The B1376857 is a genuine OEM condenser fan motor mount arm engineered for Goodman APH1536M41CA package heat pump systems. This steel bracket arm secures the fan motor to the top pan/orifice assembly, holding the motor and fan blade in precise alignment for balanced airflow and vibration-free operation. A cracked, corroded, or bent mount arm is a common cause of fan wobble, rubbing, and premature motor bearing wear — replacing it with the correct OEM part restores factory geometry.
OEM B1376857 is stamped and drilled to Goodman's exact mounting-hole pattern and arm length, so the motor sits at the correct height and pitch. Universal or fabricated brackets frequently miss the bolt spacing, forcing the motor off-center and throwing the fan blade out of balance. For a factory-correct repair, OEM is the safe choice.
Easy (1/5). Disconnect power, remove the fan top assembly, transfer the motor to the new arm, and reinstall. Basic hand tools and 20–30 minutes. Always confirm blade clearance before restoring power.
All electrical repairs on heat pump equipment should be performed by a qualified HVAC technician.
