Important: Disconnect power or gas before any service procedure that requires access to internal components. These guides explain symptoms; they are not a substitute for safe technical diagnosis.
Moisture around the burner
Cleaning water, boil-overs or damp burner parts can temporarily conduct electricity and trigger continued sparking.
Burner cap and electrode alignment
A burner cap that is not seated correctly can distort the flame path and prevent reliable ignition.
Ignition switches and wiring
A stuck or shorted switch can keep the spark circuit energized even when the knob is no longer in the light position.
Spark module diagnosis
If electrodes, caps, switches and wiring are correct, the spark module may need testing.
Frequently asked questions
Allow components to air dry fully. Avoid aggressive heat that can damage finishes, wiring or seals.
Many ranges use a common spark module, so all electrodes may spark during ignition. Continued clicking after the flame is stable is the symptom to investigate.
If you smell gas, cannot shut a valve, or the flame is abnormal, turn the appliance off and contact the gas utility or emergency service as appropriate.
