Using My Refrigerator If an Er dH, Er d1, Er d2, Er d, Er H1, or Er

</dt>
<dd>

<span role="img" aria-label="Answer">A.</span> Your refrigerator may
operate normally once the ice on the cooling plate is removed, but
the error may return over time. <br/>To temporarily resolve the
issue, remove all food from your refrigerator and place dry towels
on the floor in front of the doors. <br/>Then, unplug the power
cord from the wall outlet and leave the doors open for at least 12
hours.<br/>
However, frequent errors can decrease cooling performance and affect
food quality, so we recommend contacting LG Customer Support for
assistance.
