Westinghouse 668927 Motor Mount Arm Downflow Furnace

Product Description

The WESTINGHOUSE 668927 is a replacement motor mount arm designed for downflow gas furnaces. This structural component secures the blower motor in the correct position within the furnace cabinet, maintaining proper alignment between the motor shaft and blower wheel. Correct motor positioning is essential for efficient airflow delivery and to prevent premature bearing wear. The 668927 is installed by licensed HVAC technicians during routine motor replacement service or when the existing mount arm shows signs of fatigue, cracking, or deformation.

This motor mount arm is specifically used on Westinghouse G6RC, G6RD, G6RK, and G6TK series downflow furnaces. Downflow units are commonly installed in homes where the supply air is discharged downward into the duct system, such as attic-mounted or main-floor configurations with a crawlspace or basement plenum below. Replacing a damaged or worn mount arm restores proper motor support and reduces vibration-related noise during furnace operation.
