Nordyne 667309R Fan Blade
The Nordyne 667309R Fan Blade is a critical replacement component engineered for specific HVAC condenser and furnace applications requiring high-velocity airflow. This 18-inch diameter propeller features a 4-blade configuration with a 30-degree pitch, optimized to maintain correct head pressure and heat transfer efficiency. Designed as the direct superseding OEM replacement for Nordyne 667309, it utilizes a 1/2-inch bore and is calibrated for clockwise (CW) rotation when viewing from the discharge side. For technicians performing HVAC blower motor repairs, ensuring the hub depth and pitch match the original condenser fan blade specifications is vital to prevent motor overloading or insufficient CFM delivery. This industrial-grade fan blade provides the structural rigidity necessary to resist flexing under high RPMs, maintaining the system's factory-rated performance profile and preventing premature motor failure caused by unbalanced airflow resistance.
Technical Specifications and Benefits
- Direct OEM Supersession: Replaces Nordyne part number 667309 with updated metallurgical standards for improved durability.
- Precision Pitch: The 30-degree blade pitch ensures optimal static pressure handling in residential and light commercial units.
- Standard Hub Size: Equipped with a 1/2" bore to accommodate standard motor shafts found in Nordyne and Miller-Intertherm equipment.

Common Installation Questions
Is the rotation reversible on this fan blade?
No, this is a fixed CW rotation fan blade. To avoid motor overheating, verify rotation direction from the lead end of the motor before installation.
Can I use this to replace a 3-blade enthusiast model?
It is recommended to only replace a 4-blade assembly with another 4-blade assembly of the same pitch to maintain the correct AMP draw and CFM requirements.
What equipment is this compatible with?
This part is commonly found in Nordyne, Intertherm, and Miller packaged units and condensers. Always verify the 18-inch diameter and 30-degree pitch against the manufacturer's data plate.
