The Carrier LA01AB200 Fan Blade is a critical OEM replacement propeller engineered for precise airflow management in residential and light commercial condensing units. This 20-inch condenser fan blade features a 4-blade configuration with a 34-degree pitch, optimized for counter-clockwise (CCW) rotation to maintain the static pressure required for efficient heat rejection. Designed with a 1/2" bore on the discharge side, this heavy-duty fan prop ensures a secure fit on standard motor shafts, preventing the vibration and imbalance often seen with universal aftermarket alternatives. When replacing high-service-hour blades, verifying the rotation and pitch is essential to avoid motor overheating and high head pressure. This factory-authorized component is built to the exact specifications of original Carrier, Bryant, and Payne equipment, ensuring HVAC system performance and reliable outdoor unit cooling even under peak load conditions.

• Precision Pitch: The 34-degree blade angle is specifically calibrated to maximize CFM while minimizing amp draw on the condenser motor.
• OEM Compatibility: Guaranteed fit for select 559G, 50EE, and 50QQ series units, eliminating the need for field modifications or hub adjustments.
• Dynamic Balance: Factory-level balancing reduces mechanical stress on motor bearings, extending the service life of the entire fan assembly.
• Corrosion Resistance: Constructed from high-grade materials to withstand outdoor environmental exposure and prevent structural fatigue.

Common Questions

What happens if I install this CCW blade on a CW motor?
Installing a counter-clockwise fan blade on a clockwise motor will cause the air to pull in the wrong direction, leading to immediate high head pressure trips and eventual compressor failure due to lack of heat exchange.

Can this blade replace the LA01AB201?
While both are 20-inch 4-blade props, you must verify the specific pitch and motor requirements of your model. Using an incorrect blade pitch can overload the motor or fail to provide sufficient airflow for the condenser coil.

How do I ensure the 1/2" bore is seated correctly?
Always clean the motor shaft with emery cloth before installation. Ensure the set screw is tightened onto the flat portion of the shaft to prevent "slipping," which is a common cause of HVAC fan noise and shaft damage.
