Glowworm S900847 PCB (TPO 7 Wire / 2 Fuse) – Genuine Glowworm & Protherm Spare Part
The Glowworm S900847 PCB is a genuine printed circuit board used in a wide range of Glowworm and Protherm CI boilers. This PCB includes the TPO 7-wire harness and dual-fuse configuration, ensuring accurate and stable electrical control of ignition, fan operation, temperature regulation, pump control, and system safety circuits.
A faulty PCB is one of the most common causes of boiler lockouts, irregular ignition, or complete power failure—replacing it with an official Glowworm part restores safe and reliable boiler operation.
