The B1376857 is a genuine OEM condenser fan motor mount arm engineered for the Goodman/Amana APH1424M41AA packaged heat pump. This stamped-steel support arm secures the condenser fan motor to the top grille assembly, holding the motor and blade in precise alignment so the fan clears the shroud and runs vibration-free. A cracked, corroded, or bent mount arm is one of the most common causes of fan wobble, rubbing, and premature motor bearing failure — replacing it with the correct OEM part restores factory geometry.
This is the OEM Goodman arm, laser-matched to the factory mounting-hole pattern and motor stud spacing. Generic universal brackets require drilling and shimming to fit and rarely reproduce the exact standoff height, which can throw off blade-to-shroud clearance. For a drop-in repair, the OEM part is the safe choice.
Moderate. Requires disconnecting power, removing the top fan grille, transferring the motor and blade to the new arm, and re-torquing the fasteners. No refrigerant work or EPA certification needed. Typical DIY time: 45–60 minutes.
