The flame sensor is a critical safety component — a small rod that detects the presence of a burner flame by passing a small electrical current through it. When the sensor rod becomes coated with oxidation or carbon buildup, it can no longer verify flame presence, causing the control board to shut off the gas valve within 5 to 8 seconds of ignition as a safety precaution. The result: your furnace lights briefly, then locks out, cycling repeatedly without ever achieving a full heating call.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecs:\u003c\/strong\u003e OEM part number LH680014 | Includes pre-attached wire harness | Factory-matched rod diameter and bend angle for proper flame contact | 1\/4\" quick-connect terminal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This factory OEM sensor ensures the correct rod alloy composition and geometry for reliable microamp signal output.
