The flame sensor is a critical safety component — a metalium rod mounted in the burner assembly that conducts a small microamp current through the flame to prove ignition. If the sensor is coated with oxidation or has failed, the furnace control board cannot confirm flame presence and will shut off the gas valve within 5–8 seconds of each ignition attempt, causing the classic short-cycling \"lights then goes out\" symptom. This updated OEM part ships as \u003cstrong\u003eLH680534 (Flame Sensor with Lead)\u003c\/strong\u003e and is the factory-authorized successor to the original \u003cstrong\u003eLH33WZ521\u003c\/strong\u003e.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e LH680534 (current) | LH33WZ521 (superseded) — direct factory replacement, no modifications required\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e Genuine Carrier OEM sensors are manufactured to exact microamp threshold tolerances.
