An induction hobe
makes several different sounds during use. For example, if one of the cooking plates is on low power, a snapping sound can be heard, while on high power it may instead emit a humming noise. The heating zones also have a cooling fan that prevents the electronics from becoming overheated. You will therefore also experience a rushing noise from the ventilator, which may be heard even after switching off the cooker. All these sounds are quite normal, but should not be so loud that they disturb you. If you experience more noise than described above, it is probably because the pans you use are not optimal for induction hobs.
Your cooking pans should ideally have a thick bottom of magnetic iron, but many manufacturers today use other materials. Saucepans made of 100% copper, aluminium or non-magnetic stainless steel unfortunately will not work on your induction hob because it uses magnetism. If your induction hob makes snapping or buzzing noises, it is a good idea to review your kitchen utensils and possibly replace some pots and pans.
You can easily test which of your pots or pans can be used with the induction hob. All you need is a simple magnet (such as a refrigerator magnet). Put the magnet against the bottom of your pan and if the magnet sticks, the pan will work on your induction hob. However, to get the absolute best effect with your induction hob, you should use cooking equipment with bottoms made of 100% iron.
