This OEM Carrier flame sensor (LH680534) confirms the presence of a burner flame on your GB3AAV048095ADJA gas furnace, signaling the control board to keep the gas valve open. When a flame sensor becomes coated or fails, the furnace lights briefly then shuts down, leaving you without heat. Replacing it restores reliable ignition and continuous, safe operation. This is a direct-fit replacement engineered to exact Carrier specifications for the GB3AAV048095ADJA, ensuring proper rod length, mounting, and electrical contact. Installation is easy and typically takes under 15 minutes with a single screwdriver—remove the old sensor, seat the new one, and reconnect the lead. No special tools or recalibration required, making it a great DIY repair. Always shut off power and gas before servicing. Genuine Carrier components deliver the durability and performance that aftermarket parts can't match. In stock and ready to ship same-day when you order before 3PM CST, so you can get your heat back fast. Order with confidence from NationalHVACParts.com.
