Ruud 51-104671-01 Furnace Blower Motor 1/2 Hp Direct Drive

Product Description

The RUUD 51-104671-01 is a direct-drive blower motor designed for residential gas furnace applications. Rated at 1/2 HP and 1075 RPM, this 4-speed motor operates on 120 VAC, 60 Hz, single-phase power with a full load amperage of 6.3 A and a locked rotor amperage of 12.9 A. It uses a 48 frame construction and supports both shell-band and shell-screw mounting configurations. Rotation is counter-clockwise (CCW). Licensed HVAC technicians install this motor as part of blower assembly service or motor replacement on gas furnace systems.

This motor is rated for indoor use and is specified for the R92PA, R95PA, and R96PA series Rheem and Ruud gas furnaces. It serves as an OEM-style replacement for Rheem, Ruud, and Weather King models. The 4-speed winding configuration allows the motor to support multi-stage airflow demands typical in residential gas furnace installations. It may also be suitable for aftermarket retrofit applications where a 48 frame, direct-drive blower motor with matching electrical characteristics is required.
