          Follow the steps below to check whether your refrigerator is cooling
          properly.

<ul class="cause-list text">
          
<li>
            <strong>Touch and smell check:</strong> If storage containers feel
            cold to the touch and there is no strong food smell when you open
            the door, your refrigerator is working normally.
          </li>
          
<li>
            <strong>Condensation check:</strong> During the summer, if
            condensation forms on containers when warm air enters after opening
            the door, this is normal.

<h2 class="tit mainName">What to do if my refrigerator is not cooling</h2>
      
<div class="HowToStep">
        
<h3 class="name">Step 1. Lower the temperature setting</h3>
        <p class="text">
          If the temperature is set too high (around 5–6°C / 41–43°F), your
          refrigerator may not cool properly. <br/>
          Press the [Refrigerator Temperature] button on the display and set it
          between 1–3°C / 34–37°F.

<div class="HowToStep">
        
<h3 class="name">Step 2. Rearrange food and clear the air vents</h3>
        <p>
          If the refrigerator is overfilled or the air vents are blocked, cold
          air cannot circulate properly.
        </p>        
<ul class="cause-list text">
          
<li>
            Remove any items blocking the air vents inside the refrigerator.
          </li>
          
<li>
            Also organize items in the freezer. (In most refrigerators, cold air
            is generated in the freezer and flows into the refrigerator.<br/>
            If airflow in the freezer is restricted, your refrigerator may not
            cool properly.)
          </li>
        </ul>

Correct: Food organized to allow proper airflow.

<div class="HowToStep">
        
<h3 class="name">Step 3. Make sure the doors are fully closed</h3>
        <p>
          If a door is slightly open, warm outside air can enter, and your
          refrigerator may not cool properly.
        </p>        
<ul class="cause-list text">
          
<li>
            Reinstall shelves correctly and push food items back if they are
            sticking out.
          </li>
          
<li>
            Make sure bottles in the door bins are standing upright and not
            preventing the door from closing.
          </li>
          
<li>
            If the freezer door is left open, heavy frost can form and block
            airflow, preventing your refrigerator from cooling properly.
            <br/>Make sure the freezer door is fully closed as well.

          Step 4. Wait if your refrigerator was recently installed or serviced
        </h3>
        <p class="text">
          If the refrigerator was just installed or recently serviced, it may
          take some time to return to normal cooling performance.<br/>
          Depending on the amount of food stored, it may take 2–3 days for the
          temperature to stabilize
