It is a genuine item that is supplied by the original equipment manufacturer. This part is made for use with kerosene forced air heaters. The thermostat acts as a sensor which protects the unit from overheating. Unfortunately, over time it may wear out, get damaged or stop working all together eventually requiring a replacement. Note, this high-quality thermostat limit control is sold individually. To replace it, you will need a screwdriver to take the housing apart. Make sure to refer to the owner's manual and the appropriate diagrams for your model to ensure the correct application.
