The Goodman B1376853 Motor Mount Arm is a genuine OEM bracket that secures the blower motor assembly within Goodman and Amana gas furnaces, including the ACVC80803BXBC. A solid, correctly-shaped mount arm keeps the blower motor properly aligned in the housing, minimizing vibration and noise and extending motor and bearing life.
The OEM B1376853 arm matches the factory mounting hole pattern and motor band geometry exactly, so the blower seats correctly the first time. Generic or repurposed brackets often introduce misalignment that causes vibration, premature bearing wear, and rattling.
Easy to Moderate — Replacement involves removing the blower assembly, transferring the motor to the new mount, and reinstalling. Disconnect power before servicing and verify the blower spins freely after reassembly. A DIYer with basic tools can complete this; a technician is recommended if you are unfamiliar with blower removal.
Confirm fitment against your furnace's parts diagram before ordering.
