Do I need special Cookware to use the One Top? Yes. Induction-compatible cookware is required when using the One Top. The cooktop does not generate heat until you place proper cookware on the cooking surface. If proper cookware is not used, the 8th LED on the front of the One Top will flash and your pan may not heat properly. The flashing LED means no pot was detected on the cooktop. You will need to place an induction-compatible pot or pan on the cooktop to continue cooking. Induction cookware guidelines Use the following guidelines when choosing cookware to use with the One Top: Cookware should be made of cast iron, iron, steel, stainless steel, enameled steel, enameled iron, or cookware with an induction base. Cookware made of magnetic material is induction-compatible. Use cookware with a flat bottom; warped or curved cookware will not heat evenly. Cookware must fully contact the surface of the cooking element. Induction disks are not recommended. Base of cookware should be 6 to 11 inches in diameter Note: The cooktop will not operate if you place a very small steel or iron utensil (smaller than the diameter of the cooktop) on the cooking surface when it is on—items such as steel spatulas, cooking spoons, knives, and other small utensils. How can I test my Cookware for compatibility? The majority of pans used today are induction safe. In most cases, you can test for compatibility right in your own kitchen. One quick and easy way to test for induction-compatibility is to use a basic kitchen magnet. Place the magnet on both the inside and outside bottom base of the cookware to see if it will stick. If the magnet sticks, then you know your pan is induction-compatible. Note: To learn more about induction cooking, visit What is Induction Cooking? Why is my cookware not heating properly? On almost all counts, induction cooking on the One Top should be faster and more efficient than most gas or electric stove tops. The amount of time it takes to heat a pot of water depends on the size and shape of the pot or pan, the amount of food or water, and many other variables. If you continue to have issues heating your pan, we recommend using cookware with a flat bottom; warped or curved cookware will not heat evenly, and would take longer to heat your pot. If you suspect your Cooktop is faulty, we advise you to contact customer support. Certain types of cookware may also cause 1-5 degree fluctuations in surface temperature readings. For the most precise temperatures, we recommend using the temperature probe when cooking.
