The Goodman B1368016S is a genuine OEM 10-inch x 8-inch blower wheel (squirrel cage) built for Goodman WPC4349AHAA air handling systems. The blower wheel mounts on the motor shaft and moves conditioned air across the coil and through the duct system. A cracked hub, broken fins, or accumulated debris causes vibration, noise, and reduced airflow — which strains the motor and lowers cooling capacity. This factory-balanced replacement restores smooth, full-volume airflow.
The genuine Goodman OEM wheel is factory-balanced to the original blade pitch and hub bore, so it spins true at rated RPM. Generic wheels can vary in balance and bore size, introducing vibration that prematurely wears the motor bearings and creates noise. For the quietest, longest-lasting result, choose the OEM wheel.
Moderate (3 of 5). Requires removing the blower assembly, loosening the hub set screw, sliding the wheel off the shaft, and aligning the new wheel to the correct depth before tightening. Mark the shaft position and set-screw flat before disassembly. Cut power at the disconnect first. Recommended for an experienced DIYer or HVAC technician.
