LG Refrigerator Compressor Repair: A Beginner's Guide

As a central component of your LG refrigerator, the compressor plays an indispensable role in the overall functioning of your refrigeration unit. If your refrigerator stops cooling effectively, it could be a sign that your compressor needs repair. As a beginner with little to no experience, you may feel apprehensive about getting hands-on with this essential appliance. However, with some basic knowledge, right tools and a little patience, you can address minor issues on your own. This guide is designed to help you methodically diagnose and possibly repair any problems you might encounter with your LG refrigerator's compressor. Before diving into the repair, it's crucial to understand what a refrigerator compressor is and how it works. As the heart of the refrigerator, the compressor comprises a motor with a pump that moves refrigerant through the system, maintaining a balance of heat and cold. As such, any disruption can lead to significant performance issues. To efficiently identify the problem, it's best to understand what signs indicate a compressor issue. Typical signs include: the refrigerator not cooling enough, a constant run time, or unsettling noises from the rear side. If you're experiencing one or more of these symptoms, it could be an indication that your compressor needs attention. Before beginning any diagnostic work, ensure the refrigerator is unplugged to avoid any potential risks. The compressor of your LG refrigerator is likely located at the back near the lower portion, inside a housing unit. The first thing to consider is the compressor's motor. Refrigerator motors are usually silent when running in optimal conditions. If you've noticed a clinking or buzzing sound, it might be an indication of a malfunctioning motor. Since the motor is integral to the compressor, you may require professional help to repair or replace it. Next, check the compressor fan. If the fridge is not cooling properly, it could be due to a malfunctioning fan, preventing the compressor from cooling. The fan should spin freely; if it doesn't, replace it by unscrewing the old one and installing a new one carefully. For compressors that are running continuously without cycling off, the issue might be with the relay, often due to a power surge. The relay starts the compressor and keeps it running until the fridge attains the desired temperature. A broken relay causes the compressor to run ceaselessly. You can purchase a relay start kit from an LG service center, ensuring it matches the model of your appliance. Replacing it involves removing the broken one and attaching the new relay to the compressor. The compressor might also fail to start due to a defective thermostat. To check, turn the thermostat to the lowest setting, and slowly increase it. If the compressor does not kick in, the thermostat might need replacing. Lastly, check the coils. LG refrigerator condenser coils should be clean without any dirt or dust accumulation. Dirty coils can cause the compressor to build pressure, leading to potential failure. Cleaning coils is as easy as using a coil brush or vacuum to remove the dirt. Resolving issues with your LG refrigerator compressor might take a fair amount of time, especially if you're a beginner. However, these general troubleshooting tips can help you navigate minor issues. Remember, when in doubt, it's always best to contact a professional technician. Delving into repairs beyond your knowledge can lead to more harm than good, potentially causing more damage to your appliance. In conclusion, knowing how to diagnose and handle minor issues with your LG refrigerator compressor can help save both time and money. However, the key to ensuring the longevity of your refrigerator hinges predominantly on regular maintenance checks. Taking the time to clean and inspect the appliance can help prevent minor issues from escalating, saving you from expensive repairs or replacement down the line.
