Glow-Worm 10047391 Printed Control Board
The 10047391 PCB is manufactured to exact original equipment specifications for electrical performance, logic programming, and signal compatibility, ensuring seamless integration with all sensors and actuators in the boiler system. The PCB plays a critical role in maintaining boiler safety and efficiency: it interprets real-time feedback from the system, makes decisions based on programmed control strategies, and executes commands that keep combustion, water flow, and heat delivery within safe and optimal operating limits. Because it also manages diagnostic reporting, the PCB helps engineers identify issues quickly via error codes displayed on the user interface, reducing troubleshooting time and improving service outcomes.
Over time, PCBs can degrade due to electrical surges, moisture ingress, thermal cycling, or component ageing, which may lead to sporadic behaviour, unresponsive controls, ignition failures, or complete system lockouts. A faulty control board can mimic other component failures if it misinterprets sensor data or fails to send correct control signals, potentially causing unnecessary part replacements or misdiagnosis. Replacing a worn or damaged PCB with this genuine Glow-Worm product restores precise system logic, improves operational reliability, and protects other components from the effects of incorrect command sequences. Because the control board interfaces with high- and low-voltage circuits and governs safety-critical functions, installation must be performed by a Gas Safe registered engineer to ensure correct wiring, grounding, and full compliance with electrical and boiler safety standards.
Glow-Worm provide a 1 year warranty on all spare parts. Electrical Deals Direct now sells a wide range of spare parts. If you cannot see the item you require on our website, please call 01934 253600 or email [email protected] for more information.

For all Gledhill Cylinders, a flat delivery charge of £33.00 (ex-VAT) applies, regardless of order value or delivery method. This will be added automatically at checkout.
Returns Information -
Having to return a product because it doesn’t fit, or is not what you wanted, is really annoying! To try and make sure this isn’t necessary we have lots of helpful advice on our site, and you should feel free to call our experts on the number above to check if you are in any doubt at all – we’re always happy to help.
But if you do, don’t worry, just contact us and we’ll get it sorted (note that for trade customers there may be a restocking fee). If you need it, we can usually arrange the carrier to pick it up.
