The Goodman B1376853 Motor Mount Arm is a genuine OEM bracket that supports and positions the blower motor in the Goodman ASPF313716AA air handler. The mount arm holds the motor in correct alignment with the blower wheel and housing while dampening vibration and noise during operation. A bent or broken arm can cause wobble, rubbing, bearing wear, and excessive noise.
OEM mount arms are formed to the exact geometry of the ASPF313716AA blower assembly, so the motor sits at the correct depth and angle for proper wheel clearance. Generic arms can throw off alignment, leading to airflow loss and premature motor wear. OEM keeps the blower balanced and quiet.
Rating: Moderate. Replacement requires removing the blower assembly to access the motor and mount, then transferring the motor onto the new arm with correct orientation and clearance. Plan 45–60 minutes. An HVAC technician is recommended to verify wheel balance afterward.
Disconnect power at the breaker before service. Verify your model reads ASPF313716AA before ordering.
