The Baxi 5112430 Fan Assembly is a genuine replacement combustion airflow component designed to maintain the correct movement of air through your boiler’s combustion chamber and flue system. By drawing in the air needed for efficient combustion and expelling flue gases safely, this fan supports reliable ignition, stable burner performance and consistent heat output. When the original fan becomes worn, noisy or begins to fail, boilers can experience ignition delays, unusual noises or safety lockouts, so fitting the correct OEM assembly is essential for restoring dependable and safe operation.

This fan assembly is compatible with Baxi HE and Performa series boilers that specify part number 5112430 in their parts 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 combustion airflow components vary between models and configurations.

Supplied ready for direct replacement, the 5112430 Fan Assembly connects with the boiler’s existing mounting points and electrical harness without modification when installed by a qualified engineer. Choosing this genuine Baxi component helps restore proper combustion airflow, improve ignition reliability and support dependable heating performance in compatible HE and Performa boilers.
