Troubleshooting
Sounds and Noises
Symptom
Noise is heard during
heating.
The level of the noise
from the appliance
increases and
decreases.
After the main power
switch is turned off,
noise from the fan is
heard.
Heat Power
Symptom
The heating power is
weaker.
When multiple
cooking zones are
used together,
■ The heating power
decreases.
■ The power indicator
automatically
decreases.
■ The power level can
not be increased.
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.
Possible cause
Overheating Prevention Function
If the base of the cookware overheats, the heating power
will automatically reduce. The power indication will remain
the same. The power returns to normal after the cookware
cools down.
Unsuitable cookware, e.g. ceramic and earthenware pans,
are used.
Do not use ceramic and earthenware pans even if they
are for induction heating as they are not efficient. (See
pages 15-16)
The power level is automatically regulated so that overall
power consumption does not exceed the limit.
The power indicator for a cooking zone may decrease on
its own. Even after touching the
'+' (KY-R644CL) to adjust power level, it may
not increase the power level and the appliance will beep.
