If your Samsung refrigerator appears dead or is not running and the display and buttons are unresponsive, start by checking the dispenser control board and the user control and display board, since failed control boards are the most common causes when the refrigerator display not working or the refrigerator control panel not working. Next verify incoming power: make sure the plug is fully seated in a regular outlet, the outlet is giving power and no breakers or fuses are tripped, and avoid using a ground fault outlet for a fridge. Also check the wire harness for loose or damaged connectors, and try a simple power reset after a surge by unplugging the unit or switching the breaker off for a few minutes. Replacing the main control board is rarely needed, so test the more common parts first and inspect boards for burn marks before swapping them.

Ensure plug is tightly pushed into a regular electrical outlet and the outlet is supplying power. Using a ground fault outlet for a refrigerator is not recommended. Confirm that no circuit breakers have tripped or fuses have blown.

03 - Samsung Refrigerator User Control and Display Board
If the refrigerator display appears completely dead, it's possible the user control and display board has failed. You should inspect the board for any burn marks and replace it if it appears damaged.
The wires from the control panel to the control board may be loose or have become disconnected. Make sure the wire harness connectors are tight. A damaged wire harness will need to be replaced.

05 - Power reset
After a power surge or power outage, refrigerator operation could be temporarily affected. Full operation can sometimes be restored through a power reset by either unplugging the appliance's power cord for a few minutes and then plugging it back in or switching off the circuit breaker for the refrigerator then switching it back on.

06 - Samsung Refrigerator Control Board
If nothing is working on the refrigerator, it's likely the control board is defective. However, this is almost never the cause. Before replacing the main control board, test all of more commonly defective parts. If none of the other components are defective, consider replacing the control board.
