The pressure switch is a vital safety device that verifies proper venting and inducer draft before permitting the igniter and gas valve to fire. If it detects a blocked vent, weak draft, or condensate backup, it stops ignition to prevent dangerous flue gas spillage into the home. A stuck or failed switch causes lockouts, error codes, and no-heat conditions. This factory-spec replacement matches the original pressure setpoint, hose port, and electrical terminals for a true direct fit. Installation is a moderate DIY task of roughly 15-20 minutes, transferring the rubber hose and two wires after cutting power. Using the correct OEM-rated switch is essential, since an incorrect setpoint defeats a key safety function. Restore safe, reliable furnace operation with a part built to factory standards rather than an uncertain aftermarket substitute. In stock and ready to ship. Orders placed before 3PM CST ship the same business day.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model LC350HE400803.\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":62942614618483,"sku":"carrier-pressure-switch-lc350he400803","price":47.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-lc350he400803.jpg?v=1781470453","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-lc350he400803","provider":"National HVAC Parts","version":"1.0","type":"link"}
