The burner lights then loses flame within seconds and locks out. This page covers how we diagnose and repair it on boilers in Craighall Park.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Craighall Park sits within the Rosebank belt, with larger stands, long hot water runs and frequent pool heating. Static pressure and dead-leg length are checked as part of any hot water complaint here. Sites with long, poorly insulated pipework lose more heat in distribution than most owners expect, which reads as a capacity problem at the outlet.

FAQs

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 Craighall Park?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Craighall Park visits carry heat pump and geyser spares together, since both are commonly installed on the same property.
