What it is

The Broag high limit thermostat 110°C RA is a safety temperature control device used on Broag Commercial boilers. It monitors boiler temperature and interrupts the burner circuit if the set limit is reached, protecting the appliance from overheating. The part carries the Ranco reference L07 P4005.

Signs this part needs replacing

  • The boiler repeatedly locks out or trips on overheat
  • The high limit device fails to reset after the boiler has cooled
  • Burner shuts down before the boiler reaches its normal operating temperature
  • Temperature control becomes erratic, with the appliance cycling on and off unexpectedly
  • Visible damage, corrosion or a loose or broken capillary/connection at the thermostat

Before you order

  • Confirm your boiler model against the manufacturer's parts list
  • Check the existing thermostat markings and temperature rating match 110°C
  • Verify the Ranco reference L07 P4005 against the part fitted to the appliance
  • Isolate the electrical supply and allow the boiler to cool before inspection or removal
