Hi Dejavoo, thank you for your question and interest in Model:NIT5068UC. Per the Use and Care Manual for this Cooktop: Noises may be generated while using the cooktop depending on the base material of the cookware. These noises are a normal part of induction technology. They do not indicate a defect. Possible noises: A low humming noise like the one a transformer makes: Occurs when cooking at a high heat setting. The noise disappears or becomes quieter when the heat setting is reduced. Low whistling noise: Occurs when the cookware is empty. This noise disappears when water or food is added to the cookware. Crackling: Occurs when using cookware made from different layers of material or when using cookware of different sizes and different materials at the same time. The volume of the noise can vary depending on the quantity of food being cooked or the cooking method. High-pitched whistling noises: Can occur when two elements are used on the highest heat setting at the same time. The whistling noises disappear or become quieter when the heat setting is reduced. Fan noise: The cooktop is equipped with a fan that switches on automatically at high temperatures. The fan may continue to run even after you have switched off the cooktop if the temperature detected is still too high.
