Yes, yes and yes. The fan is underneath and in the unit.
I can say that if the pan is the wrong kind, it won't even turn on and warm up. The pan has to be on it for it to turn on. If you lift the pan up, it will beep for so many seconds and then turn off. I'm not sure about the fan but believe it to be FCC approved. When you set up the temperature you want, it won't turn on till you press the power spot.
If there is no metallic pan the cutoff safety is still engaged, so yes. Also it does have an internal cooling fan? It also is FFC and ETC approved.
Yes it does have an auto cut off It shuts off after 1 hour of cooking unless you set the timer.
Also if you lift the pan off the unit it will shut off and give an "E1" error code in the display.
And it does have an internal fan that you can feel running when the unit is on.
Yes, it will display E1 and cur off if you remove the pan or try to turn it on without a MAGNETIC pan on it. The FCC id# is on the box and in the manual. It is suggested not to place it beside things it ciuld interfere with.
