The Garland 1613901 Oven Blower Wheel is a counterclockwise rotating airflow component measuring 10-3/4 inches in diameter and 3-1/8 inches wide. Its 5/8-inch bore fits the specified motor shaft, while the smooth hub and single set screw secure the wheel within the blower assembly. The concave-back design corresponds to the intended oven configuration. Installed inside compatible Garland equipment, the wheel rotates with the motor to circulate air through the oven chamber.
