Carrier LA660003 Draft Inducer Fan W/Retaining Ring

The Carrier LA660003 Draft Inducer Fan W/Retaining Ring regulates combustion airflow by managing exhaust gas movement through the venting system during heating operations. It is positioned within the furnace blower and flue assembly and interfaces with the combustion chamber outlet and vent pipe connections through aligned mounting points. The component is configured with a fan impeller structure and retaining ring support that maintains stable rotational alignment and air flow direction. It regulates draft pressure during ignition and heating cycles, maintaining coordinated exhaust flow across temperature regulation transitions. The assembly supports controlled combustion ventilation and balanced system performance across operation cycles.
