The genuine OEM Lennox 11K98 induced draft motor upgrade kit provides everything needed to replace the draft inducer assembly in compatible Lennox furnaces. The induced draft motor pulls combustion gases through the heat exchanger and safely expels them out the flue, establishing the proper draft that allows the burners to ignite and the pressure switch to close. This upgrade kit includes the updated motor and required hardware for a complete, reliable restoration of your furnace's venting system.

Common failure symptoms: A failing inducer motor covered by the 11K98 kit often produces loud humming, rattling, or grinding noises, slow or no startup, and a furnace that fails to ignite because the pressure switch never closes. Worn bearings and reduced airflow are frequent signs the motor needs replacement.

Why OEM matters: The draft inducer is central to safe combustion and proper venting. The genuine Lennox 11K98 upgrade kit is engineered to deliver the exact airflow, mounting fit, and electrical characteristics your furnace requires — ensuring reliable pressure-switch operation, safe flue draft, and long service life that generic motors cannot guarantee.
