The Goodman B1376863 Motor Mount is a genuine OEM bracket (belly-band style support) that secures the blower motor inside the ACEC801005CXAA and other compatible Goodman/Amana furnaces and air handlers. The mount cradles the motor in the blower housing and isolates vibration, keeping the wheel concentric and quiet. A cracked, rusted, or bent mount lets the motor shift, causing noise, wheel rub, and premature bearing wear.
The OEM B1376863 matches the blower housing's exact bolt pattern and the motor's diameter, so the wheel stays centered and balanced. Generic or universal mounts often require drilling new holes and can leave the motor slightly off-axis, leading to vibration and noise. The OEM bracket bolts up with no fabrication.
Moderate. Accessing the blower usually means pulling the blower assembly from the furnace, transferring the motor and wheel to the new mount, and re-torquing the set screw. With power off, this is achievable for an experienced DIYer, but confirm the wheel spins freely and is centered before reinstalling. Many owners prefer a technician for blower work.
