This is the factory OEM flame sensor with wire harness (part# LH680014) for the Carrier GB1AAV036065ADJA gas furnace. The flame sensor is a small metal rod mounted in the burner assembly that detects the presence of a flame by passing a small electrical current through the burner flame. When the sensor becomes coated with oxidation or fails entirely, the control board cannot confirm ignition and shuts the gas valve off as a safety measure — typically within 5 to 8 seconds of burner startup. The result is a furnace that lights briefly and then locks out, leaving your home without heat.
Compatibility: Designed as a direct OEM replacement for Carrier model GB1AAV036065ADJA gas furnaces. Always verify OEM part number LH680014 against your unit's data plate or existing sensor before ordering. Our team is available to confirm fitment — fast shipping means your furnace is back up and running without delay.
