Amana-Goodman 20414601 Fan Blade

The Amana-Goodman 20414601 Fan Blade is a critical replacement component designed for high-static pressure applications in residential and light commercial HVAC systems. This condenser fan blade features a 3-blade configuration with a 22-inch diameter and a 26-degree pitch, optimized for maximum CFM delivery across the coil while maintaining low decibel levels. Engineered for a 1/2-inch shaft diameter, this direct-drive fan blade is a factory-authorized part for many Goodman heat pumps and Amana condensing units. It is constructed from heavy-gauge aluminum to resist corrosion and ensure structural integrity under constant thermal cycling. When replacing the 20414601 propeller, technicians should verify the rotation direction (CCWLE) and ensure the set screw is torqued to manufacturer specifications on the motor shaft flat. This part is essential for maintaining proper refrigerant head pressure and preventing compressor overheat in packaged unit air conditioners and split systems.

Key Benefits for HVAC Professionals

• Optimized Airflow: Precision-pitched blades ensure consistent air volume for efficient heat transfer.
• Direct Compatibility: Exact replacement for 20414601S, reducing installation time on Goodman and Amana equipment.
• Durable Construction: High-grade aluminum prevents blade fatigue and balances the rotational load on the condenser motor.
• Factory Balanced: Reduces vibration and noise, extending the service life of the motor bearings and mounting brackets.

Common Questions & Installation Tips

What causes this fan blade to fail?

Common failure points include stress fractures near the hub, electrolyte corrosion in coastal environments, or damage from debris hitting the condenser guard. Imbalance often leads to excessive vibration, which can damage the motor.

Is this compatible with 1/2" or 5/8" motor shafts?

The 20414601 is designed specifically for a 1/2-inch motor shaft. Always check the shaft diameter and the flat spot before tightening the hub set screw.

How do I verify the correct rotation?

This blade operates with a counter-clockwise lead edge (CCWLE) rotation. Installing a fan blade with incorrect rotation will cause high-pressure trips and lead to compressor failure.
