Operational Noises - Frigidaire FPIC3695MSA Use & Care Manual

Power Sharing
(continued)
To get the highest power output from your cooking zones,
cook with only one cookware per heating section. If you
need to use most of your cooking zones at once, start your
cooking process on only one cooking zone within the heating
section and then add your second cookware on the second
cooking zone when the first one has already reached its
cooking temperature.
Remember to select the power setting last for the cooking
zone you want to maintain at full power or set the altered
power to where you want it.

Operational Noises
The electronics generating the induction fields 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:
o Most induction-ready cookware are made of several
layers of materials. An encapsulated steel layer is usually
used to harness the induction field and transform it into
heat, which is then transferred to the other materials by
radiant energy. The induction field 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 cookware may also vibrate. We recommend
using heavy weight quality cookware.
Cookware with warped bottoms can vibrate on the
ceramic glass surface at high power settings.
_ The power output of your induction
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.
