Lennox 68659 Fan Blade

The Lennox 68659 Fan Blade is a critical condenser motor component engineered for high-static efficiency in residential and light commercial Lennox HVAC systems. This heavy-duty aluminum fan blade features a 4-blade configuration designed to optimize CFM output while maintaining structural integrity under high RPM loads. It is a direct OEM HVAC replacement part often required when excessive vibration, blade pitching, or corrosion compromises the heat transfer efficiency of the outdoor coil. Ensuring proper condenser fan pitch and balance is essential for preventing premature motor bearing failure and maintaining system head pressures within nameplate specifications. This 20-inch fan blade is built to withstand rigorous outdoor environments, providing the precise airflow necessary for effective refrigerant cooling in Lennox cooling units. For field technicians, verifying the CW rotation and bore diameter is vital to ensure seamless integration with the existing motor shaft and consistent cooling performance during peak demand cycles.

• Optimized Airflow Dynamics: Precision-balanced blade design reduces turbulence and noise levels while maximizing heat dissipation across the condenser coils.
• Corrosion-Resistant Construction: Fabricated from high-grade aluminum to resist environmental wear and prevent weight imbalances caused by oxidation.
• Direct OEM Fitment: Eliminates the guesswork associated with universal parts, ensuring the condenser fan motor operates within its intended amperage range.
• Structural Durability: Engineered to handle high starting torque and continuous operation without blade flattening or mechanical fatigue.

What are the signs that a Lennox 68659 fan blade needs replacement?
Technicians should look for visible stress fractures, bent blades, or excessive vibration during the start-up cycle. If the fan motor is drawing high amps but airflow is restricted, the blade pitch may be compromised.

Is this blade compatible with other HVAC brands?
While designed specifically as a Lennox 68659 replacement, compatibility depends on bore size, diameter, and rotation. It is always recommended to stick with OEM specifications to ensure the motor's service life is not shortened by improper load.

Does the rotation direction matter for this specific part?
Yes, the Lennox 68659 is set for a specific rotation (typically Clockwise). Installing a blade with the incorrect rotation will result in reversed airflow, causing the system to trip on high-pressure limits.
