The genuine OEM Lennox 15B98 fan motor drives airflow across your system's coil, keeping refrigerant temperatures and air delivery within Lennox's rated specifications. Engineered to the exact electrical and mechanical tolerances of your original unit, it installs as a true drop-in replacement and preserves the balance, bearing life, and efficiency your Lennox equipment was designed around.

Common failure symptoms: a motor nearing the end of its life often shows up as weak or no airflow, a hum without rotation, overheating and thermal shutdowns, loud bearing noise or wobble, or a unit that trips its breaker on start. Left unaddressed, a failing fan motor can drive up head pressures and shorten compressor life.

Why OEM matters: the Lennox 15B98 is matched to the correct horsepower, RPM, rotation, and mounting for your system. Generic substitutes frequently differ in shaft size, bearing type, or torque curve, leading to poor airflow, premature wear, and voided warranties. Choosing the OEM part protects your equipment and guarantees proper fit and performance. In stock and ships same day.
