By sensing negative pressure in the venting system, it protects against dangerous flue blockages and improper combustion, allowing the control board to proceed only when it's safe to ignite.\u003c\/p\u003e\u003cp\u003eA failing pressure switch commonly shows up as a furnace that ignites briefly and shuts down, repeated lockouts, no ignition at all, or diagnostic flash codes indicating an open or stuck switch. Cracked tubing, condensate blockage, or a worn diaphragm can all prevent the switch from closing properly and halt heating.\u003c\/p\u003e\u003cp\u003eInstalling an OEM Lennox \u003cstrong\u003e97M02\u003c\/strong\u003e ensures the switch is calibrated to the exact pressure setpoint your furnace model requires — a specification generic replacements frequently miss. Because this is a life-safety component, factory-original calibration and construction are essential for reliable, code-compliant operation and to keep your Lennox equipment protected.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081090744691,"sku":"LNX-97M02","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-97M02.jpg?v=1783763103","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-pressure-switch-97m02","provider":"National HVAC Parts","version":"1.0","type":"link"}
