Pressure switches are safety-sensing components found in gas furnaces and air handlers. They monitor negative pressure created by the inducer motor to confirm proper draft before allowing ignition. The orange color designation indicates a specific setpoint, helping technicians verify the correct switch is installed at a glance. This part is handled primarily by licensed HVAC technicians during routine maintenance or fault diagnosis.\u003c\/p\u003e\u003cp\u003eThis pressure switch is designed for use in HVAC systems where draft-proving or pressure-proving functions are required. It is a direct-fit replacement for failed or out-of-tolerance switches in furnace applications. When a furnace fails to ignite or throws a pressure-switch fault code, this is a common service part. Its compact form factor fits standard furnace control board wiring harnesses and tubing configurations typical of residential and light commercial gas heating equipment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eRated setpoint of 0.7 inches WC for accurate draft or pressure proving\u003c\/li\u003e\n\u003cli\u003eOrange color coding allows fast visual confirmation of correct setpoint\u003c\/li\u003e\n\u003cli\u003eOEM-style replacement designed for HVAC furnace applications\u003c\/li\u003e\n\u003cli\u003eCompact form factor compatible with standard furnace tubing and wiring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement pressure switch for use in HVAC furnace and air handler systems requiring a 0.7 inches WC rated switch.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Always shut off power to the furnace at the disconnect switch and turn off gas supply before replacing a pressure switch. Disconnect the rubber sensing tube and electrical connector carefully, noting routing before removal. Verify the replacement switch setpoint and color code match the original before completing the repair.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Pressure Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetpoint\u003c\/strong\u003e: 0.7 inches WC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Orange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: HVAC System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: LENNOX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 57W82\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"LENNOX","offers":[{"title":"Default Title","offer_id":51284043137330,"sku":"57W82","price":72.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309278773.jpg?v=1781067017","url":"https:\/\/voomisupply.com\/products\/lennox-57w82-pressure-switch-0-7-inches-wc-orange","provider":"Voomi Supply","version":"1.0","type":"link"}
