Rheem-Ruud 51-23055-12 Condenser Motor

The Rheem-Ruud 51-23055-12 Condenser Motor is a high-performance 1/5 HP HVAC fan motor engineered for precision cooling in residential and light commercial outdoor units. This 825 RPM condenser motor operates on 208-230V single-phase power and features a 1.3 Amp draw, providing an efficient OEM motor replacement solution for Rheem, Ruud, and WeatherKing equipment. Built with a NEMA 48 frame size and a totally enclosed air over (TEAO) enclosure, this motor is designed to withstand the harsh environment of an outdoor condenser section while maintaining thermal protection and operational stability.

This permanent split capacitor (PSC) motor is the verified direct replacement for 51-21276-02 and 51-22015-01. It utilizes a reversible rotation design and multiple mounting options, including shell-band, shell-screw, and thru-bolt configurations, ensuring compatibility with a variety of fan blade depths and shroud clearances. The 1/2" x 3 3/4" shaft is sized for standard condenser fan blade hubs. When replacing this unit, technicians should verify the capacitor (typically 5 MFD or 7.5 MFD at 370V) to ensure the Rheem-Ruud 51-23055-12 maintains its specified torque and speed profiles without overheating.

• Direct Fit Compatibility: Seamlessly replaces legacy part numbers 51-21276-02 and 51-22015-01 without bracket modifications.
• Versatile Mounting: Includes three primary mounting styles (Shell-Band, Shell-Screw, Thru-Bolt) to accommodate diverse condenser chassis designs.
• Efficient Performance: 825 RPM low-speed operation reduces acoustic noise while providing consistent static pressure for heat transfer.
• Durable Construction: Features sleeve bearings and a totally enclosed housing to protect internal windings from moisture and debris.
• Multi-Brand Support: Found in various Rheem, Ruud, WeatherKing, and Corsaire AC and Heat Pump units.

What capacitor does the 51-23055-12 require?
Standard field specifications for this 1/5 HP motor typically require a 5 MFD or 7.5 MFD / 370V run capacitor; always check the motor nameplate during installation for the exact microfarad rating.

Is this motor reversible?
Yes, the 51-23055-12 features reversible rotation, allowing for either Clockwise (CW) or Counter-Clockwise (CCW) Lead End orientation to match your specific fan blade pitch.

Can this replace a 1075 RPM motor?
No, this motor is rated for 825 RPM. Substituting a 1075 RPM motor with an 825 RPM unit will lower airflow and may cause high-head pressure issues in the refrigeration circuit.
