When oxidation builds up on the rod, your furnace ignites for a few seconds then shuts down and retries — the textbook short-cycling no-heat symptom. Light buildup can be cleaned, but a pitted, burned, or cracked sensor needs replacement to deliver a steady flame signal. This genuine Carrier sensor produces the exact microamp current your board requires, eliminating the false flame-loss lockouts that cheap aftermarket rods commonly cause. It installs with a single screw in the original spot and plugs into the existing lead. Installation is easy — shut off power, remove one screw, disconnect the wire, and fit the new sensor without touching the rod with bare fingers. Most homeowners finish in 10 to 15 minutes. Since this is a common maintenance item, keeping a spare avoids a cold-night scramble. 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 GB1AAV048075AAJA.\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":62942787142003,"sku":"carrier-undefined-gb1aav048075aaja","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_65600bcd-297d-40cd-b7b0-018469cc45d8.jpg?v=1781469112","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-gb1aav048075aaja","provider":"National HVAC Parts","version":"1.0","type":"link"}
