When the sensor is dirty, oxidized, or worn out, the furnace ignites and then shuts off within seconds, causing repeated short cycling and inconsistent warmth. This factory-spec replacement is precision-matched to Carrier model LC350LC400678, delivering proper flame rectification and a strong microamp signal for safe operation. Manufactured to OEM tolerances, it restores accurate flame detection and ends frustrating nuisance lockouts. Installation is one of the simplest furnace repairs—generally 15-20 minutes with a single mounting screw and one wire connector, well suited to a careful DIYer, though a licensed professional is recommended if you have any doubt. Enjoy steady, dependable heat with a component engineered to factory standards instead of a generic alternative. Every order placed before 3PM CST ships same-day, returning your Carrier furnace to service quickly. Trust authentic OEM quality for safe, consistent flame sensing all heating season long.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model LC350LC400678.\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":62942608392563,"sku":"carrier-undefined-lc350lc400678","price":19.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-flame-sensor-carrier-undefined-lc35_c6010e5b-a21d-4988-8720-ace8d8d9ae26.jpg?v=1781469240","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-lc350lc400678","provider":"National HVAC Parts","version":"1.0","type":"link"}
