The Goodman B1376853 Motor Mount Arm is a genuine OEM support component for the blower motor in the Goodman ASPF303616BA air handler. This arm braces the blower motor within the housing, holding it concentric to the blower wheel and absorbing operating vibration. A bent, cracked, or worn mount arm allows the motor to shift, causing noise, wheel rub, bearing wear, and reduced airflow — replacing it with the exact OEM part restores quiet, balanced operation.
This genuine Goodman OEM arm is formed to match the factory motor bolt circle and housing geometry exactly. Generic arms can throw the motor off-center, leading to wheel contact and premature bearing failure. OEM ensures correct alignment the first time.
Moderate — requires removing the blower assembly and motor. Disconnect power first, then transfer the motor to the new arm and re-seat the assembly. Typically a 45–60 minute job for a competent installer.
