The pressure switch is a critical safety device that confirms proper venting and inducer draft before allowing the igniter and gas valve to operate. If it senses a blocked flue, weak draft, or condensate backup, it blocks ignition to prevent hazardous flue gas spillage. A stuck-open or failed switch triggers lockouts, fault codes, and no-heat conditions. This factory-spec replacement matches the original pressure setpoint, hose connection, and electrical terminals for a true direct fit. Installation is a moderate DIY task of about 15-20 minutes, transferring the rubber tube and two wires after disconnecting power. Using the correct OEM-rated switch matters, because the wrong setpoint defeats an essential safety function. Restore safe, reliable heating with a component built to factory standards rather than a questionable aftermarket part. In stock and ready to ship. Orders placed before 3PM CST ship the same business day nationwide.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model LC350HE400804.\u003c\/p\u003e\n\u003ch2\u003eShipping\u003c\/h2\u003e\n\u003cp\u003eSame-day shipping before 3 PM CST. 30-day returns on uninstalled parts.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Carrier","offers":[{"title":"Default Title","offer_id":62942614520179,"sku":"carrier-pressure-switch-lc350he400804","price":47.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-lc350he400804.jpg?v=1781470455","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-lc350he400804","provider":"National HVAC Parts","version":"1.0","type":"link"}
