Surface burner on gas cooktop will not ignite; you hear clicking but no flame.

Safety first: Turn burner knobs OFF and ensure no gas smell is present before working. Disconnect power if removing burner parts near wiring.

Steps to check:

• Check cap alignment: Remove and reseat the burner cap so it sits flat and centered on the base.
• Clean burner ports: Use a soft brush or a wooden toothpick to clear debris from the small gas ports around the burner head. Do not use metal objects that can enlarge the holes.
• Inspect electrode: Ensure the spark electrode is clean, not cracked, and positioned close to the burner cap. Clean with a non-abrasive pad if dirty.
• Swap parts: Swap the burner cap and head with a working burner. If the problem follows the parts, replace the burner head. If it stays at the same location, the issue may be the valve or spark module and should be checked by a technician.
