The Goodman B1376853 Motor Mount Arm is a genuine OEM support component for the blower motor assembly in the Goodman ASPF303616AA air handler. This arm holds the blower motor in its factory position, distributing load and dampening vibration so the motor runs quietly and stays aligned with the blower wheel.
Built to original Goodman specifications, the B1376853 matches the factory bolt pattern and arm geometry for a precise, no-modification fit.
A motor mount arm carries the weight of a spinning motor, so geometry and gauge matter. The OEM Goodman arm guarantees correct bolt spacing and rigidity to prevent motor sag and wheel rub. Generic arms may flex or misalign, leading to noise and premature bearing wear. OEM is recommended for any load-bearing motor support.
Moderate (3/5). Requires removing the blower assembly to access the mount. Best handled by an HVAC technician. Disconnect power before servicing.
