Samsung's refrigerator models make temperature selection simple by providing two separate buttons: one to control the refrigerator, and one to control the freezer temperature. Using these buttons, you can change the temperature for each part of your refrigerator unit separately. According to the U.S. Food and Drug Administration, you should keep your fridge temperature at or below 40 degrees Fahrenheit (4 degrees Celsius). Your freezer should stay at 0 degrees Fahrenheit (-18 degrees Celsius).
Look at the control panel on your Samsung refrigerator. It is located on the front of the unit, above the ice maker, if your model has one.
Note the separate buttons marked Freezer and Fridge. The Freezer button will be on the lower left part of the control panel, while the Fridge button will be on the lower right.
Press the Fridge button to switch the temperature between the presets available in your refrigerator's computer. Depending on the model of your Samsung fridge, you may see a graphic that displays the temperature range from cold to coldest. You may also see individual temperature values show up in numeric form on the control panel.
Press the Freezer button to switch temperature presets for your freezer. Just like with the fridge, your model of refrigerator will determine whether your temperature adjustments are displayed graphically or numerically.
Press and hold either the Freezer or Fridge buttons for three seconds to use Power Cool in either section of your fridge. For example, after you have first installed your refrigerator, you may want to use Power Cool to more quickly get your Samsung refrigerator to proper operating temperature.
