Goodman Amana Janitrol B1086775SP Fan Blade | 21.5" Diameter 3 Blade 1/2" Bore 24° Pitch CCW

The B1086775SP is a high-efficiency OEM condenser fan blade engineered as the primary airflow component for Goodman, Amana, and Janitrol outdoor condensing units. Acting as the mechanical "lungs" of the system, this blade serves as the "brain" behind heat rejection, pulling ambient air across the condenser coils to maintain critical refrigerant pressures. Designed specifically for 1.5 to 3-ton residential units, this 21.5-inch blade features a steep 24-degree pitch calibrated to move maximum CFM (Cubic Feet per Minute) while keeping the motor’s amperage within factory limits. Utilizing this genuine Service Pack replacement ensures your system maintains its factory-rated SEER efficiency and prevents the premature motor failure or excessive vibration common with uncertified aftermarket alternatives.

Key Features

• Exact OEM Service Pack Match: A direct factory replacement for B1086775SP, ensuring the weight, balance, and blade geometry perfectly align with Goodman’s original system engineering.
• High-Volume 24° Pitch: The aggressive 24-degree blade angle is factory-calibrated for maximum airflow, specifically fixing "high head pressure" faults in dense outdoor cabinets.
• Durable Aluminum Construction: Manufactured from high-grade aluminum to resist deformation and withstand continuous outdoor operation in high-humidity and corrosive environments.
• Counter-Clockwise Rotation: Specifically pitched for CCW rotation (viewed from the discharge side), ensuring the correct vertical airflow direction required for top-discharge units.
• Safety Balanced Assembly: Each 3-prong assembly is factory-balanced to protect the condenser motor from centrifugal stress, fixing common "shaking" or mechanical humming issues.

🛠️ HVAC Depot Pro Tip

Before removing the old blade, take a high-resolution picture of the original blade's depth within the fan shroud (venturi). Because a 24-degree pitch blade creates significant lift, improper positioning on the motor shaft can cause air turbulence and "hunting," which decreases cooling capacity. Use a piece of emery cloth to clean all rust off the motor shaft before installation. Always tighten the hub's set screw onto the "flat" side of the motor shaft only; tightening onto the rounded side will lead to a loose blade and potential damage to the condenser coil.
