Some cookers use a common ignition arrangement. Pressing one button may create sparks at several positions even though only the intended burner is being supplied through its control.
What the observation means
The visible sparking pattern is therefore not enough to identify a fault at every burner. Follow the appliance's normal ignition sequence and keep gas and electrical observations separate.
A useful next step
Report which burner fails to establish a flame and whether the common button responds. Do not touch electrodes while operating ignition or remove burner parts when hot. Persistent unintended clicking or a gas smell requires the appropriate stop-use response and assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
