Carrier LA01RA321 Fan Blade

The Carrier LA01RA321 Fan Blade is a high-performance OEM replacement condenser fan blade engineered for precision airflow in Carrier, Bryant, and Payne residential and light commercial condensing units. This 20-inch diameter 3-blade fan features a 28-degree pitch and clockwise (CW) rotation (facing the hub), optimized to maintain design head pressure by moving the exact CFM required for high-efficiency heat transfer. Constructed from durable aluminum, this blade resists corrosion and fatigue, ensuring long-term balance and reduced vibration in high-duty cycle environments.

A critical spec for field technicians is the 1/2-inch bore, which is positioned on the intake side for proper motor shaft alignment. This HVAC replacement fan blade is the factory-authorized solution for restoring factory-spec cooling performance when your current blade is warped, pitted, or out of balance. Using genuine Carrier parts like the LA01RA321 ensures your condenser fan motor operates within its rated amperage, preventing premature motor failure and maintaining the operational integrity of the entire air conditioning system.

Key Benefits:

• Precision Airflow: The 28-degree pitch is specifically calibrated for Carrier condensing units to maximize heat dissipation.
• OEM Compatibility: Seamlessly replaces Carrier part LA01RA321 without requiring modifications to the motor shaft or fan shroud.
• Durability: Rugged aluminum construction provides superior resistance to environmental stressors and mechanical wear.
• Balanced Performance: Factory-balanced design minimizes mechanical vibration, protecting the condenser motor bearings.

Common Questions:

How do I verify the rotation for this fan blade?
The LA01RA321 is a clockwise (CW) rotation blade. Rotation is determined by looking at the hub or discharge side; always confirm the rotation of your existing motor before installation to avoid reverse airflow issues.

Will this blade fit a 1/2-inch motor shaft?
Yes, this blade features a standard 1/2-inch bore. It is designed for a secure fit on 1/2-inch shafts commonly found in Carrier and Bryant condenser fan motors.

What happens if I use a fan blade with a different pitch?
Using a non-spec pitch will change the load on your motor. A higher pitch increases the amp draw and can burn out the motor, while a lower pitch reduces airflow and leads to high head pressure. The 28-degree pitch of the LA01RA321 is required for specific Carrier HVAC models.
