Nordyne 667312R Fan Blade

As a seasoned technician, you know that performance in the field depends on using exact specifications when swapping out a condenser fan. The Nordyne 667312R Fan Blade is the direct engineering replacement for the older Nordyne 667312 model, specifically designed to maintain the factory-standard static pressure and CFM requirements of your unit. This 24-inch diameter fan blade features a 4-blade aluminum construction and is indexed for counter-clockwise (CCW) rotation, ensuring optimal heat rejection across the condenser coils. With a 1/2 inch bore and a steep 28-degree pitch, this part is built to move a high volume of air while minimizing motor stress. Whether you are servicing a Nordyne condenser or an Intertherm heat pump, matching the OEM fan blade specifications is critical to preventing premature motor failure and maintaining high-efficiency cooling performance. Ensure the hub is securely torqued to the motor shaft during installation to eliminate vibration and preserve the balance of the assembly.

• Direct OEM Replacement: Replaces Nordyne part 667312 with identical mounting footprint and airflow profile.
• Precision Airflow: The 28-degree blade pitch is engineered to maximize heat transfer in residential HVAC systems.
• Heavy-Duty Construction: Durable aluminum blades resist corrosion and maintain structural integrity under high RPMs.
• Universal Compatibility: Fits Nordyne, Miller, and Intertherm units requiring a 24" Dia 4 Blade setup with a 1/2" bore.

Common Questions

What is the correct rotation for this fan blade?
This blade is designed for CCW (Counter-Clockwise) rotation. Always verify rotation from the discharge side of the fan to ensure correct airflow direction through the condenser.

Does this include the hub and set screw?
Yes, the Nordyne 667312R comes with a 1/2" diameter bore hub and the required set screw for secure attachment to the condenser motor shaft.

Can I use this if my original blade had a different pitch?
It is highly recommended to match the 28-degree pitch exactly. Using a different pitch can change the motor's amp draw, potentially leading to overheating or shortened motor life.
