Pressure switches are critical safety and control components in heating and cooling systems. They monitor air pressure within the system and send a signal to the control board to allow or interrupt operation. If the pressure falls outside the acceptable range, the switch opens or closes its circuit to protect the equipment from damage or unsafe operation. This helps prevent issues like heat exchanger failures, inducer motor problems, and inefficient combustion in gas furnaces. The SOURCE1 2439714000 is rated at 0.90 inches of water column, which is the specific pressure threshold this switch is calibrated to detect. Installing the correct pressure rating is essential. A switch with the wrong rating can cause a furnace or air handler to lock out unnecessarily or, worse, allow operation under unsafe conditions. HVAC technicians rely on OEM-spec replacement parts like this one to restore proper system function quickly and confidently. This switch is a direct replacement for the York OEM part number S1-02439714000, making it easy to cross-reference during service calls. It fits into the standard pressure switch circuit and connects via typical push-on terminals. Whether you are servicing a residential furnace or a light commercial air handler, having the correct pressure switch on hand reduces diagnostic time and keeps equipment running safely. SOURCE1 parts are built to meet the original equipment specifications set by York, ensuring compatibility and reliable performance in the field.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eRated at 0.90 inches of water column for precise pressure threshold control\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement for York part number S1-02439714000\u003c\/li\u003e\n\u003cli\u003eCompatible with York furnaces and air handlers requiring a standard pressure switch\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eProduct Highlights\u003c\/h4\u003e\u003cp\u003eThe SOURCE1 2439714000 pressure switch is an OEM-spec replacement calibrated to 0.90 inches of water column, designed to protect and control York HVAC equipment with reliable, accurate pressure monitoring.\u003c\/p\u003e\u003ch3\u003eProduct Information\u003c\/h3\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SOURCE1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2439714000\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 0.90 inches of water column\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1 inches\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"YORK","offers":[{"title":"Default Title","offer_id":51121042686258,"sku":"2439714000","price":40.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/304883167.jpg?v=1778043725","url":"https:\/\/voomisupply.com\/products\/source1-2439714000-pressure-switch-0-90-hvac-replacement-s1-02439714000","provider":"Voomi Supply","version":"1.0","type":"link"}
