Expert Techniques For LG Fridge Compressor Troubleshooting

The LG fridge is renowned for its distinctive features and its longevity. However, like all other electrical devices, occasional issues and faults may arise, keeping your fridge from functioning optimally. One of the most common problems that LG fridge owners experience is problems with the fridge compressor. This article delves into expert techniques and handy tips for successfully troubleshooting your LG fridge compressor. The compressor is an integral part of a fridge, and its primary function is to compress refrigerant vapors from the evaporator coils and circulate them through the condenser coils. In simple terms, it is the component responsible for providing the necessary cooling inside the fridge. When the compressor fails to perform its function, the end result is a warm fridge. Several indicators of compressor problems include the fridge failing to cool, strange noises coming from the fridge, the compressor getting too heated, or even the circuit breaker tripping due to a short circuit. Understanding the problem is one thing, but finding a solution can be challenging, especially if you aren't an expert. So here are some expert techniques to troubleshoot your LG fridge compressor: 1. Listen for Unusual Noises: Unusual noises, like hums and buzzes, indicate that the compressor may be faulty. However, not all noises mean trouble. Some are inherent to the regular operation of the fridge. The problem lies when the noise gets noticeably louder or when rather unfamiliar sounds emanate from the fridge. If that's the case, the compressor might be damaged or worn out. 2. Test the Compressor: To ascertain the source of the issue, you should test the compressor. First, unplug the fridge, locate the compressor, and remove the relay switch. Use a multimeter to measure the resistance of the compressor’s terminals. Normal readings typically fall within the 3 to 11 ohms range. If the reading is much lower or higher, your compressor has a problem that needs to be addressed. 3. Faulty Compressor Motor: A faulty compressor motor can cause your fridge to stop cooling. Diagnosing a compressor motor involves a series of tests. One way is by using a multimeter to check for continuity in the motor windings. A positive continuity test implies that the motor is fine, while a negative one indicates a problem with the motor windings. 4. Check the Compressor Fan: This approach involves checking the fan adjacent to the compressor, which aids in cooling both the compressor and the condenser. Dust and debris accumulated on the fan can diminish its effectiveness, thereby increasing the compressor's temperature. A non-functioning fan can also lead to the fridge not cooling correctly. Thus, periodic cleaning and maintenance of the fan are necessary. 5. Overloaded Compressor Overload Protector: An overloaded compressor may not start, causing the fridge to underperform. Check the compressor's overload protector by testing for continuity. The overload protector is a small device that helps prevent the compressor motor from overheating. 6. Inspect the Capacitor: An issue with the compressor's start capacitor can prevent the compressor from starting or can cause it to run intermittently. A bad capacitor can be identified by a bulging or leaking capacitor. You can test the capacitor's working condition using a multimeter. Repairing the compressor is a labor-intensive task, especially if you lack experience in handling electrical appliances. The easiest way to avoid a defunct compressor is through regular maintenance, such as cleaning the components and ensuring that they are free of dust and debris. Always remember to unplug the fridge before performing any testing or repairs. Also, the compressor of a fridge uses potential relay and a start capacitor, which are sensitive to electric variations. It's best to use a surge protector to protect your fridge from power surges, as they could potentially damage the compressor. For any challenges faced during troubleshooting, an appliance repair professional is your best bet. It's not worth taking a risk if you are unsure of your abilities. Trained experts can diagnose and fix the issue with utmost precision, ensuring the longevity of your fridge. In conclusion, the compressor is a crucial component of a fridge, and any issues with it can greatly impact the performance of the refrigerator. While troubleshooting, it's essential to adhere to safety protocols to avoid any kind of mishaps. After identifying the issue, if you are not confident or find the task too challenging, given the vital role the compressor plays, it's essential to call for professional help. The goal is to restore your fridge to its optimal state, providing you with uninterrupted service, convenience, and comfort.
