Troubleshooting LG Refrigerator Compressor Problems

Fridges play an integral role in every kitchen, preserving our food and drinks at optimum temperatures. Just like any other mechanical piece, refrigerators often encounter various issues that influence their overall performance. A common problem faced by refrigerators involves the compressor, the heart of the refrigeration cycle. Troubles with the compressor can significantly affect the cooling system. This article will focus on troubleshooting LG refrigerator compressor problems, providing a guide on how to identify, diagnose and resolve them. LG is a well-renowned company known for its high-quality electronics, including refrigerators. However, despite their top-notch quality, their fridges are not immune to compressor issues. The compressor is a critical component of the fridge. It's responsible for the refrigerator's capacity to cool items by compressing refrigerant and circulating it through the evaporator and condenser coils. Therefore, understanding how to troubleshoot these problems can save you a lot of money and help you maintain a long lifespan for your fridge. 1. Compressor not running If your LG refrigerator isn't cooling properly, the most likely culprit is the compressor. If the compressor is not running, it can't maintain the cool temperatures within the refrigerator. This problem can be diagnosed by the constant cycling on and off or the buzzing sounds your fridge makes. Usually, a compressor not running is often due to the start relay or the overload protector. You may need to replace these parts if they are not functioning correctly. You can test it by unplugging the fridge, accessing the compressor, and removing the relay switch to check for signs of damage or burning. 2. Compressor getting hot Another problem you may encounter is your LG fridge's compressor getting hot or overheating. A fridge's compressor generally gets warm, but excess warmth or overheating is a clear sign of a malfunction. When the compressor overheats, it's likely to shut down, causing the fridge to lose its cooling capacity. Overheating often results from clogged condenser coils. These coils dispel heat as the refrigerant passes through them; when they get dirty, they can't work efficiently, causing the compressor to labor and overheat. Regularly cleaning the condenser coils with a brush or vacuum might prevent overheating. 3. Refrigerator runs but does not cool Sometimes the refrigerator runs normally, but it doesn't cool. This could imply a problem with the compressor. Despite the fridge being on, a faulty compressor may not be able to pump the refrigerant around the fridge properly, causing insufficient cooling in the fridge. You'll need the help of a professional to confirm that the compressor is indeed the problem. They may have to check the compressor motor's electrical readings or if the compressor is damaged internally. It may require a replacement if it's damaged or if repairing it would cost much. 4. Excessive fridge vibration While operating, the LG refrigerator compressor is known to produce a low humming noise that's barely noticeable. However, if you start to hear heavy vibrations or louder-than-usual noises while in use, it could be a sign that your compressor is malfunctioning. Excessive vibration can be caused by faulty start components or damaged springs inside the compressor. If this is the case, you might need to replace the compressor, which is generally a more complex task that may require a professional's intervention. 5. Fridge is tripping the circuit breaker If your LG refrigerator trips the circuit breaker, it could be a sign of a bad compressor. When the compressor has an electrical problem or is stalled due to an internal issue, it can draw more electrical current, causing the circuit breaker to trip to prevent an overload and potential fire. Don't keep resetting the circuit breaker and ignoring the problem. Reach out to a technician for guidance; if it's indeed the compressor causing the trips, it may need to be replaced. Troubleshooting LG refrigerator compressor problems can be a challenging task, especially for non-technicians. However, understanding some common problems and potential solutions can help you diagnose and maybe fix the issues before seeking professional help. Be sure to regularly clean and maintain your LG refrigerator to limit the chances of compressor issues. Also, remember to always call a trained technician when faced with complications beyond your knowledge. Regular servicing and proper handling are crucial in maintaining your refrigerator's efficiency and longevity.
