Gas burner will not ignite or takes a long time to light, but other burners work normally.

Safety first: Turn off the burner control and ensure no gas is flowing while you work. Do not use sharp metal objects that could damage parts.

User steps:

• Remove the burner cap and head from the affected burner.
• Clean the burner cap and ports with warm soapy water and a soft brush; ensure all flame holes are clear.
• Dry thoroughly and refit the burner head and cap, ensuring they sit flat and correctly located.
• Check that the spark electrode tip is clean and positioned close to the burner (2–4 mm gap).
• Try lighting again; listen for a strong clicking and look for a visible spark.

Technician steps (if still faulty):

• Inspect the electrode for cracks or damage and replace if necessary.
• Check the ignition lead from the spark generator to this electrode for continuity and insulation damage.
