Gas burner clicks but does not light, or lights only after several attempts

Safety first: Turn the burner OFF and allow components to cool. Close the gas supply if removing burner parts.

• Check gas supply: Ensure the main gas valve is fully open and that other gas appliances work normally.
• Clean burner: Remove the burner cap and head. Clean all ports with a soft brush and a wooden toothpick (never use hard metal that can enlarge holes). Ensure the central opening is clear.
• Align cap: Refit the burner head and cap correctly on the base so they sit flat and centered over the electrode.
• Inspect electrode: Check that the spark electrode is not cracked and is positioned close (2–4 mm) to the burner edge. Clean it gently with a non-abrasive pad.
• Test ignition: Restore gas and ignite. If the burner still struggles to light, have a technician check gas pressure and regulator sizing for your Glem Gas model.
