What it is

The Worcester Bosch main wiring harness, part 87161126100, is the loom that connects the appliance's electronic control board to its thermostats, sensors and switches. Wiring inside a Worcester Bosch heating appliance groups the individual conductors into a single harness, which keeps routing tidy and makes the control board's connections easier to trace during fault finding. Through this loom the printed circuit board reads the appliance's inputs and enacts its safety protocols and heating control.

  • Error codes pointing to sensors or controls that test correctly at the component
  • The appliance fails to respond when the controls are operated
