What it is
The Glow-worm 0020058975 is a genuine printed circuit board (PCB) that acts as the boiler's central control. It continuously checks the thermostats, switches and sensors, and enforces the appliance's safety parameters, shutting it down if a fault is detected.
Signs this part needs replacing
- Boiler stops responding to the thermostat or programmer
- Random lockouts or fault codes with no clear cause
- Display blank or unresponsive
- Boiler resets but the same fault keeps recurring
Before you order

- Confirm the board is the fault before ordering — PCBs are usually non-returnable once the seal is broken
- Isolate electrical power fully before removal
- Fitting must be carried out by a Gas Safe registered engineer
