Nordyne 622018 Fan Motor

The Nordyne 622018 Fan Motor is a high-performance 1/4 HP 2-speed fan motor engineered for critical airflow management in residential and light commercial HVAC condenser units. Featuring a robust 48Y frame (5-5/8 inch diameter), this OEM replacement motor is the direct successor to the Nordyne 622018R, ensuring seamless mechanical and electrical compatibility. Operating at 208-230V and 1100 RPM, the motor utilizes a permanent split capacitor (PSC) design, requiring a 7.5 MFD / 370V capacitor for optimal torque and heat dissipation during high-demand cooling cycles.

Built for durability in outdoor environments, this condenser fan motor features CWLE rotation (Clockwise Lead End) and a 1/2-inch shaft diameter that fits most standard fan blades. The 2-speed functionality allows for precise airflow modulation, which is essential for maintaining system head pressure and improving overall energy efficiency across diverse Nordyne, Intertherm, and Miller equipment. Technicians should verify lead length and capacitor ratings during installation to prevent premature stator failure or overheating in restricted venting scenarios.

• Direct OEM Compatibility: Specifically designed to replace 622018R and Emerson K55HXLCM-9928 without bracket modifications.
• Industrial-Grade 48Y Frame: Provides superior structural integrity and standardized mounting for HVAC motor replacement.
• Efficient Dual-Speed Control: Enables variable airflow to match system load requirements and reduce electrical consumption.
• Thermal Protection: Includes internal safety resets to prevent winding damage during abnormal voltage spikes or stalled rotor conditions.

Is the 622018 motor compatible with older 622018R models?
Yes, the 622018 is the official direct replacement part for the 622018R and 6220180 models, maintaining the same electrical specs and 48 frame dimensions.

Does this motor require a specific capacitor?
Field data confirms this 1/4 HP motor requires a 7.5 microfarad (MFD) capacitor rated for 370 volts to maintain the correct phase shift for the start windings.

Which direction does this motor rotate?
This model is indexed for Clockwise Lead End (CWLE) rotation. Always verify the pitch of your existing fan blade to ensure proper airflow direction across the coil.
