Rheem-Ruud 51-23053-11 Motor

The Rheem-Ruud 51-23053-11 is a high-performance OEM condenser fan motor designed for heavy-duty residential and light commercial HVAC applications. This 1/3 HP condenser motor operates at a nominal 1075 RPM on a 208-230V single-phase power supply, drawing approximately 1.75 Amps at full load. Built with a NEMA 48 frame, it features a totally enclosed (TEAO) enclosure to protect internal windings from environmental debris and moisture, ensuring long-term reliability in outdoor units. The reversible rotation capability and multi-mount design—supporting shell-band, shell-screw, and thru-bolt configurations—make it an essential replacement motor for various Rheem, Ruud, and Weather King models. For optimal performance, always pair this Permanent Split Capacitor (PSC) motor with a new 5 MFD/370V run capacitor to prevent premature winding failure and ensure efficient starting torque through the 1/2" x 4 1/4" shaft.

• Versatile Mounting: Supports shell-band, shell-screw, and thru-bolt mounting patterns for maximum field compatibility.
• OEM Reliability: Genuine Protech 51-23053-11 ensures exact fitment and air-over cooling performance as specified by the manufacturer.
• Reversible Rotation: Easily adjustable lead wires allow for clockwise or counter-clockwise rotation to match existing blade pitch.
• Serviceable Design: Features a standard 48-frame diameter and 1/2-inch shaft, fitting most standard fan blade hubs.

What capacitor does the 51-23053-11 require?
This motor typically requires a 5 MFD / 370V run capacitor. It is highly recommended to replace the capacitor during motor installation to prevent overheating.

Can I use this motor to replace a 1/4 HP or 1/5 HP motor?
While this 1/3 HP HVAC motor can often replace lower horsepower ratings if the frame size and RPM match, you must verify that the fan blade pitch does not exceed the 1.75 Amp rating of this unit.

Is this motor suitable for salt-air environments?
The totally enclosed enclosure provides better protection against corrosion than open-dripproof models, though regular coil and motor housing maintenance is recommended in coastal areas.
