Goodman Amana Janitrol B1086756S Fan Blade | 18" Diameter 3 Blade 1/2" Bore 22° Pitch CW

The B1086756S is a precision-engineered OEM Service Pack condenser fan blade serving as the primary airflow component for compact Goodman, Amana, and Janitrol outdoor condensing units. Acting as the mechanical "lungs" of the system, this 18-inch blade functions as the "brain" of heat dissipation, pulling air across the condenser coils to maintain optimal refrigerant pressures in smaller footprint 1.5 to 2.5-ton units. Engineered specifically for high-static pressure in tight cabinets, this blade is calibrated to move maximum CFM (Cubic Feet per Minute) while keeping the motor’s amperage within safe factory limits. Utilizing this genuine Service Pack replacement ensures your system maintains its factory-rated efficiency and prevents the premature motor bearing failure or excessive vibration common with uncertified aftermarket alternatives.

Key Features

• Exact OEM Service Pack Match: A direct factory replacement for B1086756S, ensuring the weight, balance, and blade geometry perfectly align with Goodman’s original system engineering.
• Compact 18" Diameter: Specifically designed for "mini" or space-saving outdoor cabinets where larger 22-inch or 26-inch blades will not fit.
• High-Volume 22° Pitch: The aggressive 22-degree blade angle is factory-calibrated for maximum airflow, fixing specific "high head pressure" faults in smaller AC and heat pump systems.
• Clockwise Rotation: Specifically pitched for CW rotation (viewed from the discharge side), ensuring the correct vertical airflow direction required for top-discharge units.
• Safety Balanced Construction: Each 3-blade 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 18-inch units have tighter tolerances, positioning the blade too high or too low on the motor shaft can cause air recirculation and significantly decrease 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.
