If the food processor shuts off while it is running:
The food processor may be overheated. If the motor exceeds
a certain temperature, it will automatically shut off to
prevent damage. This should be an extremely rare
occurrence. If it happens, press the Off Button and wait
15 minutes for the food processor to cool before resuming.
If the food processor still refuses to run, wait an additional
15 minutes for the food processor to cool.
