Why did my Burner turn white on glass top stove?

When a burner on a glass top stove turns white, it typically indicates that the surface has experienced overheating or damage. This discoloration can be caused by cooking at excessively high temperatures or by spills that have burned onto the surface. Additionally, the white appearance might be a result of mineral deposits from hard water if the stove isn't cleaned regularly. To prevent further issues, it's important to clean the surface properly and avoid high heat settings.
