Noises
When using an induction heater, the following noises can occur in the pan, de-
pending on what it is made of and how it is constructed.
~ Higher power settings may cause a buzz. This will decrease or cease alto-
gether when the power setting is reduced.
~ If the pan is base is made of layers of different materials (e.g. a sandwiched
base), a cracking sound may be heard.
~ Whistling might occur if linked burners (see “ Booster function” ) are being
used on the highest setting at the same time, and the pans have bases made of
layers of
different materials.
~ You may hear a clicking sound from the electronic switches, especially on lower
settings.
~ The hob has a cooling fan to help extend the life of the electronics. When the
hob is being used at high levels for a long period of time, this will come on and
you will hear a whirring sound. The fan may continue to run after the hob has
been switched off.
