This genuine OEM Carrier flame sensor is a critical safety component on your LC3:50HE400808 high-efficiency gas furnace. Mounted in the burner assembly, the flame sensor confirms that the burner has actually ignited by detecting the flame's micro-current. If it fails to sense flame, the control board shuts off the gas valve to prevent dangerous gas buildup. A dirty, corroded, or cracked flame sensor is a leading cause of furnaces that light briefly then shut down, repeated short cycling, and ignition lockout codes. This factory-spec replacement matches the original rod length, bracket, and connector for accurate flame detection and trouble-free heating. Installation is easy and homeowner-friendly—typically 10-15 minutes with a single screw and a quick wire disconnect. Always turn off power and gas first. Restore reliable, safe heat and stop frustrating no-heat cycling with this OEM-quality sensor. Ships same-day when ordered before 3PM CST.
