The supper button on the fridge can be used to activate the “supercool” and “superfreeze” modes for the fridge and freezer compartments, respectively. These modes will come in handy while storing a large amount of food or drinks to chill them quickly. Once you press the super button, it will bring down the temperature of the fridge from the default 40-degree Fahrenheit (approximately) to about 34-degree Fahrenheit. The unit will remain this way for a couple of hours before going back to the original temperature. Similarly, the temperature of the freezer goes down from 0-degree Fahrenheit to -8-degree Fahrenheit for 6 hours before getting reset.  Another thing to note here is that the coldest setting of the freezer or fridge section will always be the highest number displayed on the temperature dial. And this is applicable to all types of models.
