It turns the circulating blower on when the heat exchanger warms up and off when it cools, while its integrated high-limit function cuts power to the burners if plenum temperatures climb too high — a key safeguard against heat exchanger damage and overheating.\u003c\/p\u003e\u003cp\u003eWhen the \u003cstrong\u003e13P94\u003c\/strong\u003e control fails, you may experience a blower that won't start or won't shut off, repeated high-limit trips, intermittent no-heat calls, or a furnace that cycles the burners on and off rapidly. Any of these point to a control that is out of calibration or has lost its temperature-sensing accuracy.\u003c\/p\u003e\u003cp\u003eThe OEM \u003cstrong\u003e13P94\u003c\/strong\u003e delivers the precise fan-on, fan-off, and limit trip temperatures specified for Lennox furnaces, along with the correct sensing element and mounting fit. Non-OEM alternatives frequently use approximated setpoints that undermine safe, efficient heating. Fitting the factory-authorized control ensures correct blower timing, dependable safety shutoff, and continued warranty compliance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081114960243,"sku":"LNX-13P94","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-limit-switch-snap-disc-LNX-13P94.jpg?v=1783760741","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-fan-and-limit-control-13p94","provider":"National HVAC Parts","version":"1.0","type":"link"}
