OEM Lennox Power Exhaust Fan Motor — 36W65

The genuine OEM Lennox 36W65 power exhaust fan motor drives the exhaust blower used to relieve building pressure and expel stale or return air on Lennox rooftop and packaged units. By moving air out of the space as the economizer or ventilation system brings fresh air in, this motor keeps building pressure balanced and airflow correct. It is manufactured to Lennox factory specifications for voltage, speed, and mounting for a direct, hassle-free replacement.

Common symptoms of a failing power exhaust motor include an exhaust fan that won't start or runs erratically, humming without rotation, grinding or squealing bearings, tripped overloads, or building pressure problems such as doors that are hard to open or whistling around openings. A motor that overheats and cycles off is another clear sign of wear.

Using an OEM Lennox 36W65 guarantees the correct electrical characteristics and physical fit that your unit's control and ventilation sequence depend on. Generic motors risk improper amp draw, poor sealing, and premature failure that can disrupt building pressurization. This part is in stock and ships same day so your ventilation system is back online quickly.
