What it is

The Worcester Bosch wiring harness for the flue sensor (part number 87161079420) is a replacement electrical lead that connects the flue sensor to the boiler's control system. It is supplied as part of the Worcester oil boiler spares range and is used on the Greenstar Heatslave HE internal series.

Signs this part needs replacing

  • Flue sensor fault or error code displayed on the boiler controls
  • Boiler locking out or shutting down on a flue temperature fault
  • Intermittent or erratic flue sensor readings that clear when the harness is moved
  • Visible damage to the harness, such as cracked insulation, chafing or heat-affected cable
  • Corroded or loose terminals at the sensor or control plug

Before you order

  • Check the boiler data badge to confirm the model matches one of the listed Greenstar Heatslave HE internal variants
  • Inspect the existing flue sensor and its connector for damage before replacing the harness alone
  • Confirm the fault is traced to the harness rather than the sensor itself
