This flame-rectification sensor confirms the presence of a stable burner flame and signals the control board to keep the gas valve open — a critical safety function that shuts the boiler down if flame is lost, preventing raw gas from accumulating.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e the boiler ignites and then locks out after a few seconds, intermittent flame-failure fault codes, repeated ignition retries, or a unit that won't stay lit. A carbon-coated, corroded, or cracked sensor rod loses its ability to conduct the microamp flame signal and triggers these nuisance shutdowns.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e flame sensing depends on precise rod length, ceramic insulator integrity, and correct positioning within the flame envelope. The OEM \u003cstrong\u003eY5352\u003c\/strong\u003e is built to Lennox specifications so the flame current stays within the control's detection window, ensuring reliable ignition and code-compliant safe operation of your condensing boiler.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081078423923,"sku":"LNX-Y5352","price":19.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-flame-sensor-kit-y5352-dkvlt-050-075-100","provider":"National HVAC Parts","version":"1.0","type":"link"}
