Refrigerator · communication error

DISPLAYCO
MEANING

The display and main controller cannot communicate correctly.

LG requires inspection when CO recurs; the cause may be a temporary power disturbance or an internal communication fault.

SAFE FIRST STEPS

Only if safe, disconnect power for about five minutes and restart. If CO returns, monitor food temperature and request LG service; do not open the appliance.

Error codes can differ by model and series. Also check the exact model number and the matching LG manual.
