This ignitor glows to a high temperature on each heating cycle to ignite the gas burners in your Lennox furnace, making it essential to reliable heat. It also matches Armstrong part #44744-2 for cross-brand compatibility.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e the furnace clicks and tries to fire but never ignites, cold air blows from the vents, the system locks out after several failed ignition attempts, the ignitor no longer glows, or you spot cracks and discoloration in the silicon carbide element.\u003c\/p\u003e\u003cp\u003eSilicon carbide ignitors are brittle wear items that degrade a little with every thermal cycle, so replacement is a normal part of furnace upkeep. Installing the OEM Lennox \u003cstrong\u003e64X09\u003c\/strong\u003e ensures the correct glow temperature, resistance value, and connector fit for your equipment — universal ignitors often mismatch the control board's timing and fail early. Restore safe, consistent ignition with a true factory-spec part.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081132130675,"sku":"LNX-64X09","price":29.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-igniter-silicon-carbide-LNX-64X09.jpg?v=1783763530","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-silicon-carbide-hot-surface-ignitor-6-125-64x09","provider":"National HVAC Parts","version":"1.0","type":"link"}
