Without a clean, working sensor the board shuts the gas valve within seconds as a safety measure, producing the classic symptom of a furnace that lights briefly then drops out and short-cycles. A sooted or corroded sensor is one of the most common no-heat callbacks. This genuine Carrier sensor uses the correct rod length, ceramic insulator, and mounting bracket for a precise fit and a reliable flame signal. Installation is one of the easiest furnace repairs: cut power, remove the single mounting screw, unplug the wire, and install the new sensor—about 10 minutes. Avoid touching the metal rod with bare fingers. This part is compatible with Carrier model GB3AAV036035AAJA. In stock and ships same-day when ordered before 3PM CST. End nuisance lockouts and restore steady heat.\u003c\/p\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cp\u003eThis part is compatible with Carrier model GB3AAV036035AAJA.\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":62942737498483,"sku":"carrier-undefined-gb3aav036035aaja","price":24.95,"currency_code":"USD","in_stock":true}],"url":"https:\/\/nationalhvacparts.com\/products\/carrier-undefined-gb3aav036035aaja","provider":"National HVAC Parts","version":"1.0","type":"link"}
