{"product_id":"oem-lennox-blower-wheel-21706","title":"OEM Lennox Blower Wheel — 21706","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e21706\u003c\/strong\u003e blower wheel is the rotating squirrel-cage component that moves conditioned air through your furnace or air handler and out into the ductwork. Precision-balanced from the factory, it delivers the rated airflow (CFM) your Lennox system was engineered around, keeping heating and cooling even from room to room while running quietly.\u003c\/p\u003e\u003cp\u003eWhen a blower wheel fails or fouls, the symptoms are hard to miss: weak airflow at the registers, a noticeable drop in heating or cooling performance, rattling, scraping, or vibration noises, and short-cycling caused by overheating or a tripped limit switch. Bent fins, cracked hubs, a loose set screw, or a heavy buildup of dust and debris all throw the wheel out of balance and strain the blower motor.\u003c\/p\u003e\u003cp\u003eChoosing the OEM \u003cstrong\u003e21706\u003c\/strong\u003e matters because Lennox blower wheels are matched to a specific motor, housing, and blade geometry. An aftermarket wheel with the wrong diameter, width, or rotation can under- or over-load the motor, kill efficiency, and shorten motor life. This factory replacement drops in for a correct fit, restored airflow, and balanced, long-lasting operation.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081116991859,"sku":"LNX-21706","price":89.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-blower-wheel-LNX-21706.jpg?v=1783759470","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-blower-wheel-21706","provider":"National HVAC Parts","version":"1.0","type":"link"}
