OEM Lennox Fan Motor — 49W86

The genuine OEM Lennox 49W86 fan motor drives airflow across the coil in your Lennox HVAC system, spinning the fan blade to move air over the condenser or evaporator for proper heat exchange. Built to Lennox factory specifications, it delivers the correct RPM, torque, and electrical draw your unit was engineered around, ensuring quiet, efficient, and reliable operation season after season.

When a fan motor begins to fail, you'll often notice warning signs before it stops completely: a humming or buzzing noise on startup, a fan that turns slowly or not at all, overheating and thermal cutouts that shut the system down, reduced cooling or heating capacity, or a burning smell from worn bearings and windings. A seized motor can also cause the compressor to overheat, making prompt replacement important.

Choosing the OEM 49W86 matters because Lennox systems are calibrated to precise motor characteristics. Generic aftermarket motors can differ in speed, bearing quality, and mounting, leading to poor airflow, premature failure, or strain on other components. This factory-authorized part guarantees an exact fit, rated performance, and preserves the efficiency and reliability of your Lennox equipment.
