The flame sensor is a safety-critical component: a small rod positioned in the burner flame that passes a micro-amp current through the flame to prove ignition. When it fails — typically due to oxidation or carbon buildup on the sensing rod — the control board cannot confirm a lit burner and will shut off the gas valve within 5–8 seconds, causing the frustrating symptom of a furnace that lights briefly, then immediately shuts down and locks out.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Numbers:\u003c\/strong\u003e LH680534 (primary, with lead wire) | LH33WZ521 (superseded OEM number — LH680534 is the direct factory replacement)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This is a genuine Carrier factory part with the pre-attached lead wire included (LH680534), ensuring exact connector fit and factory-spec rod geometry.
