The Goodman B1376853 Motor Mount Arm is a genuine OEM structural component that supports the blower motor in the Goodman ADPF18241BA air handler and compatible units. The mount arm bridges the motor mount band to the blower housing, holding the motor centered within the blower wheel. Working with the mount band (B1376851), these arms keep the motor rigidly positioned to minimize vibration and maintain proper wheel clearance. A bent or broken arm causes motor sag, wheel contact, noise, and accelerated wear.
Genuine Goodman arms match the factory bolt pattern, length, and bend geometry so the motor sits at the correct depth and angle. Generic or bent-to-fit alternatives risk misalignment, blower wheel rub, and uneven loading on the motor bearings. OEM is recommended for a precise, lasting fit.
Easy to Intermediate (DIY-friendly). No refrigerant handling needed. Disconnect power, support the motor, swap the arm at the housing and band mounting points, and re-center the assembly. Basic hand tools required. Estimated time: 20–40 minutes.
