Essential Tools For Troubleshooting LG Fridge Compressors

The refrigerator, with its vital role in our daily lives, is a gadget we take for granted - that is, until it stops functioning. A fridge not cooling adequately will leave you with spoiled food and frustration, with the problem often tracking back to the refrigerator's compressor, also referred to as the “heart” of the appliance. This is particularly common in several LG refrigerator models. LG fridge compressors have been known to experience issues like not turning on, creating odd noises, or not cooling enough. Armed with the right tools and knowledge, you can diagnose, troubleshoot, and occasionally even fix some of the common problems. Let's discuss the essential tools you'll need if you find yourself troubleshooting a problematic LG fridge compressor: 1. Multimeter: A multimeter is an instrumental tool when diagnosing a faulty fridge compressor. This electronic measuring instrument combines several measurement functions in one unit. It can measure voltage, current, and resistance. When you suspect a compressor failure, this tool can be used to check the electrical continuity of the compressor's winding. 2. Compressor Tester: The compressor tester can help detect any issue with the compressor. It enables you to diagnose and determine whether the problem is with the compressor or the capacitor. This tool is valuable because it rules out the guesswork and provides a precise problem source. 3. Capacitor Tester: A damaged or faulty compressor start capacitor often leads to refrigerator compressor issues. The capacitor tester can check whether the start capacitor is in good working condition or needs replacement. 4. Infrared Thermometer: This device provides a non-contact way to measure the compressor's temperature. When a fridge compressor overheats, it will shut down, causing the refrigerator to stop cooling. 5. Ampere Meter: This tool tests and monitors the supply of current to the refrigerator. If the compressor is pulling too many amps, it may point towards a faulty compressor. 6. Screwdrivers, Pliers, and Wrench Set: Fundamental hand tools like screwdrivers, a set of pliers, and wrenches are essential for compressor troubleshooting. They can be used to open and secure components during your diagnostic procedures. 7. Safety Gloves and Glasses: Since you'll be handling electronic components, maintaining safety standards is crucial. High-quality safety gloves prevent electrical shocks, and safety glasses shield your eyes from sparks or any flying debris. Once you have these tools, the next step is understanding how to use them. Begin by unplugging your LG refrigerator. Use your screwdriver to remove the back panel, where you'll find the compressor. With your ampere meter, check whether the compressor is pulling too many amps. If the amp draw is normal, you can now use the multimeter. You should test for continuity between the common terminal and other terminals. Should you find there's an open circuit between these, the compressor might be the problem. While doing this, always check the compressor for overheating. If it's too hot to touch, chances are it's overheating. With your infrared thermometer, measure the temperature for a more accurate reading. Also, use the capacitor tester to check the start capacitor. The reading should be close to the capacitor's rating. If it's too high or low, replace the capacitor. If after performing these steps the compressor still doesn't work, chances are it's defective and needs replacement. Always consult with a professional if you're unsure about performing these checks yourself. In conclusion, troubleshooting LG fridge compressors is an attainable feat if you're equipped with the correct tools and a basic understanding of appliance management. The monetary savings, practical knowledge, and sense of satisfaction from resolving an appliance issue by yourself are well worth the time and effort, and you'll be better prepared to face any future refrigerator malfunctions head-on. However, remember that safety always comes first, and never hesitate to seek expert help when needed.
