{"product_id":"oem-lennox-high-pressure-switch-13r26","title":"OEM Lennox High Pressure Switch — 13R26","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e13R26\u003c\/strong\u003e high pressure switch is a critical safety control that monitors refrigerant discharge pressure in your Lennox air conditioner or heat pump. When system pressure climbs past its factory-calibrated trip point, the switch opens the control circuit and shuts down the compressor before dangerous pressures can cause damage.\u003c\/p\u003e\u003cp\u003eCommon symptoms of a bad high pressure switch include a compressor that trips off on hot days, nuisance lockouts, no cooling, or a unit that repeatedly cycles and displays a high-pressure fault code. A switch stuck open prevents the system from running at all, while one that won't trip removes vital compressor protection.\u003c\/p\u003e\u003cp\u003eOEM matters here because the \u003cstrong\u003e13R26\u003c\/strong\u003e is calibrated to the exact cut-out and reset pressures Lennox engineered for this equipment. An aftermarket switch with the wrong setpoints can allow compressor-damaging pressures or cause constant false trips. This factory-spec replacement restores accurate protection and reliable, safe operation.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081133474163,"sku":"LNX-13R26","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-13R26.jpg?v=1783761979","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-high-pressure-switch-13r26","provider":"National HVAC Parts","version":"1.0","type":"link"}
