Possible cause
Various sounds may be heard depending on the type of
cookware. You may feel a small vibration when you hold
the handle and the cookware may move slightly.
This is not a malfunction. Moving the cookware
slightly or replacing it may eliminate the sound.
If the cookware is removed during heating, a short
metallic sound may be heard.
It is the sound of the cooling fan inside the appliance.
The level of noise changes according to the power level
and the material of the cookware. When the power level
is increased, the fan will operate at high speed and
generate more noise.
While the inside of the appliance is still hot, the cooling
fan operates. When the appliance cools down, it will
automatically stop.
This is not a malfunction. This is a part of induction
heating technology. The noise is eliminated during
operation.
