The Goodman B1376853 is a genuine OEM fan motor mount arm (support bracket) designed as an exact-fit replacement for the APH1424H41DE heat pump condensing unit. This stamped-steel arm is one of the legs that secures the condenser fan motor to the top grille assembly, holding the motor centered and rigid so the fan blade spins true within the shroud.
Because it is a structural part, mount geometry matters. The OEM B1376853 has the correct length, bend angle, and bolt-hole spacing to keep the motor aligned. Generic or bent-to-fit brackets can shift the motor off-axis, causing blade rub, vibration, and bearing wear. OEM ensures the fan assembly stays balanced and quiet.
Rating: Easy. With power disconnected, remove the top grille/fan assembly, swap the damaged arm for the new one using the existing hardware, and reassemble. Typically a 15–30 minute job requiring only basic hand tools. Always disconnect power at the breaker before servicing.
