Quick answer
84C on a Samsung refrigerator means compressor lock. If it persists, the next step is to request service.
Model compatibility: Samsung reuses codes across series and model years, so 84C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

What this code means
