Carrier LA680546 Fan Blade

The Carrier LA680546 Fan Blade is a critical OEM replacement condenser fan blade designed for large-tonnage commercial and residential condensing units. This 26-inch diameter component features a 4-blade configuration with a 1/2-inch bore diameter and is engineered for CCW (counter-clockwise) rotation. When performing a swap, contractors should note that the LA680546 is the direct Carrier LA01RW026 replacement, maintaining the exact pitch and balance required to prevent motor bearing premature wear. Constructed from heavy-duty aluminum with a galvanized steel hub, this blade ensures optimal HVAC airflow efficiency even under high static pressure conditions. Whether you are addressing a noisy outdoor AC unit or a complete blade failure, installing this genuine Carrier part restores factory-spec heat transfer and protects the compressor from high-head pressure faults. Verify the set screw torque and blade depth within the shroud to ensure peak performance and condenser motor compatibility.

• Direct OEM Fit: Drop-in replacement for the LA01RW026, eliminating the need for shaft modifications or hub adjustments.
• Engineered Aero-Pitch: The 4-blade design is optimized for maximum CFM at standard RPMs to ensure consistent head pressure regulation.
• Dynamic Balancing: Precision-balanced at the factory to minimize vibration, extending the service life of the condenser fan motor.
• Corrosion Resistance: High-grade materials designed to withstand harsh outdoor environments and coastal salt spray.

Common Installation Questions

What is the orientation of this blade?
This is a Lead-Edge CCW rotation blade. Always verify rotation from the discharge side (top-down) before securing the set screw to the flats of the 1/2" motor shaft.

Can this replace a plastic fan blade of the same diameter?
Yes, provided the 26-inch diameter, 1/2" bore, and rotation match. The LA680546 provides structural rigidity that prevents "flexing" common in vintage polymer blades under high heat loads.

Why is my fan blade vibrating after installation?
Ensure the hub is seated on the flat portion of the shaft and the 1/2-inch bore is not loose. If vibration persists, check the motor shaft for runout or the motor mounts for fatigue.
