Symptoms
- Clicking noise continues after the flame is already lit
- Clicking gets worse if something boils over
- Sound comes from near the base of the burner
- Flame itself looks and burns normally
Likely causes
- CommonLiquid boiling over onto the igniterMoisture on the igniter can cause it to keep sparking even with a flame present.
- PossibleGrease or residue bridging the igniter contactsBuildup can act like moisture and trigger extra sparking.
- PossibleFaulty ignition switch under that knobA worn switch can intermittently signal for a spark even with the burner lit.
- Less commonSpark module malfunctionRarely, the electronic module misfires even without a physical trigger.
What to do
- If something is actively boiling over, lower the flame or move the pot to stop new spills reaching the igniter.
- After the burner cools, clean the igniter and burner base thoroughly and let them dry completely.
- Check that the burner cap is seated flat and centered.
- Cook a test batch and watch whether clicking still happens once everything is dry and clean.
- If it continues with a clean, dry burner, note whether it happens with every burner or just one.
- A single problem burner points to that knob's switch; all burners clicking points to the shared spark module.
