Nordyne 667345R Blade

The Nordyne 667345R is a high-precision 18-inch HVAC condenser fan blade engineered for clockwise (CW) rotation. Designed as a direct OEM replacement for select Nordyne, Nortek, and Frigidaire air conditioning units, including models CSA4BD024KB and CSA4BD030KB, this component ensures critical airflow specifications are met for optimal heat exchange. A compromised or unbalanced blade can lead to excessive vibration, premature motor bearing failure, and reduced system efficiency. This 18" CW Blade features a robust aluminum construction with a 1/2-inch bore, specifically pitched to maintain the designated CFM output required by high-efficiency residential condensing units. When performing maintenance, technicians should verify the blade pitch and rotation direction against the data plate of the condenser motor to ensure a precise match. Replacing a damaged blade with this authentic replacement fan blade restores the aerodynamic balance needed to preserve the lifespan of the condenser fan motor and maintain stable head pressures during peak cooling cycles.

Key Benefits

• OEM Compatibility: Specifically engineered for Nordyne HVAC parts compatibility, ensuring a proper fit on 1/2" motor shafts.
• Enhanced Airflow: The 18-inch diameter and optimized pitch maximize condenser fan blade efficiency for superior heat dissipation.
• Durable Construction: Heavy-duty aluminum build resists corrosion and deformation under high-static pressure environments.
• Vibration Reduction: Factory-balanced design minimizes mechanical stress on the motor and reduces ambient noise levels during operation.
• Improved Efficiency: Helps maintain manufacturer-specified energy efficiency by ensuring consistent cubic feet per minute (CFM) delivery.

Common Questions

How do I verify if this 18-inch blade is correct for my unit?
Always cross-reference the part number 667345R with your unit’s service manual or check the rotation on the motor's data plate. This blade is for clockwise (CW) rotation as viewed from the discharge side.

What happens if I install a fan blade with the wrong pitch or rotation?
Installing an incorrect blade will reverse airflow or significantly drop static pressure, leading to high head pressure, compressor overheating, and potential system lockout.

Should I replace the motor and capacitor at the same time?
If the previous blade failed due to excessive wobbling or a seized motor, it is best practice to inspect the motor bearings and test the run capacitor to ensure the new blade operates under optimal mechanical conditions.
