{"product_id":"oem-lennox-high-pressure-switch-93w01","title":"OEM Lennox High Pressure Switch — 93W01","description":"\u003cp\u003eThe genuine OEM Lennox \u003cstrong\u003e93W01\u003c\/strong\u003e high pressure switch is a factory-calibrated safety device that protects your Lennox system's compressor from excessive discharge pressure. Mounted on the high-side refrigerant line, it monitors pressure continuously and opens the control circuit to stop the compressor the moment pressure exceeds safe limits — a condition typically triggered by a clogged condenser, a stalled condenser fan motor, refrigerant overcharge, or blocked airflow.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCommon failure symptoms:\u003c\/strong\u003e When the \u003cstrong\u003e93W01\u003c\/strong\u003e fails, expect recurring high-pressure trips, a compressor that cuts out mid-cycle, hard-start or no-start conditions, or an intermittent loss of cooling. A switch stuck open will keep the system from running, while one stuck closed silently removes vital overpressure protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy OEM matters:\u003c\/strong\u003e The \u003cstrong\u003e93W01\u003c\/strong\u003e is engineered to Lennox's precise trip and reset specifications so it protects the compressor without causing false shutdowns. Universal aftermarket switches often carry mismatched setpoints and connectors that compromise safety and reliability. The authentic OEM part restores your Lennox unit to factory protection standards.\u003c\/p\u003e","brand":"Lennox","offers":[{"title":"Default Title","offer_id":63081140552051,"sku":"LNX-93W01","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-93W01.jpg?v=1783761996","url":"https:\/\/nationalhvacparts.com\/products\/oem-lennox-high-pressure-switch-93w01","provider":"National HVAC Parts","version":"1.0","type":"link"}
