How do I repair my gas stove burner?

Hi Lynn, Remove the burner and soak the sealed burner base in vinegar or warm water and use a stiff brush to remove any debris. Finally, clean any remaining debris out of the burner holes with a toothpick, sewing needle or compressed air. Reinstall the burner, cover and the grill, and try igniting the burner once more. The entire ring will likely burn clean and evenly.

causes for uneven flames:

• Flame may be uneven where the electrode (igniter) is located.
• Some burners intentionally have an uneven flame, like a center oval burner. One side has shorter flames than the other, which decreases the likelihood it will go out because of a closed door, etc.
• The Power Boil burner has an irregular teeth pattern. The reason is that the burner is optimized to give both good high "Power Boil" heat performance as well as provide good performance and flame size at other settings.
• A Tri-ring burner has a burner head with three rings which may contribute to the appearance of an uneven flame.
• Additionally, flame problems can occur if the wrong burner head is being used or if the burner head is not sitting flat on the burner base.
• Burner slots on the side of the burner may be clogged. Remove the burners for cleaning. See the Care and Cleaning section of your Owner's Manual.
