What it is

The Worcester Bosch adaptor mixing chamber to fan, part 87161065470, is a connector that links the mixing chamber to the fan assembly inside the appliance. It sits in the fan section, where the fan draws fresh air into the combustion chamber so the gas burns correctly and then carries the combusted gases away once combustion is complete. It is a Worcester Bosch spare intended for the Greenstar family of boilers.

Signs this part needs replacing

  • The boiler locks out or fails to fire, with fan or combustion related fault codes showing.
  • The fan runs but the appliance will not establish a stable flame.
  • Whistling or unusual air noise around the fan inlet area.
  • Cracks, distortion or a loose fit where the adaptor meets the mixing chamber or fan.
  • Soot or condensate staining around the fan section of the appliance.

Before you order

  • Check the appliance model and GC number against the compatibility list, as this part number covers a number of Greenstar variants.
  • Confirm the part number on the existing component or in the boiler documentation before ordering.
  • This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
