The Goodman B1376853 Motor Mount Arm is the genuine OEM bracket that supports the condenser fan motor inside the APH1448H41EB heat pump. This stamped-steel arm holds the fan motor rigidly over the coil, maintaining correct blade-to-shroud clearance and eliminating the vibration and noise that develop when a mount cracks, rusts through, or fatigues with age.
Because this bracket is a factory OEM part, its bolt hole pattern and offset match your unit exactly, so the motor sits at the correct height and the fan blade tracks true. Universal aftermarket mounts often require drilling new holes or shimming, which can throw off blade clearance and shorten motor bearing life. For a few dollars, OEM is the right call.
With power disconnected at the breaker, remove the fan grille, transfer the motor to the new arm using the original hardware, and reinstall — typically a 20–30 minute job with basic hand tools. No refrigerant work is involved. Confirm blade clearance before restoring power. This low-cost part is often replaced proactively alongside a fan motor swap.
