The Worcester Bosch 87161164740 Fan Assembly is a genuine replacement combustion airflow component engineered to maintain correct air movement through the boiler’s combustion chamber and flue system. This fan draws in the air required for efficient combustion and safely expels flue gases, supporting stable ignition, consistent burner performance and reliable heat output. When the original fan becomes worn, noisy or begins to fail, your boiler may experience ignition delays, unusual noises, reduced performance or safety lockouts, so fitting the correct OEM fan assembly is essential for restoring dependable, safe operation.

This fan assembly is compatible with Worcester Bosch Greenstar, Highflow and RD series boilers that reference part number 87161164740 in their technical documentation. To ensure correct fitment and optimal performance, always verify the part number on your existing fan or consult your boiler’s service information before installation, as airflow components vary between models and configurations.

Supplied ready for direct replacement, the 87161164740 Fan Assembly integrates with the boiler’s original mounting points and electrical connections without modification when installed by a qualified engineer. Choosing this genuine Worcester Bosch component helps restore proper combustion airflow, improve ignition reliability and support consistent heating and hot-water performance in compatible Greenstar, Highflow and RD boilers.
