What it is

The Glow-worm thermocouple is supplied under part number S900004. It is a flame-sensing device used in gas appliance control circuits, generating a small voltage while a flame is present to hold the gas valve open.

Before you order

  • Check that the part number S900004 matches the reference on the component being replaced or in the appliance documentation.
  • Compare the physical form of the thermocouple — overall length, probe and connection type — against the item being replaced.
  • Gas appliance work must be carried out by a competent person in accordance with current UK regulations.
