Why does the One Top make noises when cooking? There are a variety of reasons why your Tasty One Top may make certain types of sounds or noise. The surface elements on an induction cooktop heat pots by using an electromagnetic field below the glass cooktops surface. For this reason you may often hear the clicking, humming or buzzing of the heating element electronics at certain power settings. If you hear any type of cooking noise your cooling fan could be turned on, you may be cooking at high power levels, your pot may be empty or cold, or the One Top may be faulty. In most cases, some cooking noise is perfectly normal in induction cooking. Cooling Fan The cooling fan turns on shortly after cooking starts. The fan will typically run when One Top is in use, cooling down or even after powering off, if cooling is required. The cooling fan may also emit a “humming” noise when it turns on to cool the induction elements. Cookware Different types of cookware may produce cooking noise. Heavier pans like enameled cast iron produce less noise than a lighter pans like multi-ply stainless steel. The size of the cookware and the amount of its contents can also contribute to the sound level. Depending on the type of cookware you use, there may also be a slight “buzz” or electrical cackling when cooking at high power levels, or if the pan’s contents are cold. This noise may sound like a buzz of a bee. It is normal, and as the cookware heats or you reduce the power level, the sound will decrease. If you suspect your Cooktop is faulty, we advise you to contact customer support.
