The Goodman B1376857 is a genuine OEM fan motor mount arm for the APH1636M41AA heat pump. This mounting bracket supports the condenser fan motor within the top grille assembly, holding it in precise alignment so the fan blade clears the shroud and spins without vibration. A bent or corroded mount arm causes wobble, noise, and premature motor bearing wear — this exact-fit replacement restores solid, quiet support.
Mount arms are model-specific: hole spacing, arm length, and offset all determine whether the motor sits at the correct height and the blade clears the housing. This OEM bracket bolts to the original mounting points with no drilling or modification, while generic arms frequently require field bending to fit. The factory part guarantees correct geometry the first time.
A straightforward mechanical repair. Disconnect power at the breaker, remove the top grille and fan assembly, transfer the motor to the new arm using the existing hardware, and reinstall. No refrigerant or electrical rewiring is required. Most homeowners comfortable with basic hand tools can complete this in under an hour.
Genuine Goodman hardware for a secure, rattle-free fit.
