The flame sensor is a critical safety component — a metal rod that detects the presence of a burner flame by passing a small microamp current through the flame itself. When the sensor's rod becomes coated with oxidation or mineral buildup, or fails entirely, the furnace control board can no longer confirm ignition and will shut off the gas valve within 5–8 seconds as a safety lockout. The result: the burner lights briefly, then the furnace goes through repeated ignition attempts before locking out entirely.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e LH680014 | Includes factory wire harness | 45-degree rod orientation | High-temperature Kanthal flame rod material | Compatible with HSI (Hot Surface Ignition) systems\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This OEM unit is built to Carrier's exact microamp sensing threshold and rod geometry.
