Gas hob repairs in Johannesburg: burner and ignition faults
If your built-in gas hob sparks continuously, one burner fails to light or a control no longer shuts off properly, contact us about an appropriate Johannesburg assessment.

The correct repair starts with the fault
A built-in hob is fitted differently from a freestanding cooker. Its burner components are reached from above, while control parts and gas connections may lie below a worktop. Before anyone disturbs cabinetry, we need to understand which part of the cooking process has failed and whether it is safe to continue using the appliance.
Burner sparking without catching flame
A visible spark does not prove that the burner has correct flame conditions or supply. Mispositioned caps, dirty assemblies and ignition alignment can be relevant; the installed model determines the inspection. Tell us whether one ring or every ring is affected and whether the trouble follows cleaning or a period of non-use.
Ignition clicking continues with the knobs off
On electrically ignited hobs, moisture around switches or an electrical fault can cause repeated sparking. The diagnosis differs from a knob that sparks normally during selection. Stop using equipment that cannot be controlled safely and request an appropriate assessment rather than dismantling the ignition wiring.
Burner lights but is extinguished on release
Many hobs use flame-supervision components that require a stable flame condition. If it dies when you release the knob, the sensing and control arrangement needs proper testing. Bypassing the interlock or wedging the knob open is unsafe and not a repair option.
Heat weak on one particular ring
A simmer burner and a high-output ring will not have identical flames. We ask whether the abnormality is new, whether the ring behaves differently at low output and whether the cap is seated correctly. A replacement injector must match the exact approved appliance and gas type; drilling or enlarging jets is unacceptable.
Built-in gas hob beside an electric oven
Mixed installations can involve both electrical and gas considerations, with limited space beneath the counter. Let us know if a new oven or cabinet has changed access around the hob. We plan a safe method of assessment without advising you to pull out appliances or loosen gas connections.
Damage to control knobs and valves
A cracked removable knob and a seized gas valve are different problems. Forcing a resistant valve can worsen damage. We need to know whether the gas turns fully off and whether the fault is confined to one control. A potentially unsafe shut-off condition needs prompt professional attention.
Flame changes, soot or an unusual smell
These can indicate serious operating concerns. Stop using the affected hob, avoid ignition sources if unburned gas is suspected and seek emergency assistance when appropriate. Combustion quality cannot be declared safe from a photograph or by cleaning away residue.
Arrange a Johannesburg hob assessment
Give the suburb, hob model, burner layout and the exact symptoms. Mention built-in access constraints or security arrangements. We confirm coverage, the appropriate scope of work and appointment availability before any attendance.
Questions about this repair
Can I replace a gas hob burner injector myself?
Do not alter gas-metering parts; use the manufacturer-approved component and registered practitioner as applicable.
Does sparking on several rings mean the hob is faulty?
Not always; some systems spark multiple rings by design.
Is a freestanding gas cooker the same as a built-in hob?
No. Component access and installation arrangements differ, so tell us which type you own.
