The Goodman 2539306S Blower Housing is a genuine OEM 10 x 8 inch scroll assembly engineered for the GMPE075-3A multi-position gas furnace and compatible Goodman blower systems. The housing cradles the blower wheel and shapes airflow through the heat exchanger, so a cracked, warped, or corroded housing directly reduces CFM output and heating efficiency. This factory replacement restores the exact geometry the furnace was designed around.
The genuine Goodman housing matches original bolt patterns, wheel clearance, and cutoff plate location exactly — no shimming or drilling. Aftermarket housings often differ slightly in scroll radius, which introduces vibration and airflow noise. For a load-bearing airflow component, OEM is the safer choice.
Moderate — requires removing the blower assembly, transferring the motor and wheel, and reconnecting the mount. Budget 45–75 minutes. Always disconnect power before servicing.
