What it is
The Sime 5181502 is a combined thermocouple and high limit thermostat assembly for Sime gas boilers. The thermocouple holds the gas valve open while the pilot flame is established, and the high limit thermostat cuts the gas supply if the boiler overheats. It is supplied as a complete assembly for the Sime Murelle and Friendly ranges.
Signs this part needs replacing
- Pilot flame will not stay lit when the control knob is released
- Boiler locks out shortly after ignition
- No heating or hot water despite the pilot being lit
- High limit thermostat trips repeatedly
- Visible damage or corrosion on the thermocouple probe or capillary
Before you order
- Check your boiler model and serial number against the fits list above
- Confirm the existing assembly is a combined thermocouple and high limit thermostat
- Consult the manufacturer's parts list if your model is not listed
