What it is
The Ariston 999397 is a fan assembly supplied by Ariston for its Microgenus and Microgenus Plus wall-mounted boiler range. It moves air through the combustion circuit and drives flue gases out through the terminal, running whenever the appliance fires. The unit is rated at 52 W and connects on the right-hand side through a DN 60 mm spigot.
Signs this part needs replacing
- The appliance locks out or fails to fire, with a fan-related fault code showing
- Grinding, whining or rattling noise coming from the fan housing
- Weak or absent flue gas flow, causing the boiler to shut down shortly after ignition
- The fan runs intermittently, or not at all, when there is a call for heat
- Visible play, damage or heavy contamination on the impeller or bearings
Before you order
- Confirm part number 999397 against the appliance data badge or the label on the original fan.
- Check the full model name and serial number, as the Microgenus family covers several variants that do not all share the same fan assembly.
- Inspect the fan gasket and mounting seals while the appliance is open, and replace any that are compressed or perished.
