What it is

The Worcester Bosch 87161423620 is a thermostat timer disc supplied by Worcester Bosch for its older gas boiler range. It forms part of the appliance's temperature control circuit, sensing heat within the boiler and switching the burner cycle in step with the timer setting. The disc is a serviceable control component, so it is replaced as a unit when the switching behaviour drifts or fails.

Signs this part needs replacing

  • The boiler keeps running after the timer or programmer has switched the demand off
  • The appliance fails to fire when heat is called for
  • Room temperature drifts well above or below the setting on the control
  • Short, erratic burner cycles rather than steady running
  • No change in boiler behaviour when the timer dial is adjusted

Before you order

  • Check the GC number and the appliance data badge to confirm the disc suits your model before ordering.
  • Older stock and documentation may carry the previous number SPK0088 in place of 87161423620.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
