How to Fix / Troubleshooting
Safety: Turn off gas and power before accessing burner or ignition components.
Steps:
- Inspect ignition electrode and cable: Check for cracks, carbon buildup, or loose connections. Clean and reseat as needed.
- Check earth connection: Ensure the appliance is properly earthed and that earth wires are secure.
- Observe ignition attempt: With the cover in place, listen for the clicking of the igniter when a demand is present. No clicking suggests an ignition control issue.
Note: If the fan runs but there is no spark or gas valve operation, a technician should test the PCB and gas valve circuits.
