What it is
The Glow-worm 0020097400 is a printed circuit board (PCB) used in Ultracom appliances. It is the main control board, handling the electronic sequencing that runs the boiler — reading sensor inputs, driving the fan and pump, and managing ignition and modulation. As a factory-fitted control component, it is matched to the Ultracom platform rather than being a generic board.
Signs this part needs replacing
- The boiler fails to respond to a demand for heat or hot water, with no fan or pump activity.
- Repeated lockouts that clear on reset but return shortly afterwards.
- No display, blank display, or erratic fault codes that do not match the actual fault condition.
- Fan, pump or gas valve not being driven despite the boiler being powered.
- Visible damage to the board — scorching, burnt tracks, swollen capacitors or corrosion from water ingress.
Before you order
- Check the part number on the existing board matches 0020097400, as board revisions can differ between Ultracom variants.
- Confirm the appliance model and GC number from the data badge before ordering.
- Inspect the board housing and surrounding seals for signs of water ingress, as the underlying cause should be corrected at the same time.
- Work on the boiler's electrical controls should be carried out by a competent person, with the appliance isolated at the supply before the board is removed.
