What it is
The Worcester Bosch high voltage wiring harness, part number 87186900880, is an electrical loom used on the Greenstar Heatslave II family of oil-fired condensing boilers. It carries the high voltage connections between the boiler's electrical components, so power reaches the burner, controls and associated parts along the intended route. It is a service part intended for replacement where the original harness is damaged or faulty.
Signs this part needs replacing
- The boiler fails to power up, or power is intermittent
- The burner or controls cut out and reset without an obvious fault elsewhere
- Insulation on the existing harness is chafed, brittle or heat-affected
- Connector terminals are loose, corroded or discoloured
- Continuity or voltage faults traced along the harness rather than to a component
Before you order
- Confirm the boiler model against the fitment list above
- Check the part number printed or moulded on the existing harness matches 87186900880
- Compare the connector layout and pin count of the old harness with the replacement
- Isolate the electrical supply to the appliance before removing or refitting the harness
