If genuine flame isn't sensed within a few seconds of ignition, the board immediately closes the gas valve to stop the flow of unburned gas—making this slender rod one of the furnace's most essential safety devices. As a genuine Carrier part, the LH680534 is manufactured to the exact length and conductivity specs of the GB3AAV048075AAJA for precise, dependable detection. A dirty or worn flame sensor is the leading cause of short cycling, where the burners light and then shut off seconds later. Replacement is a simple DIY task: remove one screw, swap the sensor, and reconnect the lead in roughly 10 minutes. Order before 3PM CST and it ships same-day. Get reliable heat back with this factory-authorized Carrier flame sensor engineered specifically for your unit.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB3AAV048075AAJA.\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":62942727504243,"sku":"carrier-undefined-gb3aav048075aaja","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-gb3a_966e84d7-b51b-40bf-9997-bedbe78a2c91.jpg?v=1781469189","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-gb3aav048075aaja","provider":"National HVAC Parts","version":"1.0","type":"link"}
