OEM Carrier Flame Sensor LH680013 for Model PG9MAA036060ADKA

This OEM flame sensor (part number LH680013) is the factory-specified replacement for the Carrier PG9MAA036060ADKA gas furnace. The flame sensor — also called a flame rod — is a safety device mounted in the burner assembly that detects the presence of a live flame by passing a small electrical current through the combustion gases. When the sensor's rod becomes coated with oxidation or carbon buildup, its ability to conduct that signal degrades. The control board interprets this as a flame failure and shuts off the gas valve, typically 5 to 8 seconds after ignition — causing the frustrating "lights then immediately shuts off" symptom that most homeowners and technicians recognize immediately.
