Ceramic Cooker & Induction Cooker - Why Is There Still Sound/Noise From The Cooker After Power Off?

The sound/noise is caused by the internal fan of the cooker. After you've powered off your cooker, because your cooker is still hot, the fan will still be working to cool down the cooker. It will auto switch off after it has done cooling the cooker off. Please do not unplug the plug from the socket when you hear the fan; it is normal.
