What it is
The Worcester Bosch 87172044100 is a complete fan assembly for the Greenstar FSN-GB combi boiler range. It draws combustion air into the burner and pushes flue gases out through the flue system, so the appliance can maintain a stable, correctly balanced burn throughout its operating cycle. The assembly is supplied as a single unit covering the fan housing and impeller arrangement used on these models.
Signs this part needs replacing
- The boiler locks out or fails to fire, with the fan failing to run at start-up
- Grinding, rumbling or scraping noise from the fan area during operation
- Intermittent running or a fan that spins up and then drops out
- Repeated lockout codes linked to air pressure or flue proving
- Visible damage, contamination or stiffness when the fan is turned by hand
Before you order
- Check the GC number on the appliance data badge against the compatibility list to confirm the correct fan assembly
- Confirm the part number on the existing fan, including any previous number still shown on older stock
- Inspect the fan mounting gasket and sealing washers, and replace them if they are compressed or perished
- This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
