• Direct OEM compatibility ensures precise fitment in York, Coleman, and Luxaire residential furnaces.
• 3-speed versatility allows for customizable cfm output to match heating and cooling load requirements.
• PSC architecture offers consistent torque and higher electrical efficiency compared to standard shaded-pole motors.
• 42 Frame ODP design prioritizes internal component cooling, extending the life of the single-phase 115Vac windings.

Common Questions

What is the correct rotation and orientation for this motor?
This unit is designed for CCW (Counter-Clockwise) rotation when viewed from the lead end. It is critical to verify your existing blower wheel direction to ensure proper airflow through the heat exchanger.

Does this 115V blower motor require a capacitor?
Yes, as a PSC (Permanent Split Capacitor) motor, it requires a specific run capacitor (typically verified by the rating on the motor nameplate) to start and run efficiently. Always replace the capacitor when installing a new motor to prevent premature winding failure.

Can I use this to replace a 1075 RPM motor from a different brand?
While the electrical specs (1/4 HP, 115V, 1075 RPM) may match, you must confirm the 42 NEMA frame diameter and the CCWLE rotation to ensure it fits the existing motor cradle and functions correctly in your specific air handler.
