The usual causes are dirty or cracked flame rod, failed uv scanner, poor earth on the flame sensing circuit, incorrect air/fuel ratio. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Flame signal measurement in microamps; Earth continuity test; Combustion analysis through the firing range; Gas pressure under load. The readings are recorded so the repair decision is based on data.
Can I keep using the system in the meantime?
No — isolate the plant and call 069 268 0988. Running it in this condition risks further damage or an unsafe situation.
Do you attend this fault in Bryanston?
