The Goodman B1376853 is a genuine OEM motor mount arm that secures the condenser fan motor to the top grille assembly of APH1442H41DA heat pump units. These support arms hold the motor in precise alignment so the fan blade spins true and clears the shroud. Over years of vibration and weather exposure, mount arms can crack, rust, or fatigue — a worn arm causes fan wobble, noise, and premature motor bearing wear.
The OEM mount arm matches the original bolt pattern and length exactly, ensuring proper motor centering with no rebalancing. Generic universal brackets exist but may require drilling or shimming; the OEM part is the drop-in choice.
Rating: Easy. A basic bolt-on repair. Disconnect power, remove the fan grille, swap the arm, and reinstall. No refrigerant work required — suitable for a confident DIYer, though motor alignment should be double-checked.
