What it is

The Worcester Bosch 87161134110 is a dual thermostat supplied for Worcester Bosch Greenskies appliances. It monitors and regulates temperature within the appliance so that heating and hot water production stay within safe operating limits. The component sits within the thermostats, thermistors and sensors group of Worcester spare parts, and is the part to specify when the existing thermostat is reading or responding incorrectly.

Signs this part needs replacing

  • Heating or hot water temperature drifting away from the setting on the controls
  • The appliance cycling on and off more often than it used to
  • Intermittent heating or hot water, with the appliance cutting out before reaching temperature
  • Temperature readings that do not match the appliance display or the actual system temperature
  • Fault codes or lockouts linked to temperature sensing

Before you order

  • Confirm the part number 87161134110 against the appliance data badge or the existing component before ordering
  • Check the alternative number 1021889 where an older reference is listed for the same component
  • Verify the appliance model against the compatibility list below, as fitment is limited to the Greenskies range
  • Work on the appliance should be carried out by a competent person, with the appliance isolated and made safe before any component is removed
