Goodman B1376857 Blower Motor Mount Arm

The B1376857 is a genuine Goodman blower motor mounting arm engineered for the ACVM970603BNAA modulating variable-speed gas furnace. This belly-band style mount arm secures the ECM blower motor inside the housing, maintaining proper alignment so the blower wheel spins true and vibration-free. A bent, corroded, or fatigued mount arm is a common cause of blower rattle, wheel rub, and premature bearing wear — replacing it restores quiet, balanced airflow.

OEM vs. Generic

This is a factory OEM Goodman component — the bolt pattern, arm length, and motor-band radius match your furnace exactly. Generic or universal mount kits often require drilling, shimming, or re-bending and can leave the motor off-center. The OEM arm drops in with no fabrication.

Installation Difficulty

Moderate (2/5). Requires disconnecting power, removing the blower assembly, and transferring the motor to the new arm. Most DIYers with basic hand tools complete it in 30–45 minutes. Always shut off power at the disconnect before servicing.
