It monitors the negative pressure generated by the inducer draft motor and closes its contacts only once adequate venting is proven, telling the control board it is safe to begin the ignition sequence. This protects your furnace and home from operating with a blocked vent or inadequate draft.\u003c\/p\u003e\u003cp\u003eA failing \u003cstrong\u003e26W41\u003c\/strong\u003e typically causes a furnace that won't fire despite the inducer running, ignition that lights briefly and then drops out, short cycling, or a recurring pressure-switch error code. Torn pressure tubing, a clogged condensate trap, or worn contacts that no longer close on a valid draft are the usual causes.\u003c\/p\u003e\u003cp\u003eChoosing the OEM Lennox \u003cstrong\u003e26W41\u003c\/strong\u003e matters because it is factory-calibrated to the exact pressure threshold your Lennox model requires. A generic replacement with the wrong set point can trigger nuisance lockouts or bypass critical safety protection. The correct factory part guarantees a precise fit, the right trip pressure, and dependable, safe heating performance.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081111159155,"sku":"LNX-26W41","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-single-LNX-26W41.jpg?v=1783763012","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-pressure-switch-26w41","provider":"National HVAC Parts","version":"1.0","type":"link"}
