After cooking fan stays on never turns off. Waited hours and hours still running. Finally unplugged it. I Will hate to unplug it every time after using also, was disappointed that I bought the one without the dehydrate feature. Not sure about the convection aspect. Didn't seem to cook faster. It did, however, make pretty good broiled pork chops. Nicely browned and juicy. But I primarily wanted to save money by making homemade chicken 
 Jerky for my dog :( I wish it said somewhere that this model will not dehydrate.
