OEM Lennox Fan Motor — Y4176

The genuine OEM Lennox Y4176 fan motor turns the fan blade that moves air across your coil, a job that's essential to both cooling and heating output. Manufactured to Lennox factory specifications, it provides the exact horsepower, RPM, voltage, and rotation direction your unit needs — delivering correct airflow, rated efficiency, and smooth, quiet running.

Fan motors give warning signs before they quit. Common symptoms include a motor that hums but won't spin up, slow or seized blades, loud squealing or grinding from failing bearings, intermittent shut-offs from overheating, or a burnt electrical smell. When the motor fails completely, airflow stops and the compressor can overheat and trip on its high-limit safety.

Why OEM matters: generic replacements often match nameplate specs on paper but miss the exact bearing tolerances, shaft size, and thermal ratings Lennox designed around. An out-of-spec motor can overload the capacitor, cut airflow, and stress nearby parts. Choosing the factory Y4176 ensures a correct fit, preserves your warranty coverage, and keeps your Lennox system operating exactly as engineered.
