It continuously senses temperature in the heat-exchanger or burner area and instantly interrupts the circuit if heat climbs past a safe threshold — shutting down the burners to prevent heat-exchanger damage, component failure, and fire risk.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e the furnace short-cycles or won't fire on a heat call, burners ignite then drop out repeatedly, the system trips to a lockout or displays a limit-fault code, or the unit stays cold despite a working igniter and gas supply. A cut-off can also fail from age, nuisance tripping caused by restricted airflow, or a dirty filter.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e this is a safety-critical component with a precise trip temperature and reset rating specified for your Lennox model. A substitute with the wrong setpoint may trip early, fail to trip when needed, or not seat correctly. The OEM Lennox \u003cstrong\u003e98G47\u003c\/strong\u003e guarantees the exact temperature calibration and mounting fit your equipment requires for safe, reliable protection.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081089139059,"sku":"LNX-98G47","price":39.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-limit-switch-snap-disc-LNX-98G47.jpg?v=1783763908","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-thermal-cut-off-limit-switch-98g47","provider":"National HVAC Parts","version":"1.0","type":"link"}
