The housing surrounds the blower wheel and directs conditioned air into the supply ductwork. A correctly shaped factory scroll is essential for rated airflow (CFM), low operating noise, and proper static pressure across the coil — a cracked or warped housing leaks air, kills efficiency, and can let the blower wheel rub.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 0271A00013S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Blower housing \/ scroll assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Goodman \/ Amana air handlers, model WAHMS3743P4ACA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Houses blower wheel and channels supply airflow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild:\u003c\/strong\u003e OEM-formed sheet metal with factory mounting points\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eAftermarket housings frequently miss the exact cutout geometry and mount locations of the WAHMS series, forcing drilling, shimming, or wheel-clearance compromises that increase noise and reduce CFM.
