{"product_id":"oem-lennox-pressure-switch-84m96","title":"OEM Lennox Pressure Switch — 84M96","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e84M96\u003c\/strong\u003e pressure switch is a precision safety control that monitors refrigerant pressure in your Lennox HVAC system and interrupts compressor operation whenever pressure drifts outside safe limits. By responding to abnormal pressure conditions — caused by refrigerant loss, restricted airflow, or condenser issues — it shields the compressor and other costly components from avoidable damage. The switch is factory-set to the exact thresholds your Lennox equipment requires.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e A worn or failed \u003cstrong\u003e84M96\u003c\/strong\u003e can lead to short-cycling, nuisance lockouts, a compressor that refuses to start, or a system tripping on a pressure fault. A stuck-open switch prevents the unit from operating, while a stuck-closed switch leaves the compressor without essential protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e Generic replacement switches often rely on approximate pressure setpoints that don't match Lennox's engineering, resulting in false trips or insufficient protection. The authentic OEM \u003cstrong\u003e84M96\u003c\/strong\u003e delivers the correct calibration, connector fit, and proven durability — restoring safe, reliable performance to your Lennox system the first time.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081140584819,"sku":"LNX-84M96","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-84M96.jpg?v=1783763093","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-pressure-switch-84m96","provider":"National HVAC Parts","version":"1.0","type":"link"}
