What to Check First
- If the lock is enabled, press and hold the [Lock/Unlock] button for 3 seconds to unlock it before adjusting the temperature.
- For optimal cooling and proper air circulation, we recommend filling the refrigerator to about 70% of its total capacity.
- Touch and smell check: 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.
- Condensation check: During the summer, if condensation forms on containers when warm air enters after opening the door, this is normal.
- Remove any items blocking the air vents inside the refrigerator.
- Also organize items in the freezer. (In most refrigerators, cold air is generated in the freezer and flows into the refrigerator. If airflow in the freezer is restricted, your refrigerator may not cool properly.).
- Reinstall shelves correctly and push food items back if they are sticking out.
- Make sure bottles in the door bins are standing upright and not preventing the door from closing.
- If the freezer door is left open, heavy frost can form and block airflow, preventing your refrigerator from cooling properly. Make sure the freezer door is fully closed as well.
- Follow the steps below to check whether your refrigerator is cooling properly.
Why This Can Happen
Symptoms can have more than one cause, and the correct steps depend on the exact model, installation and operating conditions. Use the checks above to narrow the issue before service.
