        A small surface crack inside your refrigerator does not affect its
        cooling or freezing performance. If your refrigerator maintains the set
        temperature, it is operating normally and you can continue using it.

        Why Do Small Cracks Form Inside Your Refrigerator?
      </h2>
      
<ul class="cause-list">
        
<li>
          Physical Impact: Hitting the cold plastic inner wall with heavy
          containers or hard food items can cause cracks.
        </li>
        
<li>
          Temperature Changes: Frequently opening and closing the door allows
          warm outside air to mix with the cold air inside.<br/>
          This temperature difference causes the inner wall to expand and
          contract slightly, which may lead to cracks.

          Ensure your refrigerator and freezer maintain your set temperatures.
          Check that ice or ice cream in the freezer is not melting, and food in
          the refrigerator remains chilled.

        <p class="text">
          If the temperatures are normal, a small surface crack does not affect
          the refrigerator’s core operation. You can safely continue using your
          refrigerator as usual.

<span role="img" aria-label="Answer">A.</span> Thick insulation
            behind the inner wall helps maintain the temperature inside your
            refrigerator. A small surface crack does not leak cold air or
            increase energy use. <br/>If you are still concerned, contact LG

<span role="img" aria-label="Answer">A.</span> Yes, you can apply
            food-safe waterproof or clear tape over the crack. This helps
            prevent the crack from spreading and covers it for cosmetic reasons.
