Worcester Greenstar Fan Assembly (Before FD790) – Refurbished | Part No. 87161160670

A faulty fan in a Worcester Greenstar boiler causes ignition failure, intermittent lockouts, and fan-related fault codes. The combustion fan is responsible for drawing fresh air into the burner chamber and safely expelling flue gases — when it fails or slows, combustion cannot take place safely and the boiler shuts down. The Worcester Greenstar Fan Assembly 87161160670 (Refurbished, Before FD790) is the correct replacement for Greenstar CDI, CDI Classic, CDI Classic ErP, i System, 24/28i Junior HE, 12–24 RI HE, 25/30 Si, and Highflow 550 CDI models manufactured before serial number FD790, restoring full combustion airflow and boiler operation.

This is a professionally refurbished genuine Worcester fan assembly — quality-tested by engineers before dispatch. The previous part number was 87172044530. Both are fulfilled by this listing. Original price: £79.99 — current price: £50.29. Supplied with a full 12-month warranty. Important: This part is only suitable for boilers manufactured BEFORE serial number FD790. Verify your boiler serial number before ordering.
