What it is

The Worcester Bosch Wiring Harness 3 Way (Service) is a three-way electrical harness supplied by Worcester Bosch as a service part under part number 87161126940. It forms part of the appliance wiring on compatible Greenstar oil-fired boilers, carrying connections between the boiler's electrical components. It is listed under the Worcester Bosch service parts range.

Signs this part needs replacing

  • Intermittent electrical faults or the boiler cutting out without a clear cause
  • Visible damage to the harness, such as cracked insulation, chafing or a broken conductor
  • Discolouration, scorching or a loose fit at the harness plug connections
  • Faults that appear or disappear when the harness or its connectors are moved

Before you order

  • Confirm the boiler model and range match those listed in the Fits section
  • Check the existing harness routing and connector arrangement before removal
  • Inspect the harness plugs for damage so any related faults are identified at the same time
  • Have the appliance isolated from the electrical supply before fitting
