York S1-373-08070-700 Motor

The York S1-373-08070-700 Blower Motor is a heavy-duty, 3/4 HP OEM replacement motor designed for high-static pressure applications in residential and light commercial HVAC systems. Operating at 208-230V and a rated speed of 1075 RPM, this permanent split capacitor (PSC) motor features a multi-speed design for precise airflow balancing and system efficiency. It is engineered with a standard 48-frame diameter and uses high-grade ball bearings to handle the thermal demands of continuous furnace or air handler operation. This direct drive blower motor ensures drop-in compatibility with York, Luxaire, and Coleman equipment, maintaining the integrity of the original air delivery specifications. For contractors, this HVAC blower motor replacement provides a reliable solution for restoring CFM performance without the need for mounting modifications or complex wiring adjustments. Ensure a new 5uF/370V run capacitor is installed to maintain proper torque and winding longevity.

• OEM Precision: Genuine York replacement ensures correct shaft length and belly-band fitment.
• Multi-Speed Versatility: 3-speed taps allow for optimized heating and cooling CFM adjustments.
• Standard 48-Frame: Simplifies installation across a wide range of furnace and modular blower housings.
• High Temperature Winding: Rated for Class B insulation to withstand internal cabinet heat.

Common Questions

Is the York S1-373-08070-700 a direct substitute for generic 3/4 HP motors?
While generic motors may share horsepower and voltage, this OEM part matches the specific torque curve and shaft dimensions required to maintain the design airflow of York manufactured units.

What capacitor is required for this 1075 RPM motor?
This motor typically requires a 10 MFD or 5 MFD 370V capacitor; always verify the rating on the new motor's nameplate prior to energizing the circuit.

Can this motor be used in 115V systems?
No, this is a 208-230Vac component. Applying 115V will result in low torque and eventual winding failure, while a 460V application will cause immediate motor burnout.
