Using flame-rectification, the sensor's metal rod detects the microamp current that flows through an active flame and signals the control board to keep the gas valve open. Without a valid flame signal, the furnace safely shuts off the gas to prevent unburned fuel from accumulating.\u003c\/p\u003e\u003cp\u003eA dirty or worn flame sensor is one of the most frequent causes of intermittent furnace operation. Typical symptoms include burners that ignite and then extinguish after a few seconds, short-cycling, and repeated ignition lockouts — often caused by oxidation buildup on the sensor rod that weakens the flame signal.\u003c\/p\u003e\u003cp\u003eThe OEM \u003cstrong\u003e64K60\u003c\/strong\u003e is manufactured to the precise rod length, material, and mounting Lennox specifies, ensuring a strong, reliable flame signal. Aftermarket sensors often position the rod incorrectly in the flame or degrade quickly, leading to recurring nuisance shutdowns. This factory replacement restores dependable, safe burner operation.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081088876915,"sku":"LNX-64K60","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-flame-sensor-straight-LNX-64K60.jpg?v=1783761036","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-flame-sensor-64k60","provider":"National HVAC Parts","version":"1.0","type":"link"}
