{"product_id":"oem-lennox-flame-rollout-switch-15m44","title":"OEM Lennox Flame Rollout Switch — 15M44","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e15M44\u003c\/strong\u003e flame rollout switch is a manual-reset safety control mounted near the burner box of your Lennox furnace. It detects flames that escape, or \"roll out,\" from the combustion chamber — a condition caused by blocked venting, a cracked heat exchanger, or a restricted flue — and immediately cuts power to the gas valve to prevent fire and heat damage.\u003c\/p\u003e\u003cp\u003eTypical symptoms include a furnace that locks out and won't restart, no heat after a rollout event, visible scorching near the burners, or a switch that trips soon after ignition. Because a rollout trip signals a genuine combustion problem, the underlying cause — such as a dirty burner, poor draft, or heat-exchanger crack — should always be inspected along with the switch.\u003c\/p\u003e\u003cp\u003eInstalling the OEM Lennox \u003cstrong\u003e15M44\u003c\/strong\u003e ensures the correct trip temperature and mounting fit your specific furnace design. A substitute switch may trip at the wrong point or fail to react, defeating a life-safety function. The factory-specified part restores proper protection, preserves your warranty, and keeps your Lennox furnace operating safely.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081088483699,"sku":"LNX-15M44","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-limit-switch-rollout-LNX-15M44.jpg?v=1783760964","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-flame-rollout-switch-15m44","provider":"National HVAC Parts","version":"1.0","type":"link"}
