Carrier LA01AA015 Fan Blade

The Carrier LA01AA015 Fan Blade is a critical OEM replacement condenser fan engineered for precise airflow management in residential and light commercial condensing units. This 18-inch diameter fan blade features a 28-degree pitch and a 4-blade configuration designed to optimize heat rejection while maintaining quiet operation. Built for durability, it utilizes a 1/2-inch bore specifically positioned on the intake side to ensure proper seating on the motor shaft. With a clockwise (CW) rotation, this propeller-style blade matches factory specifications for models like the 541DJX036000AAAA and various 50CP and 585HJW series units. Replacing a wobbling or stress-cracked HVAC condenser fan with this genuine component prevents premature motor bearing failure and maintains the subcooling levels required for efficient system performance. Professionals should verify the hub position and rotation direction before installation to ensure the Carrier fan blade 18 inch provides the necessary static pressure for the coil.

• Optimal Airflow Efficiency: The 28-degree pitch is precision-calibrated to move the exact CFM required for high-efficiency heat exchange without overloading the fan motor.
• Reduced Vibration: Being a factory-authorized part, it arrives balanced to minimize mechanical stress on the motor shaft and housing.
• Corrosion Resistance: Constructed with high-grade materials to withstand outdoor environmental exposure and high-velocity debris contact.
• Universal Compatibility: Fits standard 1/2-inch motor shafts, making it a reliable choice for Carrier, Bryant, and Payne equipment.

How do I confirm the rotation of my old blade?
The LA01AA015 is a clockwise (CW) rotation blade. Always determine rotation by looking at the discharge side of the fan (facing the hub).

What are the signs that I need to replace my fan blade?
Check for hairline cracks near the rivets or hub, and look for signs of "throwing a shoe" (uneven bending) which causes excessive vibration and noise during startup.

Will this work with a 5/8-inch motor shaft?
No, this specific part is machined for a 1/2-inch bore. If you have upgraded your motor to a larger shaft size, this blade will not be compatible.
