What Uart ERROR COMMUNICATION means on a GE refrigerator

The Uart ERROR COMMUNICATION code on GE refrigerators is a diagnostic artifact rather than a true fault condition. UART stands for Universal Asynchronous Receiver-Transmitter, which is a serial communication protocol used internally between control boards and various subsystems within the refrigerator. During certain diagnostic test modes, the system runs checks across all communication channels, and this particular UART channel check may return a flag even when no actual communication failure is present in normal operation.

Because this error is classified as not applicable, it carries no real-world diagnostic weight. The flag does not correspond to a malfunctioning component, a wiring fault, or a failed control board under normal circumstances. It is a byproduct of the diagnostic routine itself and is expected to appear in certain test sequences without indicating any underlying problem with the refrigerator's communication network.

No corrective action is required when this code appears. Technicians running diagnostic tests on affected GE refrigerator models should note the code and move on without attempting component replacement or wiring inspection. Attempting repairs in response to this code would be unnecessary and could introduce new issues into a system that is otherwise functioning correctly. The refrigerator can be returned to normal operation without any intervention.

Common causes of Uart ERROR COMMUNICATION

  1. 01

    Diagnostic test routine artifact

    Wiring / connection

    This code appears as a byproduct of running the refrigerator's built-in diagnostic mode. It is not triggered by any real component failure and should be disregarded.

  2. 02

    Test mode UART channel flag

    Wiring / connection

    The UART communication check within the diagnostic sequence may flag this channel even when all internal communication between control boards is functioning normally. It reflects the test behavior, not an actual fault.

  3. 03

    Misinterpretation of diagnostic output

    Wiring / connection

    A technician or homeowner reviewing diagnostic results may mistake this code for a real error. Reviewing the full diagnostic output in context confirms this code has no actionable meaning.

Frequently asked questions about Uart ERROR COMMUNICATION

What does Uart ERROR COMMUNICATION mean on a GE refrigerator?
This code refers to a UART (Universal Asynchronous Receiver-Transmitter) communication flag that appears only during diagnostic testing on GE refrigerators. It is classified as not applicable, meaning it does not indicate a real fault or component failure. No repair is needed when this code is detected. Technicians should ignore it and continue with other diagnostic steps if necessary.
How do I fix the Uart ERROR COMMUNICATION code on my GE refrigerator?
No fix is required for this code. It is not associated with any actual malfunction in the refrigerator's components or wiring. If it appeared during a diagnostic test, simply proceed without taking any corrective action.
Is the Uart ERROR COMMUNICATION code a safety concern on a GE refrigerator?
No, this code presents no safety concern. It is a non-applicable diagnostic flag and does not indicate any electrical hazard, cooling failure, or risk to food safety. Your refrigerator can continue operating normally.
Will resetting my GE refrigerator clear the Uart ERROR COMMUNICATION code?
A reset is not necessary for this code since it carries no real fault status. The code is only relevant within a diagnostic test sequence and does not persist as an active error affecting the refrigerator's normal operation.
How much will it cost to repair the Uart ERROR COMMUNICATION error on a GE refrigerator?
There is no repair cost associated with this code because no repair is needed. It is a diagnostic test artifact and does not require any parts replacement or service work. If a technician has already been called, the visit cost would depend on local service rates, typically ranging from $75 to $150 for a diagnostic call, but no additional parts or labor should be needed for this specific code.
