The blower wheel is the heart of the air handler's airflow — a worn, cracked, or out-of-balance wheel causes weak airflow, rattling, and premature motor failure. This factory wheel restores rated CFM and quiet operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Number:\u003c\/strong\u003e D6723311S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheel Size:\u003c\/strong\u003e 11 in diameter x 10 in width\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Forward-curved centrifugal (squirrel cage)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEquipment:\u003c\/strong\u003e Air Handler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Model:\u003c\/strong\u003e WAHMS3743P4ACA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Goodman (genuine OEM)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eOEM vs. Generic\u003c\/h3\u003e\u003cp\u003eThe OEM D6723311S is dynamically balanced and dimensionally matched to the original housing and motor shaft, preventing vibration that destroys bearings. Generic wheels may differ in blade pitch or bore size, reducing airflow and introducing noise. Because the wheel directly loads the blower motor, an out-of-spec replacement shortens motor life — making OEM the cost-effective long-term choice.\u003c\/p\u003e\u003ch3\u003eInstallation Difficulty\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eModerate (3\/5).\u003c\/strong\u003e Requires disconnecting power, removing the blower assembly, loosening the set screw on the motor shaft, and transferring the wheel with correct shaft depth and set-screw seating on the flat.
