Most food processors have a automatic thermal overload switch, a safety features that is supposed to stop the motor if it overheats. Overheating can
occur if the motor stalls under a heavy load, or if a piece of food becomes jammed between the blade or disk.
This saves the abnormal expense of having to replace the motor if it went bad. But nowadays, manufacturers usually replace the entire machine provided it's still under warranty.
In my case where I've had my Cuisinart DLC-7Pro, for almost 20 years, if it every goes bad, I'd just replace it with another Cuisinart.
