What it is

The Warmflow high limit thermostat is a safety control fitted to Warmflow oil-fired combi boilers. It monitors boiler temperature and interrupts the burner demand if the set limit is exceeded, preventing the appliance from overheating. This item is listed under Warmflow part reference LM7 and P5113000.

Signs this part needs replacing

  • The boiler locks out repeatedly and requires resetting after reaching temperature.
  • The high limit trips even when the boiler is not running hot.
  • The burner cuts out early and the appliance fails to reach its normal operating temperature.
  • The boiler fires briefly and then shuts down, cycling without completing a demand.
  • No heating or hot water because the limit stat remains open.

Before you order

  • Confirm your boiler model against the manufacturer's parts list.
  • Check the part reference on the existing thermostat matches LM7 or P5113000.
  • Isolate the electrical supply to the appliance before removing or fitting any control.
  • Check the thermostat sensor and capillary are undamaged and correctly seated before ordering a replacement.
