What should I do if the temperature display is blinking on my Samsung refrigerator?

The Freezer or Fridge temp indicator will blink when the temperature in the compartment goes up dramatically, and will stop blinking once the temperature returns to normal. If the blinking continues, try unplugging the appliance, waiting approximately 10 minutes, and then plugging it back in. If there is a communication error between the Display and Main Controller, the display may blink 'PC-Er' and the refrigerator will beep — if this continues for a long period, contact a Samsung Electronics Service Center.
