Troubleshooting LG Refrigerator Compressor Problems: A Step-by-Step Approach

Refrigerators are essential appliances in our homes. They help us preserve our food and drink, ensuring we have fresh meals every day. Among the popular brands, LG refrigerators have earned a reputation for durability and efficiency. However, even with the best models, some issues may arise over time hindering their operation. One of the most prevalent issues that users face lies with the compressor. The compressor is primarily the heart of your refrigerator's cooling system. Understanding how to troubleshoot any problems associated with it is paramount to ensuring your refrigerator remains in optimal working condition. The compressor is what pumps refrigerant throughout your fridge's cooling system. If it breaks or has any issues, it can result in your refrigerator no longer cooling efficiently, or at all. This can be a big issue, especially during summers when the refrigerator usage spikes. Now, before you think about calling in a professional, there are several troubleshooting steps you can perform by yourself. Firstly, it’s essential to recognize the signs of a problematic compressor. Unusual noises, often a buzzing or humming that lasts longer than a minute, can sometimes indicate an issue with the compressor. In other cases, your refrigerator might not be cooling your food properly, and there might be a temperature change. It is, however, important to confirm if the problem lies with the compressor. The easiest way to determine if the compressor is the issue is by performing the "hard-start" test. Unplug your fridge and plug it back in; if the compressor doesn't kick in within a minute, it may have a problem. Also, you can check the temperature inside your fridge. If your refrigerator is not cool enough despite setting the right temperature, the compressor might be the problem. Once you are sure the compressor is the issue, the steps to troubleshoot a compressor problems entails: 1. **Check the Compressor Motor** At the back of your fridge, the compressor is housed. It can be identified via a cylindrical component containing a fan. A compressor issue could be down to the motor. Test it by unplugging the fridge and accessing the wiring to the compressor, recognizable by the three prongs. Using a multimeter, you can verify whether the motor is encountering any issue. 2. **Clean the Coils** Dirty coils can also lead to a compressor problem. To clean them, unplug the refrigerator, and locate the coils - they are either at the back or beneath the fridge. Use a vacuum cleaner to clear basic dust, and for a more thorough cleaning, a coil brush should work. 3. **Check the Compressor Fan** If the compressor fan is not turning, it could lead to massive problems. To find the fan, you can look at the back of the fridge. If it's not spinning when the compressor is running, it's an indication you need to replace it. However, if the fan is blocked by something, it may also prevent it from spinning. 4. **Check the Start Relay** The start relay helps to start the compressor. if it’s defective, it might be the cause of the compressor issue. To check, remove the start relay and shake it; if it produces a rattling sound, it needs to be replaced. Before you decide to open up and fiddle with your refrigerator's internals, keep in mind that refrigerators use high voltage. If you are unsure or uncomfortable about any of the steps, it's best to leave it to the professionals. If you’ve tried all the troubleshooting steps and your refrigerator still isn't cooling, it may be time to call a professional repair or perhaps even consider replacing your refrigerator depending on its age and the cost of repairs. Remember that routine maintenance improves the refrigerator's life span. Therefore, regularly cleaning it, checking its temperature and ensuring it's not overloaded can help prevent problems before they arise. Bearing these troubleshooting steps in mind, you can ensure your LG refrigerator's compressor remains in the best possible condition, keeping your food fresh for longer.
