What it is

The gas sensor connector is a Worcester Bosch wiring component used on Greenstar FS regular gas boilers. It links the gas sensor circuit to the appliance's control harness, carrying the signal the boiler needs to monitor combustion conditions. It is supplied as a single connector assembly under part number 87186814080.

Signs this part needs replacing

  • Boiler locks out or fails to fire despite a healthy gas supply and ignition spark
  • Intermittent flame or combustion faults that clear when the wiring loom is disturbed
  • Corroded, discoloured or heat-damaged pins in the connector body
  • Loose or poor contact at the sensor plug, causing erratic readings or repeated reset attempts
  • Fault codes relating to the gas sensor circuit appearing during a service call

Before you order

  • Check the appliance GC number and serial plate against the compatibility list before ordering, as several Greenstar FS variants use different looms
  • Confirm the part number on the existing connector matches 87186814080 or the alternative number 1022645
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
