Goodman B1086771S Condenser Fan Blade — 18" X-Series

The genuine Goodman B1086771S is an 18-inch X-Series condenser fan blade engineered as a direct-fit replacement for the Goodman GMT090-3 and compatible units. A cracked, bent, or corroded fan blade causes vibration, noise, reduced airflow, and premature motor wear. This factory-balanced blade restores smooth, quiet operation and the correct CFM your system was designed for.

Specifications

Diameter: 18 inches
Series: X-Series condenser fan blade
Application: Outdoor condenser fan
Fits: Goodman GMT090-3 and compatible units
OEM Part Number: B1086771S

OEM vs. Generic

The OEM Goodman B1086771S is precision-balanced to match the original pitch, bore, and rotation, preventing the vibration and motor-bearing damage that off-spec generic blades commonly introduce. For a spinning part mounted directly to your motor shaft, factory balance is not optional — OEM protects the motor investment above it.

Installation Difficulty

Easy–Moderate (2/5). Roughly 30 minutes. Disconnect power, remove the fan grille, loosen the set screw on the motor shaft, swap the blade, and confirm proper hub orientation and clearance before re-securing. Verify the blade spins freely without contacting the shroud.
