Nordyne 904860 Motor

The Nordyne 904860 blower motor is a 1 HP heavy-duty replacement motor designed for high-static residential and light commercial HVAC applications. Operating at 115 Volts and drawing 13.0 Amps, this direct drive blower motor features 4-speed versatility to fine-tune airflow across various heating and cooling stages. With a rated speed of 1020 RPM and a standard 48-frame diameter, this permanent split capacitor (PSC) motor serves as a direct drop-in for numerous Nordyne, Intertherm, Miller, and Maytag furnace units. Contractors typically source this replacement condenser fan motor for its reliable rotation direction and high-torque performance under load. When installing, ensure the run capacitor (not included) matches the required microfarad rating to maintain thermal protection and peak efficiency. This HVAC blower motor replacement ensures stable static pressure and consistent CFM delivery across ductwork systems.

Key Performance Benefits

• Multi-Speed Flexibility: 4-speed taps allow for precise cfm adjustment based on specific ductwork requirements.
• High Torque Output: The 1 HP rating provides the necessary power for larger air handlers and high-input furnaces.
• Universal 48-Frame Design: Enables seamless mounting in standard Nordyne blower housings without bracket modification.
• Thermal Overload Protection: Built-in safety features prevent winding burnout during high-demand cycles.

Common Technical Questions

What is the frame size and shaft diameter of the 904860 motor?
This is a NEMA 48-frame motor featuring a standard 1/2-inch diameter shaft, common in most Nordyne-manufactured gas furnaces and electric air handlers.

Can I use a 3-speed motor to replace this 4-speed model?
It is recommended to maintain the 4-speed configuration of the Nordyne 904860 to ensure the control board can properly manage heating, cooling, and fan-only modes without overheating the windings.

Does this motor include the run capacitor?
Capacitors are generally sold separately; always verify the MFD rating on the new motor's nameplate to ensure compatibility with your existing or new capacitor.
