What it is

The Worcester Bosch high limit thermostat, part number 87161076230, is a safety temperature control fitted to Worcester Bosch oil-fired boilers. It monitors the temperature at its sensing point and interrupts the burner when that temperature rises beyond the designed limit, protecting the heat exchanger and surrounding components from overheating. It sits within the Thermostats, Thermistors & Sensors group of Worcester spare parts and is used across the Greenstar and Camray oil ranges.

Signs this part needs replacing

  • The boiler locks out or shuts down shortly after the burner fires
  • The appliance needs repeated manual resets to keep running
  • The burner cuts out well before the appliance reaches its normal operating temperature
  • Overheat symptoms appear with no other obvious cause in the heating circuit
  • The thermostat shows no switching response as the appliance warms up

Before you order

  • Confirm the appliance model and GC number against the compatibility list before ordering
  • Compare the part number on the existing thermostat, or the alternative number 1021104, with the numbers listed here
  • Check whether any seal, gasket or retaining clip disturbed during removal also needs replacing
  • Any work inside an oil-fired appliance should be carried out by a competent engineer
