What it is

The Glow-worm 0020186176 wiring harness is a replacement loom for Glow-worm combi boilers, listed under the supplied product name WIRING HARNESS. It carries control and sensor wiring between the boiler's main PCB and the components it serves. It is used across a number of Glow-worm combi models, including the Easicom 2 24C.

Signs this part needs replacing

  • Insulation that is cracked, chafed or heat-damaged along the run of the loom.
  • Connectors that are burnt, corroded, loose or pushed back on the PCB or component terminals.
  • Intermittent faults, lockouts or error codes that appear or clear when the loom is moved.
  • Components failing to receive power or signal where harness continuity is broken.
  • Abrasion or rodent damage where the loom passes through casing grommets.

Before you order

  • Check the boiler model and GC number against the fit list above; not every Glow-worm combi uses this loom.
  • Confirm the part number marked on the existing harness matches 0020186176.
  • Compare connector count, shape and pin layout on the old loom with the new part before fitting.
  • Isolate the appliance electrically and work to the manufacturer's wiring diagram.
