{"product_id":"oem-lennox-pressure-switch-w-bracket-24w97","title":"OEM Lennox Pressure Switch w\/ Bracket — 24W97","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e24W97\u003c\/strong\u003e pressure switch ships complete with its mounting bracket, giving you a ready-to-install assembly that verifies proper draft before your furnace ignites. It senses the vacuum produced by the draft inducer and only closes its contacts when venting is confirmed safe — a required step in the ignition sequence that guards against flue gas spillage.\u003c\/p\u003e\u003cp\u003eA bad pressure switch usually stops the furnace from lighting entirely. Watch for the inducer motor spinning up with no burner ignition, repeated hard lockouts, or a pressure-switch fault code on the control board. A torn diaphragm, blocked pressure tubing, or a stuck-open switch are the usual culprits.\u003c\/p\u003e\u003cp\u003eOEM matters because the \u003cstrong\u003e24W97\u003c\/strong\u003e is calibrated to the precise pressure set point specified for your Lennox furnace and comes with the correct bracket geometry for proper positioning against the inducer housing. Generic switches with the wrong set point or mounting can cause nuisance faults or, worse, allow unsafe firing. This factory assembly restores safe, reliable operation with an exact fit.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081111978355,"sku":"LNX-24W97","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-24W97.jpg?v=1783762942","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-pressure-switch-w-bracket-24w97","provider":"National HVAC Parts","version":"1.0","type":"link"}
