The Goodman B1376853 is a genuine OEM blower motor mount arm engineered for the ACVC80603BXBD gas furnace and compatible Goodman/Amana variable-capacity models. This bracket secures the blower motor inside the housing, keeping the assembly aligned and vibration-free for quiet, efficient airflow. A cracked, corroded, or fatigued mount arm causes motor wobble, rattling, and premature bearing wear — replacing it with the exact OEM part restores factory tolerances.
The OEM B1376853 matches the original mounting-hole pattern and gauge thickness exactly, so it bolts in without modification and maintains the manufacturer's vibration spec. Generic or universal mount arms may require drilling, shimming, or bending, and rarely meet OEM rigidity standards — risking noise and motor stress. For a furnace blower assembly, OEM fit is the safe choice.
Easy to Moderate — Disconnect power, slide out the blower assembly, transfer the motor to the new mount arm, and reinstall. Basic hand tools required; budget 20–40 minutes. If you are not comfortable working inside the blower compartment, consult a licensed HVAC technician.
