Amana-Goodman B1086749 Fan Blade

The Amana-Goodman B1086749 Fan Blade is a genuine OEM Goodman/Janitrol/Amana condenser motor fan blade specifically engineered for high-static residential and light commercial condensing units. This 20-inch 3-blade fan features a 30-degree pitch and a standard 1/2-inch motor shaft bore, ensuring a precise fit on compatible factory motors. Utilizing a counter-clockwise (CCW) rotation (when the set screw is positioned downward), this component is designed to maintain target head pressures by optimizing airflow across the condenser coils. For field technicians, verifying the B1086749 Goodman replacement blade specifications is critical for preventing motor overload and premature bearing failure. This heavy-duty aluminum blade is a direct-fit solution for damaged or out-of-balance assemblies, restoring the system's thermal exchange efficiency and operational decibel levels to original factory standards. Always confirm the motor's RPM and directional rotation before installation to ensure performance stability.

• Direct OEM Compatibility: Guaranteed fit for specific Goodman, Amana, and Janitrol condensing units, eliminating the balance issues associated with universal aftermarket blades.
• Precision Airflow: The 30-degree pitch is calibrated to move the exact CFM required for proper heat dissipation without straining the condenser fan motor.
• Industrial Build Quality: Constructed for harsh outdoor environments to resist corrosion and maintain structural integrity under high-velocity stress.
• Reduced Vibration: Factory-balanced design minimizes mechanical noise and protects the motor’s internal components from excessive oscillation.

• How do I confirm the rotation of the B1086749? This blade is counter-clockwise (CCW) rotation when viewed with the set screw facing down. Check your existing motor’s lead data plate to ensure a match.
• Will this fit a 5/8-inch motor shaft? No, this blade is designed strictly for a 1/2-inch bore. Using a bushing or force-fitting the hub can lead to catastrophic failure.
• Why is the 30-degree pitch important? The pitch determines the air volume moved per revolution; installing a blade with an incorrect pitch can over-amp the motor and cause it to trip on thermal overload.
