Many Samsung freezer refrigerators have a digital temperature display inside of the appliance. If you leave the appliance doors open or place a large amount of hot food into the refrigerator, the temperature display may begin to blink. The display usually resets itself after a few minutes, but you may need to manually reset it.

Step 1
Unplug the refrigerator.
Step 2
Wait 10 minutes.
Step 3
Plug it back into the wall. The refrigerator is reset, and the display will stop blinking.
