The Goodman 0271A00013S Blower Housing is a genuine OEM replacement scroll housing engineered specifically for the ATUF374316AA air handler and compatible Goodman/Amana models. The blower housing surrounds the squirrel-cage wheel and directs conditioned air into the duct system. A cracked, corroded, or rattling housing causes air leakage, whistling, and reduced static performance — replacing it with the factory part restores rated CFM and quiet operation.
This is a true OEM Goodman component, machined to the original cutoff plate and inlet ring dimensions so the blower wheel clearance and airflow path match factory spec exactly. Aftermarket generic housings often deviate on bolt patterns and inlet diameter, leading to wheel rub, vibration, and lost efficiency. For a balanced, drop-in fit, OEM is the safe choice.
Moderate. Requires removing the blower assembly, transferring the motor and wheel, and re-seating the housing. Plan 45–90 minutes with basic hand tools. Always disconnect power before servicing. If you're not comfortable pulling the blower deck, a licensed HVAC technician can complete the swap quickly.
