{"product_id":"oem-lennox-combustion-air-blower-13u29","title":"OEM Lennox Combustion Air Blower — 13U29","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e13U29\u003c\/strong\u003e combustion air blower — also called a draft inducer — pulls fresh combustion air through the heat exchanger and pushes flue gases safely out of your Lennox furnace. This motor creates the negative pressure the pressure switch verifies before the burners fire, making it essential to both efficiency and safe venting.\u003c\/p\u003e\u003cp\u003eSymptoms of a failing inducer include a furnace that won't ignite, a loud humming or grinding noise at startup, rattling bearings, the blower running but not spinning up to speed, or a unit that locks out on a pressure-switch fault. A seized or weak inducer stops the ignition sequence entirely, leaving you without heat.\u003c\/p\u003e\u003cp\u003eChoosing the OEM \u003cstrong\u003e13U29\u003c\/strong\u003e matters because Lennox calibrated this blower's airflow and RPM to work with the furnace's pressure switch and heat exchanger. An incorrect motor can cause venting problems, nuisance lockouts, or unsafe operation. This factory replacement restores proper draft, safe combustion, and reliable heating.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081133572467,"sku":"LNX-13U29","price":89.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-draft-inducer-LNX-13U29.jpg?v=1783759666","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-combustion-air-blower-13u29","provider":"National HVAC Parts","version":"1.0","type":"link"}
