What it is
The Glow-worm S227033 is a Sifan fan assembly, referenced FFB1701 030, used in Micron FF appliances. It draws combustion air through the heat exchanger and drives flue products out through the flue, maintaining the airflow the burner needs to run correctly. The fan is part of the combustion circuit and is controlled by the appliance's board, so its speed and operation are tied directly to ignition and flame supervision.
Signs this part needs replacing
- Boiler locks out or fails to ignite, with a fan or air pressure fault indicated
- Fan noisy on start-up or while running — rumbling, scraping or squealing
- Intermittent ignition or flame failure once the fan has run
- Impeller stiff, loose or catching when turned by hand
- Overheating or flue-related lockouts traced back to reduced airflow
Before you order
- Confirm the appliance model and the part number marked on the existing fan
- Check the GC number on the appliance data badge against the model
- Inspect the fan gasket and sealing washers and replace them if compressed or perished
