How to Troubleshoot Unusual Noises From Your LG Refrigerator

Most noises from your LG refrigerator are normal and happen as parts operate or temperatures change. However, unusual noises can occur if the refrigerator isn't level, frost builds up around a fan, or a component needs service. Identify the type of sound below to find the right solution.

What to Check First

  1. Cause: This sound occurs when the valve opens and closes to control the flow of refrigerant through the refrigerator.
  2. What to do: No action is needed. This is a normal operating sound that may occur for about seven seconds once a day, or for about three seconds every hour.
  3. Cause: These sounds occur when the compressor produces cold air or when the fan circulates it. If you open the doors frequently or place hot food inside, the motors may run faster and sound louder as the refrigerator lowers its internal temperature.
  4. What to do: No action is needed. The motor speed and sound will naturally decrease once the refrigerator reaches the set temperature.
  5. Cause: These sounds occur as refrigerant flows through the cooling tubes. You may also hear them during the defrost cycle when water from melting frost drips onto the heater and evaporates.
  6. What to do: No action is needed. These are normal sounds that occur as the refrigerator cools and maintains its internal temperature.
  7. Cause: Plastic shelves and internal components may expand or contract slightly as the temperature inside the refrigerator changes.
  8. What to do: No action is needed. This is a normal sound caused by natural thermal expansion, similar to the sound of ice cracking as it melts.
  9. Cause: When you open the refrigerator door, warm air enters and changes the internal pressure. This causes air to escape through the drain tube.
  10. What to do: No action is needed. This is a normal sound caused by natural airflow when you open or close the doors.

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.
