The flame sensor is a critical safety component — a small metal rod positioned in the burner flame path that generates a micro-amp DC signal to prove to the control board that ignition has occurred. When the sensor's rod becomes coated with oxidation or the component fails entirely, the furnace will light briefly then shut down within 5–8 seconds, triggering a safety lockout. Repeated short-cycling with no heat output is the most common symptom of a failed flame sensor. Part number \u003cstrong\u003eLH680534\u003c\/strong\u003e is the current OEM replacement for the superseded \u003cstrong\u003eLH33WZ521\u003c\/strong\u003e and includes the factory lead wire harness for direct plug-in installation.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Part Numbers:\u003c\/strong\u003e LH680534 (current) | LH33WZ521 (superseded) — factory-direct replacement, exact fit for PG92SAS48080BAAA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM vs Generic:\u003c\/strong\u003e This genuine Carrier part meets exact micro-amp sensing tolerances specified by the factory.
