If you’ve noticed that your LG refrigerator is not cooling as it should, or if there is a funny noise coming from your refrigerator, your refrigerator compressor may be bad. The compressor is the heart of the refrigerator that keeps it cool and functioning properly. In this article, we will explore what a refrigerator compressor is, its essential role in keeping your LG refrigerator functioning appropriately and ways to troubleshoot and diagnose problems that are commonly associated with a compressor.

What is a refrigerator compressor and how does it work?

A refrigerator compressor plays a vital role in keeping your LG refrigerator functioning optimally. It is an electric motor with a pump that compresses the refrigerant and circulates it through the evaporator and condenser coils. The compressor draws refrigerant from the evaporator coil, compresses it down to a high-pressure gas, which then travels through the condenser coils. The heat is then dissipated, and refrigerant is condensed back to a liquid state. This cycle continuously repeats itself to keep the refrigerator at a constant cool temperature.

It is important to note that the compressor is one of the most energy-consuming components of a refrigerator. Therefore, it is crucial to maintain it properly to ensure its longevity and efficiency. Regular cleaning of the condenser coils and ensuring proper ventilation around the refrigerator can help reduce the workload on the compressor and save energy. Additionally, if you notice any unusual noises or a decrease in cooling performance, it may be a sign of a faulty compressor that needs to be repaired or replaced by a professional technician.

Symptoms of a bad compressor in LG refrigerators

Recognizing signs of a bad compressor in your LG refrigerator is essential in preventing further damage to other parts of the appliance. Some of the most common signs of a bad compressor include:

  • Excessive vibration or strange noises coming from the refrigerator
  • Warm or hot to the touch exterior surface of the refrigerator
  • Frost accumulation in the freezer section of the fridge
