Old Glowworm ignition keeps firing but boiler doesn't fireup
- Thread starter oldmac
- Start date
PCB is not detecting pilot, no flame rectification occuring, therefore won't let gas valve open.
Check pilot size and condition. Check sensor/probe. Check wire connecting it to pcb.
If all these ok then points to a pcb fault
