What it is
A gas pilot thermocouple sold by the heating trade as a direct replacement for the Ariston Compact 400 boiler's pilot assembly. It generates a small voltage from the heat of the pilot flame to hold the flame-failure device open, cutting gas supply to the burner if the pilot goes out. This code is listed separately from the M8-threaded T96-450/M8 variant, so the two use different end connections.
Signs this part needs replacing
- Pilot light won't stay alight, or takes several attempts to hold in
- Boiler locks out and needs the ignition sequence repeated more often
- The flame-failure device trips as soon as the control knob is released
- Visible corrosion, discolouration or a kinked probe on the existing thermocouple
Before you order
- Match the full part number and connector end printed on the thermocouple you are removing
- Isolate the gas supply and have a Gas Safe registered engineer carry out the replacement
