The Goodman B1376863 is a genuine OEM blower motor mount designed for the Goodman ACVC801005CXAA gas furnace. This mounting component secures the blower motor within the housing and dampens vibration, ensuring quiet, stable operation. Worn, cracked, or corroded motor mounts allow the motor to shift or vibrate, leading to excessive noise, blower wheel imbalance, and premature motor bearing wear. Replacing the mount restores proper alignment and protects your blower assembly.
Motor mounts are dimension-critical — bolt-hole spacing, ring diameter, and material durometer all affect fit and vibration control. The OEM B1376863 matches the factory blower assembly exactly, so the motor sits square and balanced. Generic or universal mounts often require modification and may not isolate vibration as effectively.
Moderate (3/5). Accessing the mount usually requires removing the blower assembly from the furnace. Plan 45-60 minutes. Disconnect power, slide out the blower, replace mounts (typically replace all in a set for even support), and reinstall.
