The Goodman 2539306S Blower Housing is a genuine OEM 10" x 8" steel blower scroll for Goodman DMS80904BNA and compatible 90,000 BTU gas furnaces. The housing encloses the squirrel-cage blower wheel and shapes airflow through the cabinet, delivering conditioned air to the duct system. A cracked, rusted, or damaged housing causes air leakage, whistling, reduced CFM, and vibration. This factory replacement restores proper static pressure and quiet, efficient air delivery.
This genuine Goodman OEM housing matches the exact scroll geometry, cutoff plate position, and mounting points your furnace requires, preserving rated airflow and blower wheel clearance. Generic housings often differ in wheel bore or mounting flange, causing rubbing, imbalance, or airflow loss. For a component this central to system performance, OEM ensures a true bolt-in fit.
Advanced — professional installation recommended (60–90 min). Requires removing the full blower assembly, transferring the wheel and motor, setting proper wheel-to-cutoff clearance, and re-balancing. Improper wheel spacing causes noise and airflow problems. A licensed HVAC technician should perform this repair and verify blower performance.
