{"product_id":"carrier-undefined-gb1aav042091acja","title":"OEM Carrier Flame Sensor for Model GB1AAV042091ACJA Gas Furnace","description":"\u003cdiv\u003e\n\u003ch1\u003eOEM Carrier Flame Sensor for Model GB1AAV042091ACJA Gas Furnace\u003c\/h1\u003e\n\u003cp\u003eKeep your Carrier GB1AAV042091ACJA furnace heating safely with this genuine OEM flame sensor. The flame sensor verifies that the burner has actually ignited by detecting the flame's micro-amp signal; if it doesn't sense flame within seconds, the control board closes the gas valve to prevent a dangerous gas buildup. A dirty, corroded, or cracked flame sensor is the leading cause of furnaces that light and then shut down after a few seconds (short-cycling on flame failure). This factory-spec rod matches the exact length, bend, mounting bracket, and terminal of the original on the GB1AAV042091ACJA for a perfect fit and accurate flame rectification. Installation is easy and beginner-friendly: cut power, remove one mounting screw, unplug the wire, and swap in the new sensor in about 10-15 minutes. No calibration required. Replacing a worn flame sensor restores reliable startups and eliminates frustrating no-heat lockouts. Engineered specifically for your Carrier model, not a universal compromise. 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 GB1AAV042091ACJA.\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":62942795202931,"sku":"carrier-undefined-gb1aav042091acja","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_85deab33-4824-4410-b6e7-c5302ed2d61d.jpg?v=1781469003","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-gb1aav042091acja","provider":"National HVAC Parts","version":"1.0","type":"link"}
