{"product_id":"oem-lennox-flame-sensor-96m48","title":"OEM Lennox Flame Sensor — 96M48","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e96M48\u003c\/strong\u003e flame sensor is a precision safety component that confirms the presence of a flame after your gas furnace ignites. Using flame rectification, the sensor sends a small microamp signal to the control board verifying combustion; if no flame is detected, the board shuts off the gas valve to prevent unburned fuel from accumulating.\u003c\/p\u003e\u003cp\u003eA dirty, corroded, or failing flame sensor is a leading cause of furnace short-cycling. Typical symptoms include a furnace that lights briefly then shuts off within a few seconds, repeated ignition attempts, or a system that locks out and blows cold air. Over time, oxidation on the sensor rod weakens the signal until the board can no longer confirm the flame.\u003c\/p\u003e\u003cp\u003eInstalling the OEM Lennox \u003cstrong\u003e96M48\u003c\/strong\u003e ensures the correct rod length, material, and mounting for a strong, stable flame signal. Off-brand sensors can produce weak or erratic readings that trigger nuisance shutdowns. Restore safe, uninterrupted heating with the factory-specified flame sensor.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081090974067,"sku":"LNX-96M48","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-96M48.jpg?v=1783761043","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-flame-sensor-96m48","provider":"National HVAC Parts","version":"1.0","type":"link"}
