Operational noises
The electronics generating the induction fi elds are
pretty much noiseless but they do produce heat
at high power level. A soft-sounding cooling fan
activates when the unit is running multiple cooking
zones at once or when a cooking zone is set at very
high power settings.
The buzzing sound you could hear from your cooktop
is not coming from the electronics but from the
cookware you are using. Here are some causes of
this noise:
• Most induction-ready cookware are made of several
layers of materials. An encapsulated steel layer is
usually used to harness the induction fi eld and
transform it into heat, which is then transferred to
the other materials by radiant energy. The induction
fi eld will cause the steel layer to vibrate against
the other materials in which it is encapsulated.
This is the most common cause of noise from the
induction process. This buzzing only happens at
the higher power level settings. Note that high
quality cookware manufacturers weld this steel
layer in place which lowers or cancel this noise.
• Light
weight
We recommend using heavy weight quality
cookware.
• Cookware with warped bottoms can vibrate on the
ceramic glass surface at high power settings.
•
cooktop is capable of warping an empty pan. Never
use the higher power settings on an empty pan.
Even the highest quality cookware is vulnerable to
warping.
• Riveted handles on cookware can also cause
buzzing sounds from the vibrations.
• Solid cast iron and enamelware cookware should
not emit any noise. Top quality cookware made of
several layers should also be relatively quiet.
