Over time the sensor rod accumulates a silicon-oxide coating that weakens its microamp signal, causing the furnace to light briefly then shut down — the classic short-cycling complaint. When cleaning no longer restores a reliable signal, replacement is the fix. This genuine Carrier-specified sensor is built to the correct rod length and mounting geometry for your burner assembly, ensuring proper flame rectification. Installation is an easy DIY task: turn off power and gas, remove the single mounting screw, disconnect the sensor wire, install the new sensor, and reconnect. Most replacements take 15 minutes. Using the OEM sensor guarantees the precise positioning the flame requires for a stable signal. In stock and ships same-day when you order before 3PM CST, so you can stop the short-cycling fast. Order now to restore safe, continuous heating.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV042091AEJA.\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":62942793793907,"sku":"carrier-undefined-gb1aav042091aeja","price":34.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/1190\/5395\/files\/nhvac-flame-sensor-carrier-undefined-gb1a_104cb109-d1d8-4fdc-916a-84f7545c7247.jpg?v=1781469510","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-gb1aav042091aeja","provider":"National HVAC Parts","version":"1.0","type":"link"}
