The Goodman B1376853 Motor Mount Arm is the genuine OEM mounting bracket that secures the condenser fan motor inside Goodman WPC4442AHAB air conditioning units. This stamped-steel support arm holds the fan motor in correct alignment with the fan blade, preventing wobble, vibration, and premature bearing wear. A bent, corroded, or cracked mount arm is a common cause of noisy operation and fan strikes — replacing it restores smooth, balanced airflow across the condenser coil.
The genuine Goodman OEM mount arm is engineered to the exact bolt pattern and bracket geometry of your unit, guaranteeing proper motor-to-blade clearance. Generic aftermarket brackets often require drilling or shimming and may not hold factory alignment tolerances. For a no-modification, drop-in replacement, the OEM part is the safe choice.
Easy (1/5). Disconnect power, remove the fan grille and motor, transfer the motor to the new arm, and reassemble. Basic hand tools and 20–30 minutes are typically all that is required.
