When the sensing rod oxidizes or cracks, the board can't verify the flame and shuts off gas—causing short-cycling, repeated lockouts, or a furnace that lights then quickly dies. This sensor is an exact direct-fit replacement for the Carrier GB1AAV036045AFJA gas furnace, with the same probe length, bracket, and terminal as the factory part. Installation is easy for most DIY homeowners: shut off power, remove one screw, unplug the spade connector, and swap in the new rod. Cleaning a corroded sensor is only a temporary fix—a worn rod should be replaced to restore reliable starts. The genuine OEM part ensures proper flame rectification and avoids the nuisance faults common with generic rods. In stock and ships same-day when you order before 3PM CST. Bring back safe, dependable heat with the exact flame sensor Carrier built for your furnace.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV036045AFJA.\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":62942821089651,"sku":"carrier-undefined-gb1aav036045afja","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-gb1a_812e68d9-3547-4400-a45e-95bb0f66bb21.jpg?v=1781469129","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-gb1aav036045afja","provider":"National HVAC Parts","version":"1.0","type":"link"}
