Normal operating noises of the cooktop
Induction technology is based on the creation of
electromagnetic fields. They may generate heat directly
on the bottom of the cookware. Pots and pans may
cause a variety of noises or vibrations depending on the
way they've been manufactured. These noises are
described as follows:
Low humming (like a transformer)
This noise is produced when cooking at a high heat
level. It is based on the amount of energy transferred
from the cooktop to the cookware. The noise ceases or
quiets down when the heat level is reduced.
Quiet whistling
This noise is produced when the cooking vessel is
empty, tt ceases once water or food is placed in the
vessel.
Crackling
This noise occurs with cookware comprised of various
materials layered one upon the other. It's caused by the
vibrations of the surfaces where different materials meet.
The noise occurs on the cookware and can vary
depending on the amount and method of preparation of
the food.
Loud whistling
This noise occurs with cookware comprised of different
materials layered one upon the other, and when they are
additionally used at maximum output and also on two
cooking zones. The noise ceases or quiets down when
the heat level is reduced.
Fan noises
For proper operation of the electronic system, it is
necessary to regulate the temperature of the cooktop.
For this purpose, the cooktop is equipped with a cooling
fan, which is activated to reduce and regulate the
temperature of the electronic system. The fan may also
continue to run after the appliance is turned off if the
detected temperature of the cooktop is still too hot after
turning it off.
The noises described are a normal element of the
described induction technology and shouldn't be
regarded as defects.
