The Goodman B1376853 Motor Mount Arm is a genuine OEM mounting bracket for the blower motor used in the ADPF304216CA air handler and compatible Goodman/Amana systems. This arm secures the blower motor to the housing and keeps it correctly aligned with the blower wheel. A bent, cracked, or corroded mount arm allows the motor to shift, causing vibration, noise, and accelerated bearing wear. Replacing it restores a rigid, vibration-free mount.
OEM vs. Generic: The genuine Goodman arm matches the original bolt pattern, length, and bend angle so the motor sits at the correct depth and height. Generic or universal brackets often require drilling or shimming and can leave the motor misaligned. For a structural part that controls alignment, OEM is the smart choice.
Installation Difficulty: Moderate (2/5). With power off at the breaker, support the motor, transfer it to the new arm using the existing band/bolts, and reinstall in the housing. Basic hand tools required. We recommend a qualified technician and always advise verifying your model number before ordering.
