The Goodman B1376857 Motor Mount Arm is a genuine OEM bracket that secures the condenser fan motor to the top panel of the APH1560M41AD packaged heat pump. This stamped-steel arm holds the motor in precise alignment with the fan blade and orifice so the fan runs true, quiet, and vibration-free. Over years of outdoor exposure, mount arms can corrode, crack, or fatigue — replacing a worn arm restores proper motor support and prevents blade strikes.
OEM mount arms match the factory bolt pattern, arm length, and offset exactly, so the motor sits at the correct height and blade clearance. Generic or fabricated arms frequently miss the hole spacing, forcing shims or drilling that can leave the motor misaligned and noisy. At this price point, the genuine part is the clear choice.
Easy to Moderate. With power disconnected, remove the fan grille, unbolt the motor from the old arm, transfer it to the new arm, and reinstall. Basic hand tools only. Take care to preserve the original blade-to-orifice depth.
