{"product_id":"oem-lennox-flame-rollout-switch-31j95","title":"OEM Lennox Flame Rollout Switch — 31J95","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e31J95\u003c\/strong\u003e flame rollout switch is a temperature-sensing safety limit that protects your Lennox furnace from hazardous flame rollout. Positioned near the burner box, it monitors for excessive heat produced when flames escape the intended combustion path — commonly due to restricted venting, a compromised heat exchanger, or inadequate combustion air — and de-energizes the furnace to keep operation safe.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e When the \u003cstrong\u003e31J95\u003c\/strong\u003e opens or fails, the furnace usually stops producing heat, shuts down mid-cycle, or fails to start. A switch tripped by a real fault stays open until the problem is resolved and the switch is reset, whereas a worn or defective switch can cause repeated nuisance lockouts even during normal firing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e This switch must trip at an exact temperature to safeguard your equipment and home. A generic replacement with the wrong rating may not respond correctly, risking either unsafe operation or unnecessary no-heat calls. The factory \u003cstrong\u003e31J95\u003c\/strong\u003e matches Lennox's precise trip temperature and mounting design, delivering reliable protection and preserving your warranty. Choose genuine OEM for every safety-critical component.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081109324147,"sku":"LNX-31J95","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-31J95.jpg?v=1783760969","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-flame-rollout-switch-31j95","provider":"National HVAC Parts","version":"1.0","type":"link"}
