Worcester Bosch Fan Assembly CDI Combi 87161210630

The Worcester Bosch 87161210630 is a fan assembly used on Worcester Bosch CDI combi boilers. It draws combustion air into the burner and drives flue gases through the heat exchanger and out to the flue, and it provides the airflow signal the boiler needs before it will light. It is a serviceable component within the combustion circuit, so it is replaced as a complete assembly rather than repaired.

• The boiler locks out or fails to ignite, with a fan or airflow related fault showing on the controls
• Grinding, whining or rumbling noise from the fan area when the boiler starts up
• The fan runs intermittently, runs on after shutdown, or does not run at all when there is a demand for heat
• Repeated overheat or flue-related shutdowns during normal operation
• Visible damage, soot or debris on the fan impeller or housing

• Confirm the boiler model and GC number against the compatibility list; the 35 CDI RSF is listed in both natural gas and LPG versions with different GC numbers.
• Check the part number on the existing fan against 87161210630 and the alternative numbers listed above before ordering.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
• All parts are non-returnable and non-refundable, so ensure the correct part has been selected for the boiler before purchase.
