Before you reset: Samsung asks owners not to unplug the fridge or press buttons to clear a code unless its own steps say to, because that can erase information a technician uses to diagnose it.
Likely causes

- Problem with the compressor drive or control
- Power supply problems
Safe checks you can do
Safety: Owner checks only. Do not open the sealed refrigerant system, remove electrical covers, or bypass parts. Compressor and refrigerant work needs a licensed technician.
- Confirm the fridge is on its own outlet with no extension cord or power strip.
- Move perishables to a cooler and watch temperatures with a thermometer.
- Do not try to service the compressor or anything in the sealed system yourself.
When to call a pro
- Any time you see this code
- The fridge or freezer is warming up
