The Goodman B1376853 Motor Mount Arm is a genuine OEM bracket that secures the blower motor inside the Goodman AEPF426016BA air handler. These mount arms attach the motor's belly-band to the blower housing, holding the motor concentric to the wheel and absorbing operating vibration. A bent, corroded, or broken mount arm lets the motor sag or shift, which throws the blower wheel out of alignment and causes noise, rubbing, and accelerated bearing wear.
This genuine Goodman OEM arm matches the factory bolt pattern, arm length, and bend angle so the motor sits at the correct depth and the wheel clears the housing. Generic or improvised brackets rarely match the geometry exactly, and even small offsets cause the wheel to rub or the motor to run off-center. At this price, OEM is the obvious choice.
Easy to Moderate. Once the motor is accessible, the arm bolts to the belly-band and housing with standard fasteners — 10–20 minutes per arm. The work is straightforward, but reaching the motor may require pulling the blower assembly. Disconnect power before servicing and re-check motor alignment after tightening.
