It monitors draft from the inducer motor and tells the control board it is safe to ignite; when the switch fails or sticks, the furnace short-cycles or refuses to start, often showing a pressure-switch lockout fault. This factory part is calibrated to the exact trip point your furnace requires, restoring correct, safe sequencing without the false trips common to generic substitutes. It is a direct-fit replacement for Carrier model LC350HE400800, matching the original port configuration and electrical terminals. Installation is straightforward for a confident DIYer: cut power, label and transfer the hose and wire connections, and mount the new switch in the same location, usually 20 to 30 minutes. Always verify the vent and hoses are clear of condensate before reassembly. Order before 3PM CST and this pressure switch ships the same business day from stock, so you can clear the fault and restore heat quickly.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model LC350HE400800.\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":62942615568755,"sku":"carrier-pressure-switch-lc350he400800","price":44.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-lc350he400800.jpg?v=1781470408","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-lc350he400800","provider":"National HVAC Parts","version":"1.0","type":"link"}
