Kya Sand · Same-day
Gas Boiler Not Igniting in Kya Sand
The boiler attempts to start, clicks or purges, then locks out without lighting. This page covers how we diagnose and repair it on boilers in Kya Sand.
This fault is normally treated as same-day work because the site has effectively lost hot water, steam or safe operation.
Kya Sand is a high-value residential pocket of Randburg, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. 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
Frequently asked questions
What causes gas boiler not igniting?
The usual causes are failed ignition electrode or transformer, no gas supply or closed valve, gas solenoid or valve failure, air pressure switch not proving. Which one it is can only be confirmed by measurement, not by symptom alone.
How do you diagnose it?
Electrode gap and spark test; Gas pressure measurement at the train; Air proving switch continuity test; Flue and condensate path inspection. 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 Kya Sand?
Yes. Technicians work out of the central Johannesburg base, which keeps travel time short for northern-suburb call-outs. Kya Sand falls inside our core northern-suburb route, so response is normally same-day for loss-of-hot-water call-outs.
