LG refrigerator error codes

Search this source-linked list using the exact display. Open a matching record for its plain-language meaning and manufacturer reference, then confirm the interpretation in your model manual.

Refrigerator codes can refer to a fan or defrost-sensing condition, but they do not reveal the compartment temperature or whether food is safe. Samsung specifically says not to unplug or clear its error display unless directed. The article scope may not cover every LG refrigerator model or revision.

Before you act

Code meanings are not universal.

Refrigerators: If cooling is impaired, use the manufacturer's support path and an authoritative food-safety source. UnknownCodes cannot assess stored food, temperature history, or a refrigerator's condition remotely.

These summaries describe the manufacturer's published explanation. They are not a remote diagnosis and do not establish that a specific component has failed.
