Carrier LA21RB549 Inducer Wheel

Optimize your furnace's draft performance with the Carrier LA21RB549 Inducer Wheel. As a veteran-grade OEM replacement part, this 5 1/4" diameter and 1" width blower wheel is engineered to maintain precise static pressure within the combustion assembly. This specific draft inducer wheel serves as the direct replacement for LA21RB553, ensuring a seamless drop-in fit for technicians servicing Carrier, Bryant, and Payne residential gas furnaces. Built with high-strength steel to withstand the thermal stress of flue gas exhaustion, it utilizes a 1/4" bore and dual set screws for a secure, balanced attachment to the motor shaft. Replacing a warped or corroded furnace inducer fan wheel is critical for resolving pressure switch trip codes and ensuring efficient exhaust venting. This factory-authorized part restores original equipment specifications for airflow and decibel ratings, providing the reliability required for professional HVAC maintenance and repair.
