A stuck-open or failed switch commonly causes a no-heat condition, a pressure switch error code, or an inducer that runs while the burners never fire. Built to the exact specification of Carrier model LC350HE400811, this switch detects the proper negative pressure from the draft inducer motor and closes its contacts to safely allow ignition. Replacement is a manageable DIY job of roughly 20 to 30 minutes: shut off power, note and remove the wiring and hose, install the new switch, and reconnect everything. Genuine OEM construction ensures the precise pressure setpoint your model demands, avoiding the false trips and unsafe cycling that universal switches often introduce. Restore safe, reliable heating and peace of mind. Orders placed before 3PM CST ship same-day for quick turnaround. Choose authentic Carrier parts for dependable safety and durability that lasts.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model LC3:50HE400811——.\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":62942612619635,"sku":"carrier-pressure-switch-lc3-50he400811","price":48.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-lc3-50he400811.jpg?v=1781470464","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-lc3-50he400811","provider":"National HVAC Parts","version":"1.0","type":"link"}
