The hot surface ignitor glows and ignites the gas, while the integrated flame sensor generates a small microamp signal that tells the control board the burners lit successfully. Without a valid flame signal, the board shuts the gas valve to keep your home safe. This genuine OEM assembly is a direct fit for compatible Lennox furnaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms\u003c\/strong\u003e include a furnace that clicks but never ignites, burners that light and then go out after a few seconds (a false flame-sense reading), repeated ignition lockouts, no heat on call, and a visibly cracked or worn ignitor element. Flame sensors also fail when the rod becomes coated with oxidation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Ignition timing and flame-sense sensitivity are tuned to your specific Lennox control board. A genuine \u003cstrong\u003e62K50\u003c\/strong\u003e ensures the ignitor reaches the correct temperature on schedule and the flame sensor produces the microamp reading the board expects — eliminating the nuisance lockouts and short-cycling common with generic parts. Installing the OEM assembly restores dependable, safe ignition exactly as Lennox engineered it.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081099493747,"sku":"LNX-62K50","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-62K50.jpg?v=1783762140","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-ignitor-flame-sensor-assembly-62k50","provider":"National HVAC Parts","version":"1.0","type":"link"}
