When the sensor is coated in oxidation, your furnace lights for a few seconds then shuts off and retries — the classic short-cycle no-heat complaint. While cleaning sometimes helps, a pitted or cracked sensor must be replaced to restore a stable flame signal. This genuine Carrier sensor delivers the precise microamp output your control board expects, ending the false flame-loss lockouts that off-brand rods often trigger. It mounts with a single screw in the original location and connects to the existing lead. Installation is easy — power off, remove one screw, unplug the wire, and seat the new sensor without touching the rod with bare fingers. Most homeowners finish in 10 to 15 minutes. It's smart to keep a spare on hand since this is a common wear item. Order before 3PM CST and your flame sensor ships same-day.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV048090AAJA.\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":62942787010931,"sku":"carrier-undefined-gb1aav048090aaja","price":18.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-flame-sensor-carrier-undefined-gb1a_166fd14d-4023-4036-83f7-3f21f9330c6c.jpg?v=1781469114","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-gb1aav048090aaja","provider":"National HVAC Parts","version":"1.0","type":"link"}
