The Goodman B1376857 Motor Mount Arm is a genuine OEM bracket that supports the condenser fan motor in the APH1424M41AC heat pump. This stamped mounting arm bridges the top grille or fan deck to the motor, holding the motor and blade assembly in correct alignment above the condenser coil so the fan pulls air cleanly and vibrates minimally.
The OEM B1376857 is stamped to Goodman's exact hole pattern and arm length, so the fan blade sits at the correct height and clearance within the shroud. Bending a universal bracket to fit risks blade strikes, uneven airflow, and premature motor-bearing wear. This inexpensive OEM part is worth getting right.
Difficulty: Easy. A simple bolt-on replacement with basic hand tools — no refrigerant work. DIY-friendly for a handy owner; about 15–30 minutes.
