Gas cooktop burner ignites but keeps clicking even after the flame is established.

Safety first: Turn off the burner and disconnect power to the cooktop.

• Dry electrodes: If the issue started after a spill, remove burner caps and heads and gently dry the spark electrodes with a soft cloth. Allow the cooktop to air dry for several hours.
• Clean electrodes: Remove grease buildup from the ceramic and metal tip of each electrode using a non-abrasive pad.
• Check alignment: Ensure the electrode tip is close to the burner cap edge where the flame appears.
• Inspect switches: Remove knobs and check that the ignition switches return to the off position when knobs are released. Replace any switch that feels sticky or remains engaged.
• Test operation: Restore power and gas, then test each burner. If clicking persists on one burner only, focus on that burner’s switch and electrode.
