Nordyne 667359R Fan Blade
The Nordyne 667359R Fan Blade is a critical replacement component for condenser fan motor assemblies in specialized HVAC residential and light commercial units. As a direct replacement for the legacy 667359 part, this heavy-duty 3-blade fan is engineered to withstand the rigorous duty cycles of external condensing units. With a 23-inch diameter and a precisely pitched 23-degree blade angle, it ensures optimal static pressure and volumetric airflow for high-efficiency heat exchange. The 1/2-inch bore hub is designed for a secure fit on standard condenser motor shafts, utilizing clockwise (CW) rotation to maintain the necessary vertical discharge profile required by Nordyne furnace and AC systems.
Technical specifications for this HVAC replacement part focus on structural integrity and balance. The aluminum blade construction resists corrosion, preventing the common oxidation issues that lead to fan imbalance and subsequent motor bearing failure. For technicians performing AC system maintenance, replacing a warped or pitted blade with the OEM Nordyne 667359R is the most effective way to eliminate vibration noise and restore factory-spec amperage draw on the outdoor fan motor.

Key Benefits
- Optimized Airflow: The 23-degree pitch provides the exact cubic feet per minute (CFM) required to keep condenser coil temperatures within safe operating limits.
- Direct OEM Alignment: Eliminates the guesswork of aftermarket universal blades, ensuring correct hub depth and blade clearance within the fan shroud.
- Reduced Mechanical Stress: Precision balance lowers vibrational harmonic distortion, extending the service life of the fan motor and mounting brackets.
- Enhanced Efficiency: Restores original heat rejection capabilities, improving the SEER rating performance of the integrated cooling system.
Is the Nordyne 667359R compatible with other Miller or Intertherm units?
Yes, this blade is frequently utilized across the Nordyne family of brands, including Intertherm and Miller mobile home split-system condensers. Always verify the CW rotation and bore size against the existing motor nameplate data.
What are the signs that a 23-inch fan blade needs replacement?
Contractors should look for excessive unit vibration, stress fractures near the fan hub, or visible pitch deformation. Any deviation from the 23-degree angle will cause the motor to run hot and decrease the subcooling efficiency of the refrigerant circuit.
Does this part include the set screw for the 1/2-inch shaft?
Most units ship with the set screw pre-installed in the hub, but it is standard practice for technicians to inspect the motor shaft flat for burrs before securing the replacement fan blade.
