OEM Lennox Condenser Fan Motor — Y4635

The genuine OEM Lennox Y4635 condenser fan motor turns the outdoor fan that draws air across the condenser coil, dissipating heat from the refrigerant so your Lennox air conditioner or heat pump can cool effectively. It is built to the precise voltage, RPM, rotation, and mounting specs of the original, delivering the exact airflow your Lennox condenser requires.

Common failure symptoms: a fan that refuses to start or only hums, a motor that overheats and cuts off on thermal overload, grinding or squealing from failing bearings, or a system that runs but delivers little cooling. A weak condenser fan motor raises head pressure, increases energy use, and can lead to compressor damage.

OEM matters for Lennox equipment because generic replacements often differ in shaft size, horsepower, capacitor rating, and rotation direction — mismatches that cause poor cooling and premature failure. The Y4635 is a direct factory replacement that fits and runs exactly like the original, protecting your compressor and restoring full efficiency.
