What it is
This is Glow-worm's combustion fan assembly. It draws in the air needed for combustion and expels flue gases from the appliance, and the boiler will not pass gas to the main burner if the fan is not confirmed working.
Signs this part needs replacing
- Boiler locks out on a fan or airflow fault
- Loud, grinding or rattling noise from the fan
- Fan fails to spin up or run at the correct speed
- No pre-purge airflow detected before ignition
Before you order
- Match the part number printed on your existing fan before ordering
- Isolate electrical power before removing the old fan
- Have this fitted by a Gas Safe registered engineer
