Ariston Fan Assembly 999397

A boiler that refuses to fire up is a problem that needs a swift and reliable solution. The fan assembly is a non-negotiable part for safe operation, and if it fails, the entire system will shut down. This genuine Ariston Fan Assembly 999397 is the manufacturer-approved spare part needed to resolve the fault correctly and restore heating and hot water.

Bring Your Boiler Back to Life Safely

The fan motor assembly acts as the lungs of your boiler, performing two essential safety functions: first, it pushes the harmful products of combustion, like carbon monoxide, safely out through the flue. Second, it draws in a precise volume of air to mix with the gas, ensuring the boiler burns cleanly and efficiently. If this component stops functioning correctly, the boiler’s safety checks will prevent it from running, resulting in a lockout. The symptoms are often very clear for a heating engineer. You may hear a loud, irregular rattling or a high-pitched whine from the boiler just before it cuts out, or it may simply fail to initiate the ignition sequence at all. These are sure signs that the fan has reached the end of its life and a replacement is needed.
