York S1-FHM3466 Motor

The York S1-FHM3466 is a heavy-duty, multi-horsepower direct drive blower motor engineered for high-static residential and commercial air handlers. This 5.6-inch diameter PSC motor provides a versatile output range from 1/5 HP to 3/4 HP, making it a critical truck-stock item for immediate furnace and modular housing unit repairs. Operating on a standard 115V single-phase power supply at 1075 RPM, this unit features a 4-speed tap configuration to fine-tune system CFM and optimize airflow across various ductwork geometries.

Built with an Open Air Over (OAO) enclosure, the S1-FHM3466 utilizes the moving airstream for thermal management, ensuring stable performance during extended run cycles. The reversible rotation capability eliminates the need for multiple stock numbers, allowing technicians to configure clockwise or counter-clockwise operation in the field. This OEM York replacement motor is frequently cross-referenced with MARS 10466 and Packard 45470 for use in HVAC blower assembly applications where reliability and precise speed control are non-negotiable.

• Multi-Horsepower Versatility: Replaces 1/5, 1/4, 1/3, 1/2, and 3/4 HP motors, reducing inventory requirements for York S1-FHM3466 service calls.
• Four-Speed Taps: Enables precise static pressure matching to enhance indoor air quality and system efficiency.
• Field Reversible: Simple lead switching allows for reversible rotation to match any existing blower wheel orientation.
• OEM Standards: Explicitly designed as a direct replacement motor for York furnace and air handler systems for seamless mechanical fit.

Is the S1-FHM3466 a suitable replacement for a single-speed motor?
Yes, while this is a 4-speed blower motor, it can be wired for single-speed operation by selecting the lead that matches your required 1075 RPM performance curve. High-speed is generally used for cooling, while lower speeds are common for heating cycles.

Does this motor require a capacitor for installation?
Yes, as a Permanent Split Capacitor (PSC) motor, it requires a run capacitor (typically 10MFD or 15MFD at 370V, depending on the specific HP setting being utilized) to operate. Ensure the capacitor rating identifies with the motor’s nameplate for the selected horsepower.

Can this motor be used in a condenser fan application?
No, this unit is an Open Air Over motor designed for indoor blower compartments. Exposure to direct rain or debris in an outdoor condenser will lead to premature failure; always use a TEAO (Totally Enclosed Air Over) motor for outdoor units.
