Nordyne Fan Motor 621918 1/5 HP 1075 RPM

Nordyne / Miller / Nortek 621918 Condenser Fan Motor | OEM

The Nordyne 621918 is a genuine factory-authorized condenser fan motor designed for residential outdoor air conditioning and heat pump units. As an Original Equipment Manufacturer (OEM) component, it is manufactured by Zhongshan Broad-Ocean Motor Co (Model Y6S620C53) to meet the precise cooling requirements of Nortek Global HVAC systems.

This motor is characterized by its 42Y frame (5" diameter), which is more compact than the standard 48Y frame found in many other units. It features a Permanent Split Capacitor (PSC) design for high starting torque and energy efficiency, ensuring reliable heat dissipation from your outdoor coil even during extreme summer temperatures.

Why Choose a Genuine Nortek OEM Motor?

  • Compact 42Y Frame: Specifically built for units with narrow motor mounts where a standard 5.6" motor will not fit, ensuring a direct "drop-in" installation without mounting modifications.
  • Precision Airflow: Rated at 1075 RPM, this motor is matched to the specific fan blade pitch of your unit to maintain factory-spec head pressure and system efficiency.
  • All-Weather Durability: Features a closed enclosure and high-quality internal bearings designed for long-term outdoor exposure in both "shaft-up" and "shaft-down" configurations.
  • Exact Electrical Specs: The 1.15/1.18A draw is perfectly balanced for your existing contactor and control board, preventing the nuisance electrical trips often seen with universal alternatives.

  • Continental US Shipping: We offer reliable shipping rates for all orders delivered within the Continental United States.
