A dirty or cracked flame sensor is the most common cause of short-cycling and ignition lockout on the Carrier GB1AAV042075AAJA furnace. This is a direct factory-fit replacement engineered to the exact resistance and mounting specs of your unit, ensuring reliable rectification and flame proving. Installation is an easy DIY job for most homeowners: power off the furnace, remove the burner-compartment screw, unclip the wire, and swap the sensor in under 15 minutes — no special tools required. Always handle the rod by the ceramic base to avoid contamination. Restore consistent, safe heating and eliminate nuisance lockouts with the correct OEM part. In stock and ships same-day when your order is placed before 3PM CST, so you can get your furnace running fast.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB1AAV042075AAJA.\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":62942797365619,"sku":"carrier-undefined-gb1aav042075aaja","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_61932636-0cf0-4e49-868b-a99158b1ffdc.jpg?v=1781469145","url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-gb1aav042075aaja","provider":"National HVAC Parts","version":"1.0","type":"link"}
