What it is

The Ariston 200166 is a thermocouple supplied by Ariston. It is a flame-supervision device used in gas-fired heating appliances: while the burner flame is present it generates a small voltage that holds the gas valve open, and it closes the valve when the flame is lost. It is a general service component rather than an appliance-specific spare.

Before you order

  • Check that the part number 200166 matches the thermocouple being replaced.
  • Confirm the appliance is gas-fired and that a thermocouple is the correct flame-supervision component for it.
  • Compare the connection type and lead length against the existing thermocouple, as these are not stated for this part.
