The Goodman B1376853 Motor Mount Arm is a genuine OEM support component for AEPF303616BA air handler blower assemblies. This mount arm cradles the blower motor in its correct position, isolating vibration and keeping the motor shaft properly aligned with the blower wheel. A bent, broken, or fatigued mount arm causes noise, wobble, and accelerated bearing wear — this factory replacement restores quiet, stable operation.
The OEM B1376853 reproduces the exact arm length, bend angle, and mounting holes so the motor sits at the correct depth and alignment within the housing. Generic arms may not position the motor accurately, causing wheel rub, imbalance, and added noise.
Difficulty: Easy. Typically replaced as part of a motor mount belly-band set — unbolt the old arm, position the new one, and torque the fasteners. Estimated time: 15–20 minutes. De-energize the unit before service.
