The genuine OEM Lennox 48L96 draft inducer motor assembly powers the combustion venting on your Lennox furnace. It pulls air through the heat exchanger and pushes exhaust gases safely out the flue before and during each heating cycle. Its operation is verified by the pressure switch, so a healthy inducer is essential for the furnace to ignite and run at all.
Common signs of a failing inducer motor include loud humming, grinding, or rattling on startup, a furnace that clicks but never lights, repeated pressure-switch lockouts, or a motor that runs slow and overheats. Worn bearings and a failing capacitor are typical culprits.
The OEM 48L96 assembly is matched to your Lennox model's airflow, CFM, and wheel specifications — details generic replacements rarely reproduce correctly. Installing the factory part restores proper draft, keeps pressure-switch timing accurate, and ensures safe, efficient combustion for your Lennox system.
