Goodman B1086756S 18" Condenser Fan Blade

The B1086756S is a genuine OEM 18-inch condenser fan blade built for the Goodman GMT090-3A package unit. The fan blade mounts to the condenser motor shaft and moves outdoor air across the coil to dissipate heat from the refrigerant. When a blade is bent, chipped, or out of balance, you'll see high head pressure, reduced cooling capacity, vibration, and accelerated wear on the fan motor bearings.

Specifications

Blade diameter: 18 inches
Material: Corrosion-resistant aluminum
Balance: Factory-balanced for low vibration
Fits: Goodman GMT090-3A package units
OEM Part Number: B1086756S

OEM vs. Generic

The OEM B1086756S is pitched and balanced to the factory airflow spec with a matched shaft bore and set screw, delivering correct CFM and quiet, vibration-free operation. Generic universal blades may need field balancing and re-pitching and can shorten motor life. For a package unit this size, OEM is recommended.

Installation Difficulty

Moderate (2/5). Kill power at the disconnect, remove the top grille, loosen the set screw, and slide the old blade off. Install the new blade at the same shaft height and orientation, then tighten the set screw on the flat. Basic hand tools required; verify power is off before starting.
