What the Uart ERROR COMMUNICATION error code actually means

Your Samsung refrigerator has logged a communication event between its internal control boards, but Samsung has determined that this particular code does not represent an actual problem or malfunction. It is essentially a system note rather than a true error, meaning your refrigerator is not experiencing a fault that requires repair. If your fridge is cooling properly and functioning normally, you can safely disregard this code.

Questions people ask about Uart ERROR COMMUNICATION

What does Uart ERROR COMMUNICATION mean on a Samsung refrigerator?
This code indicates a UART serial communication event was detected and logged by the Samsung refrigerator's control board. Samsung classifies this code as not applicable to any real fault condition. It does not correspond to a failed part or a system problem, and no repair is needed.
Can I still use my refrigerator with Uart ERROR COMMUNICATION active?
Yes, you can continue using the refrigerator normally. This code does not indicate a cooling failure, a safety hazard, or a damaged component. Monitor the refrigerator to confirm temperatures remain stable and watch for any additional error codes that carry actual fault conditions.
Why does Uart ERROR COMMUNICATION keep showing up on my Samsung refrigerator's display?
This code most commonly surfaces during a diagnostic test cycle or after a power reset. Because Samsung designates it as a non-applicable code, repeated appearances do not signal a worsening problem. If the code is showing outside of diagnostic mode and you cannot clear it, check whether another error code is also active, as that secondary code may be the actual issue requiring attention.
How do I fix Uart ERROR COMMUNICATION on a Samsung refrigerator?
No fix is required for this code. Samsung's own service documentation states this error is not applicable, and if it appears during diagnostic testing, it should be ignored. Verify your refrigerator is cooling correctly and check for any other error codes that may be active alongside this one.
How much does it cost to fix Uart ERROR COMMUNICATION on a Samsung refrigerator?
The cost is zero. This code requires no repair, no replacement parts, and no service visit specifically for this code. If a technician visits and this is the only code present, no corrective work should be billed for it. If other error codes appear alongside it, those separate codes may carry their own repair costs.
