Expert Techniques For Troubleshooting LG Fridge Compressors

LG refrigerators are renowned for their reliability, efficiency, and advanced features. However, every machine is prone to breakdowns over time, and LG refrigerizers are no exemption to this rule. One of the crucial components of these refrigerators is the compressor, a 'heart' of the appliance that circulates refrigerant to create an adequate environment for food preservation. When problems arise with LG refrigerators, it always worth paying some attention to the compressor. A fault in this essential piece can result in your fridge not cooling properly, causing a potential meltdown in food storage. This article will guide you through expert-backed techniques to troubleshoot LG fridge compressors. Understanding The Role Of The Compressor The compressor is essentially the 'engine' of your fridge, whose primary function is to compress the refrigerant vapor that is produced, converting it to high-pressure hot vapor before it's moved to the condenser. Here, the refrigerant is liquefied and cycled back into the fridge, where it absorbs and carries away heat to maintain a cool environment. A performing compressor results in a well-functioning refrigerator, while a faulty one can inflict mayhem on your food storage. Signs Of Compressor Issues Before applying troubleshooting techniques, it is crucial to determine whether the compressor is problematic. Not all fridge malfunctions stem from the compressor. Strange noises, a fridge that's continuously running, or inefficient cooling might denote compressor issues. If the fridge isn't cooling at all, but the light comes on, and the evaporator fan runs, the likelihood of a faulty compressor is high. Checking For Overheating One common problem with compressors is overheating. It can be caused by dirt and debris clogging the fridge's condenser coils, inadequate ventilation, or a faulty condenser fan. By placing your hand on the side of the compressor, you can assess whether it is unusually hot. If it's overheated, ensure the area around the fridge is clean and uncluttered. Remove any dust or grime from the condenser coils, using a brush or vacuum cleaner. Lastly, inspect the condenser fan for any blockages, and if it's not working, you may need to replace it. Using The Multimeter A multimeter is quite instrumental in diagnosing compressor issues. You can use it to check if the compressor is getting the proper voltage. To do this, you need first to locate the compressor. It's usually found at the back of the fridge, down low, and encased in a metal housing. Then unplug the fridge, disconnect the start relay from the side of the compressor, and use the multimeter to check for continuity. If it doesn't show any continuity, the relay is defective and should be replaced. In other cases, you can also use the multimeter to check if the motor windings in the compressor are defective. With the compressor still unplugged, touch one probe to the common terminal, which is usually marked by the letter 'C' on the start capacitor. Touch the other probe to the RUN ('R') and then the START ('S') terminal. If the multimeter doesn't show any resistance, then the compressor might be faulty. Engaging A Professional Given the complexity of compressors, sometimes the best troubleshooting technique is consulting a professional technician. Training and experience go a long way in dealing with compressor problems. A qualified technician can quickly spot and fix problems that you might overlook. They can also replace parts safely and accurately. Preventive Measures To avoid regular compressor hitches, you should employ preventive measures. First, have a routine to clean the condenser coils regularly to prevent overheating. Always ensure there is room around your fridge to facilitate ventilation. Also, avoid overloading your fridge, as this puts pressure on the compressor. Regular professional servicing can also help detect and correct minor issues before they escalate into major problems. In conclusion, troubleshooting your LG fridge compressor need not be a daunting task. With careful diagnostic measures and the right tools, you can edge closer towards pinpointing the problem. Always remember, if the task seems too daunting, there is no shame in calling in a professional. They have the training and experience to handle such issues most efficiently and safely.
