The flame sensor is a critical safety component: it generates a small electrical current through the burner flame to prove ignition to the integrated furnace control (IFC) board. When the sensor is fouled with oxidation or has failed completely, the furnace will light briefly and then shut off after just 5 to 8 seconds, triggering a lockout code. Replacing the flame sensor is one of the most common and cost-effective furnace repairs.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e LH33WZ521 (Flame Sensor) | LH680534 (Flame Sensor w\/Lead) — both are factory-authorized for this model.
