Is your Samsung refrigerator displaying an error code? Newer style Samsung refrigerators have built in diagnostic systems. If your refrigerator finds, sees, or detects a fault or error in the system, it will show an error or fault code. The error code will display where the usual numbers are on the display screen. When an error code is displayed, your refrigerator is telling you a specific fault.
Note: There are many different model numbers of Samsung refrigerators with digital displays so if you see an error code, write down what is flashing or displaying. Don’t pull the power from the fridge if it shows an error code. If you pull the power plug it will erase the fault code.
