The Power Freeze feature on Samsung refrigerators speeds up the ice-making process and reduces the time for the ice maker to make a tray of ice. It can also speed up the time needed to freeze products in the freezer. When activated, both the compressor and the freezer fan will run for up to 10 hours continuously. If the ice bucket fills in less than 10 hours, Power Freeze stops automatically. The Power Freeze function can be helpful if you need to quickly freeze items that spoil easily or if the temperature in the freezer has warmed dramatically, for example, if the door was left open. To start the Power Freeze function, press the Power Freeze button. To cancel, re-hold the Freezer button for 3 seconds or just touch (push) the Power Freeze button again. If you need to freeze a large amount of food, activate the Power Freeze function at least 20 hours before. When you use Power Freeze, the energy consumption of the refrigerator will increase. Remember to turn it off when you dont need it and return the freezer to your original temperature setting.
