OEM Lennox Blower Motor — 49A45

The genuine OEM Lennox 49A45 is a blower motor that powers airflow through your Lennox furnace or air handler, pushing heated or cooled air out to every register in your home. Reliable blower operation is essential for maintaining designed CFM, protecting the heat exchanger from overheating, and delivering consistent comfort throughout the season.

When a blower motor starts to fail, common warning signs include weak airflow at the vents, loud humming, squealing, or grinding from worn bearings, a motor that overheats and shuts down on thermal overload, intermittent operation, or a blower that won't run at all. Ignoring these symptoms can lead to limit trips, short cycling, and additional strain on other furnace components.

Installing an OEM Lennox motor matters because the 49A45 is built to the exact horsepower, RPM, rotation, and mounting specifications your system requires. A factory-correct part ensures proper airflow, quiet operation, and full compatibility with your Lennox unit — avoiding the fit and performance issues that come with generic replacements. Choose genuine to keep your Lennox equipment running as designed.
