The Goodman B1376863 is a genuine OEM blower motor mount bracket engineered for the ACES800804BXAA gas furnace and compatible Goodman/Amana air handlers. This mounting band secures the blower motor inside the housing, holding it concentric to the blower wheel so the assembly runs true, quiet, and vibration-free. A worn, cracked, or corroded mount lets the motor sag, which causes wheel rub, bearing wear, and rattling at startup.
OEM vs. Generic: This is the factory Goodman part, dimensionally matched to the original motor diameter and housing bolt pattern. Generic universal mounts exist but often require drilling new holes and bending tabs to fit, which can throw off motor alignment. The OEM B1376863 drops straight in with no modification, protecting your blower wheel and motor warranty.
Install difficulty: Moderate (2/5). A DIY-friendly job for a confident homeowner — disconnect power at the breaker, remove the blower assembly, transfer the motor to the new mount, and reinstall. Most installations take 30–45 minutes with basic hand tools. Always cut power before servicing and verify the motor shaft is centered in the wheel before restoring power.
