Expert Tips For Repairing LG Refrigerator Compressors

LG, as a global brand, is known for its excellent home appliances, particularly refrigerators. Despite the high-quality engineering behind these devices, they sometimes experience issues. One of the most common problems related to LG refrigerators is compressor failure. The function of an appliance's compressor is to draw in refrigerant gas from the interior, compress it, and discharge it at high temperature and pressure. This process maintains an optimal cooling environment within the refrigerator. When this compressor fails, it could impede the refrigerator's efficiency significantly. Don't fret, though; many of these issues can be resolved at home without the need for a professional technician. So, if you have LG appliances at your home, this article will be a practical guide that helps you repair your LG refrigerator's compressor using expert tips and tricks. Before you start troubleshooting your LG refrigerator, remember to unplug it from the power source. While you perform these tasks at home, safety should never be ignored. Also, familiarize yourself with the basic parts of the refrigerator - this will make your job much easier. One of the first signs of a faulty compressor is the fan operating, but the refrigerator not cooling properly. If the temperature in the refrigerator compartment or freezer is higher than it should be, despite the settings, the compressor may be the culprit. If you notice a loud noise when the compressor engages or the fridge suddenly stops working, these are clear indications that your compressor may be faulty. The first thing to check is the compressor fan. On many refrigerators, including those manufactured by LG, the fan is visible on the backside. The fan's purpose is to cool the compressor when it's working. If you notice any blockages or that the fan is not running when the compressor is working, it's an indication that your compressor could be overheating, leading to inefficient cooling. Clean any dust or debris from the fan and its surroundings and check it again. If it is still not running, the fan may need to be replaced. A very common issue with the LG refrigerator compressor is related to the start relay, which aids in starting the compressor. If your refrigerator is experiencing an issue with starting or staying on, it could be because of a faulty start relay. To check this, you can use a multimeter to test the relay for continuity. If there is any deficit in the reading, you might need to replace the start relay. Another thing to examine is the compressor's motor. For this, you will need a multimeter again to test the motor for continuity. Remember to discharge the capacitor before testing, to avoid getting shocked. If you find the motor to be faulty, you will need professional help to replace it, as the process is quite complex. In some cases, the thermostat controls the refrigerator's temperature might be contributing to the compressor's issues. It might result in the compressor constantly operating, leading to a spike in your electricity bill. To test the thermostat, rotate it from the lowest setting to the highest, and listen for a click. If you do not hear a click, you probably should replace your refrigerator's thermostat. If none of these solutions work, there might be a more severe issue with your refrigerator's compressor. Compressor replacement is a job for a qualified technician as it involves handling refrigerant, which is a hazardous substance. Nevertheless, understanding these helpful troubleshooting steps will provide vital knowledge when you're working with a technician by effectively communicating the symptoms and possible causes. In conclusion, troubleshooting and fixing an LG refrigerator compressor can be an easy task, provided you have a basic understanding of how your appliance works and some guidance. They are resilient devices made to withstand long usage durations, but like all machines, sometimes they require a little care. With the tips provided in this article, it's now safe to say that this mechanically inclined task isn't a daunting one. Always remember, when you're in doubt, it's best to call in a professional.
