It generates a microamp signal proving flame is present; without it, the control board shuts off gas as a safety measure, causing short-cycling, no-heat calls, or repeated lockouts. A weak, cracked, or carbon-fouled flame sensor is one of the most common causes of intermittent heating failures. This direct-replacement rod restores reliable flame proving and steady furnace operation. Engineered to exact Carrier specifications, it ensures correct rod length, mounting, and electrical signal for the LC348TM402290. Installation is easy — a 15-minute job for most homeowners and a routine swap for any technician: shut off power, remove one screw, unplug the lead, and reverse. No recalibration required. Genuine Carrier quality means proper fit and long service life. In stock and ships same-day on orders placed before 3PM CST. Keep your furnace running safely through every heating season with the correct OEM flame sensor.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model LC348TM402290.\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":62942616158579,"sku":"carrier-undefined-lc348tm402290","price":24.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-flame-sensor-carrier-undefined-lc34_8a8e6037-b621-4a00-89fa-294265967c5a.jpg?v=1781469106","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-lc348tm402290","provider":"National HVAC Parts","version":"1.0","type":"link"}
