Rheem-Ruud 51-100998-19 Motor
The Rheem-Ruud 51-100998-19 is a high-performance 1/3 HP condenser fan motor engineered for drop-in compatibility with specific Rheem, Ruud, and WeatherKing outdoor units. This 1075 RPM replacement motor operates on 208-230V single-phase power, drawing 2.0 amps at full load. Built with a NEMA 48 frame and a totally enclosed enclosure, it provides superior protection against environmental debris and moisture, ensuring reliable heat transfer in demanding conditions. As a Permanent Split Capacitor (PSC) motor, it requires a 5.0 MFD / 370V capacitor for optimal torque and efficiency. The unit features CCW rotation (lead end), a sleeve bearing design for quiet operation, and a standard 1/2" x 2 3/4" shaft for secure fan blade attachment. Designed for shell-band mounting, this motor facilitates rapid field installation, maintaining the strict airflow requirements of the OEM refrigeration cycle.
Key Benefits
- OEM Precision: Direct replacement for Rheem 51-100998-19, ensuring exact physical fit and electrical matching without bracket modification.
- Enhanced Durability: The totally enclosed motor housing prevents dust and water ingress, extending the service life of the internal windings.
- Quiet Operation: The high-grade sleeve bearing system reduces vibration and decibel levels compared to lower-quality aftermarket alternatives.
- Efficient Performance: Rated at 1075 RPM, it delivers the consistent static pressure necessary for optimal condenser coil cooling.
Common Questions
What capacitor does the 51-100998-19 require?
This motor is designed to work with a 5 MFD / 370V run capacitor; always replace the capacitor when installing a new motor to ensure proper starting torque.
Is this motor reversible?
No, this specific model is a CCW rotation (Counter-Clockwise) unit as viewed from the lead end/opposite shaft end. Verify your fan blade pitch before installation.
Can I use this in an open-ventilated application?
While possible, this is a Totally Enclosed Enclosure motor specifically rated for outdoor condenser units where exposure to rain and debris is expected.
