What it is

The Worcester Bosch 87186672810 is a 24V cable harness used in Greenstar CDi ErP Classic appliances. It is a low-voltage wiring loom that carries control and sensor signals between components inside the boiler, so the control board can read inputs and command the parts it regulates. The harness is supplied as a complete plug-and-play assembly with the connectors already fitted.

Signs this part needs replacing

  • The boiler fails to fire or locks out intermittently with no mechanical fault found elsewhere.
  • Fault codes relating to sensors or control communication appear on the display.
  • The loom shows cracked, brittle or scorched insulation, or heat damage near a connector.
  • Terminals are loose, corroded or pushed back inside the plug housings.
  • Faults appear and disappear when the harness is moved or the casing is tapped.

Before you order

  • Check the GC number on the appliance data badge against the compatibility list before ordering.
  • The alternative number 1031045 may be marked on the original harness.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
