The Baxi 5112430 Fan Assembly is a genuine replacement combustion fan designed to maintain correct airflow through the boiler’s combustion chamber and flue system. This assembly draws in the necessary air for combustion and expels flue gases safely, supporting stable ignition, efficient burning and consistent heat output. When a fan begins to fail, symptoms such as noisy operation, delayed ignition or boiler lockouts can occur, so fitting the correct OEM replacement is essential for reliable and safe performance.

This fan assembly is compatible with Baxi HE and Performa series boilers that reference part number 5112430 in their parts documentation. To ensure proper 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 differ between models and configurations.

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