The B1376863 is the genuine OEM blower motor mount assembly engineered for the Goodman ACVC80805CXBD 80% AFUE variable-speed gas furnace. This steel mounting band cradles the blower (ECM/PSC) motor inside the housing, holding it in precise alignment with the blower wheel while isolating motor vibration from the cabinet. A worn, cracked, or rusted mount causes rattling, wheel rub, and premature bearing wear — replacing it restores quiet, balanced airflow.
This genuine OEM mount matches the factory bolt spacing, motor band diameter, and gauge thickness exactly — no shimming or drilling. Generic universal bands are often the wrong diameter or too thin, leading to motor sag and renewed vibration. For a precise, lasting repair on your variable-speed unit, OEM is the safe choice.
Moderate (2/5). Cut power at the breaker, remove the blower assembly, swap the mount band, and reinstall. Basic hand tools; budget 30–45 minutes. If you are not comfortable handling the blower deck, use a licensed HVAC technician.
