The Goodman B1376853 is a genuine OEM fan motor mount arm engineered for the Goodman/Amana APH1630H41AC heat pump condensing unit. This structural bracket secures the outdoor fan motor to the top grille assembly, holding the motor and blade in precise alignment so the fan spins true and quiet. A cracked, bent, or corroded mount arm is a common cause of fan wobble, vibration noise, and premature bearing wear — replacing it with the exact OEM part restores factory tolerances.
Our OEM B1376853 matches the original bolt-hole pattern, gauge, and coating exactly, so it seats without drilling or bending. Generic universal brackets often require field modification and don't carry the same corrosion protection — for a load-bearing part exposed to weather, the exact-fit OEM arm is the reliable choice.
Difficulty: Easy. A basic nut-driver replacement — disconnect power, remove the fan grille, transfer the motor to the new arm, and reinstall. Most homeowners and technicians complete it in under 20 minutes. Always confirm power is off at the disconnect before servicing.
