A low humming like a

A low whistling
Crackling
High pitched whistle
Fan noise
Induction heating technology is based on the creation of electromagnetic fields that
cause heat to be created directly on the pan base. Depending on the construction
of the cookware, certain noises or vibrations may be created, such as the following:
This occurs when cooking at a high power. The cause of this is the amount of
energy which is transmitted from the appliance to the cookware. This sound
disappears or becomes quieter when the power is turned down.
This occurs when the cookware is empty. This sound disappears when water or
food is added to the cookware.
This noise occurs when cookware is used which consists of layers of different
materials. The noise is caused by vibrations in the joint faces between the different
layers. This noise comes from the cookware. It may change depending on the
amount and type of food being cooked.
This noise occurs principally in cookware which consists of layers of different
materials when used at the highest heat setting and on two elements next to each
other. This whistling disappears or becomes quieter when the power is turned
down.
The electronics require a controlled temperature in order to function reliably. The
cooktop is therefore fitted with a fan which runs at various speeds according to the
temperature detected. The fan may also continue to run even after the cooktop has
been switched off if the temperature it detects is still too high.
The sounds described are a normal part of induction technology and do not indicate
a defect.
