Shop Ariston boiler fans for selected Clas, Genus, E-Combi and Microgenus models. A faulty fan can cause ignition failure, unusual noise or boiler lockout. Before ordering an Ariston replacement fan, check the boiler model, GC number and part number printed on the existing component to confirm compatibility.
The fan supplies combustion air and helps move flue gases safely out of the boiler. If it runs too slowly, becomes noisy or fails to send the correct speed signal, the boiler may stop firing.
The Ariston 612 fault code is commonly linked to fan-speed problems, although damaged wiring, restricted airflow or a PCB fault can cause similar symptoms. Read our Ariston 612 fault code guide for more information.
Fan and flue checks require a Gas Safe registered engineer. Confirm the full boiler model, GC number and existing fan part number before ordering.
