Built-in hobs look simple from above, but their ignition, burners and gas connections are integrated into a fixed kitchen installation. For that reason, it is useful to separate safe basic checks from work that should be left to a technician.
One burner will not light
If only one burner is affected, first make sure the burner cap is seated correctly and the area is clean and dry according to the manufacturer’s instructions. If the issue continues, the ignition point, burner assembly or another serviceable component may need inspection.
The ignition keeps clicking
Moisture or residue around the ignition area can sometimes contribute to repeated clicking, but continuous or recurring clicking should not be ignored. Turn the appliance off and allow cleaned areas to dry. If the symptom persists, arrange professional inspection.
The flame looks different from usual
A sudden change in flame pattern, stability or strength can have several causes. Do not attempt to adjust internal gas settings yourself. Stop using a burner that appears unsafe and have the hob inspected.
Several burners are affected at once
When multiple burners show the same problem, the cause may be broader than one burner head. Because gas supply and internal components can be involved, technician assessment is the safer next step.
Provide model information when requesting service
Built-in hobs vary widely. Sharing the brand, approximate model, number of burners and exact symptom can help the service provider understand the likely scope before visiting.
Important safety note
These guides provide general maintenance information and are not a substitute for on-site diagnosis. Do not dismantle gas lines, regulators or internal gas controls. If you suspect a leak or immediate danger, stop using the appliance and seek appropriate emergency or qualified service assistance.
