The Goodman B1376853 Motor Mount Arm is a genuine OEM bracket that secures the condenser fan motor inside the APH1648H41AA heat pump. The mount arm bolts to the top grille assembly and cradles the fan motor, keeping it centered and vibration-free while the blade spins. A cracked, corroded, or bent mount arm lets the motor sag or wobble, causing blade strikes, bearing wear, and excessive noise — so replacing a damaged arm restores quiet, balanced airflow.
OEM vs. Generic: The factory OEM arm matches the exact bolt pattern, arm length, and offset for the APH1648H41AA fan deck. Generic or fabricated brackets often mismatch the mounting holes or motor offset, which throws off blade clearance. OEM guarantees a true drop-in fit and proper blade-to-shroud spacing.
Installation Difficulty: Easy. With power disconnected, remove the fan grille/motor assembly, transfer the fan motor to the new arm, and reinstall. Basic hand tools and 20–30 minutes are all that is typically required. Always confirm blade clearance before restoring power.
