When temperatures at the sensing location exceed the 225°F threshold, the control interrupts the heating circuit to protect the heat exchanger and surrounding components from damage. Common failure symptoms include furnace lockout, erratic cycling, or the system failing to ignite during normal operation.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081057649011,"sku":"LNX-74W75","price":19.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-control-limit-225f-102135-10-74w75","provider":"National HVAC Parts","version":"1.0","type":"link"}
