A stuck, drifted, or failed pressure switch triggers lockouts, blinking error codes, and no-heat conditions even when everything else works. This OEM replacement is calibrated to the precise actuation point your furnace requires, ensuring reliable combustion safety that miscalibrated aftermarket switches cannot match. Built to factory standards, it restores correct sequencing and protects against dangerous incomplete venting. Installation is a moderate, accessible repair: shut off power, disconnect the wire terminals and the rubber hose, remove the mounting screws, and fit the new switch in about 20 minutes. Verify the hose is clear of condensate during the swap. Get dependable, safe furnace startups again with a switch matched exactly to the LC350TM400675. We stock these and ship same-day on orders before 3PM CST, so your heat is restored quickly. Choose authentic Carrier quality for safe, code-compliant operation.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model LC350TM400675.\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":62942604034419,"sku":"carrier-pressure-switch-lc350tm400675","price":42.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-pressure-switch-lc350tm400675.jpg?v=1781470646","url":"https:\/\/nationalhvacparts.com\/products\/carrier-pressure-switch-lc350tm400675","provider":"National HVAC Parts","version":"1.0","type":"link"}
