This motor drives the fan that moves air across your Lennox system's coil, maintaining the airflow required for proper heat transfer, temperature control, and rated system efficiency. A healthy fan motor is essential to keeping your Lennox equipment cooling or heating at its designed capacity.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e When the \u003cstrong\u003e16F21\u003c\/strong\u003e begins to fail you may hear humming, grinding, or squealing from worn bearings, notice the fan running slowly or not starting at all, or find the motor overheating and tripping on thermal overload. Reduced airflow, warm supply air, high head pressure, and intermittent shutdowns are common signs of a weakening motor.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Lennox specifies motors by horsepower, RPM, rotation, voltage, and bearing type to match the blade and the unit's electrical characteristics. An aftermarket motor with the wrong speed or torque curve can move too little or too much air, overload the run capacitor, and shorten the life of surrounding components. The factory \u003cstrong\u003e16F21\u003c\/strong\u003e guarantees a correct bolt-in fit and the exact performance your Lennox equipment was built around, restoring quiet, reliable airflow.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081114337651,"sku":"LNX-16F21","price":99.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-blower-motor-psc-LNX-16F21.jpg?v=1783760801","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-fan-motor-16f21","provider":"National HVAC Parts","version":"1.0","type":"link"}
