Checking the thermostat
  • You can now inspect the thermostat. This comprises a bimetallic strip which opens or closes a pair of contacts. The contacts may need cleaning as a result of ingress of water.

  • You can clean the contacts with switch cleaner fluid (available in an aerosol) and a small piece of fine emery paper. Ensure that the contacts snap open and closed when you apply light pressure to one side or the other of the bimetallic strip.

  • On this iron, perhaps slightly unusually, there is a second pair of normally closed contacts which may have suffered corrosion. If you know what these are for, please leave a comment on this Instructable. My guess is that they are a safety cut-out to prevent overheating and fire if the iron is left standing flat while switched on.

  • Identify the connections to the element and test the resistance between them with a multimeter. It should be around 30 ohms (this iron is rated at 240V 2KW).
