Amana-Goodman B1086771S Fan Blade

The Amana-Goodman B1086771S is a high-performance 18-inch HVAC condenser fan blade designed for critical airflow management in residential and light commercial condensing units. This 18" 3-blade fan features a precision-engineered 0.5-inch bore and is optimized for a 20-degree pitch, ensuring efficient heat dissipation and stable static pressure performance. Built to meet exact OEM specifications, this CW rotation fan blade replaces worn or unbalanced components to eliminate vibration and prevent premature motor bearing failure. Technicians should verify hub alignment and set-screw torque during installation to maintain optimal CFM output. Compatibility includes a wide range of Amana, Goodman, and Janitrol units, making it a versatile replacement condenser fan blade for restorative maintenance. Relying on OEM HVAC parts like the B1086771S ensures the system operates within its original design parameters, maintaining the necessary thermal exchange rates for the refrigerant cycle.

• Precision Balanced: Minimized vibration reduces mechanical stress on the condenser fan motor.
• OEM Specifications: Guaranteed fitment for specific 18-inch 3-blade configurations with a 1/2" shaft.
• Optimized Pitch: 20-degree blade angle provides consistent airflow (CFM) through the coil fins.
• Durable Construction: Engineered to withstand high-velocity outdoor environments and corrosive elements.

What is the correct rotation for the B1086771S?
This component is a clockwise (CW) rotation blade when viewed from the discharge side (lead end of the motor).

Will this blade fit any 18-inch HVAC motor?
While it fits standard 0.5-inch shafts, you must verify the pitch and rotation match your specific Goodman or Amana model to avoid motor overheating.

How do I ensure the blade is installed at the correct depth?
Measure the original blade’s position on the shaft before removal; incorrect vertical placement can significantly reduce heat transfer efficiency.
