Some pans
make
crackling or
clicking
noises.
This may be
caused by the
construction of
your cookware
(layers of different
metals
vibrating
differently).
This is normal for
cookware and
does not indicate a fault.
The induction
hob makes a
low humming
noise when
used on
a high heat
setting.
This is caused by
the technology
of induction
cooking.
This is normal, but the
noise should quieten
down or disappear
completely when you
decrease the heat setting.
Fan noise
coming from
the induction
hob.
A cooling fan built
into your
induction hob has
come on to
prevent the
electronics from
overheating. It
may continue to
run even after
you’ve turned the
induction hob off.
This is normal and needs
no action. Do not switch
the power to the induction
hob off at the wall while
the fan is running.
