Gas burner clicks continuously even after flame is lit on LG gas range or cooktop.

Safety first: Turn off the burner. Avoid touching hot parts.

• Dry components: If the cooktop was recently cleaned or something boiled over, moisture may be causing continuous clicking. Turn off power and allow the cooktop to dry for several hours, or use a fan to speed drying.
• Check burner cap alignment: Ensure the burner caps are properly seated and centered on the burner bases. Misalignment can prevent proper flame sensing.
• Clean igniters: Gently clean the igniter tips and surrounding area to remove food or grease buildup.
• Inspect igniter: If the porcelain is cracked or the igniter is loose, replace the igniter electrode.
• Module replacement: If clicking persists on all burners even when dry and properly assembled, the spark module may be defective and require replacement.
