Step-by-Step Guide To Repairing LG Fridge Compressors

LG, one of the world's leading manufacturers of home appliances, has a reputation for making the best refrigerators. However, despite the high quality of its products, things can still go wrong. One of the most common issues is a faulty or failing fridge compressor. The compressor is the heart of your fridge's cooling system and, if it develops an issue, your fridge's performance will significantly decrease. However, don't worry! Repairing an LG fridge compressor isn't as hard as it might seem. This step-by-step guide will walk you through the entire process. But, before diving into the repair process, let's discuss the compressor's role. The compressor, located at the back of your fridge, is responsible for maintaining the refrigerator's temperature by circulating refrigerant via the condenser and evaporator. The signs of a faulty compressor include an abnormal level of noise, warm freezer or a fridge that can't maintain the desired temperature. If this is the case, you may need to repair, or in some cases, replace your fridge compressor. Step 1: Diagnose the Fix First, ensure that the compressor is the likely issue. Unplug the refrigerator and listen for any clicking sound when you plug it back in, any unusual noises may indicate a compressor problem. The compressor may also be warm or hot to the touch. Step 2: Gather Your Tools Setting up your toolkit is the next step in this process. A refrigerator compressor repair may require the following: a socket/ratchet set, screwdrivers, a multimeter for testing continuity, and pliers. You will also need a compressor start relay replacement if faulty. Step 3: Safety First Before beginning your repairs, make sure you've undertaken safety precautions. Disconnect the fridge from its power source to avoid electrical shock. You should ideally wear safety goggles and durable gloves to protect yourself from accidental injuries. Step 4: Access the Compressor Locate the compressor at the rear base of the unit. You will likely need to remove a few screws to take off the back panel. Remember to keep the screws safely so you don't lose them. Step 5: Test and Replace the Start Relay The start relay is the device that powers the compressor. Use your multimeter to test its continuity. If it's not functioning correctly, replace it. You can easily order a replacement online at a fractional cost of a new compressor. Step 6: Reassemble Your Fridge Once you've replaced the start relay, you can put your fridge back together. Reattach the back panel using the screws you safely kept aside and plug your fridge back into its power source. Step 7: Monitor Your Fridge Don't assume your fridge is fixed right away; it will take a few hours to reach its optimal temperature. Monitor the refrigerator's performance to ensure it's working correctly. In some cases, the compressor itself might need replacing. Please note, replacing a compressor is a much more complex task and often requires a trained professional. It involves recovering and recharging the refrigerator's refrigerant, which is a task that requires specific equipment and EC (Environmental Compliance) certification in many jurisdictions. The cost of a compressor along with the labor cost for installing it might make it a better option to consider a new refrigerator. In conclusion, thanks to this step-by-step guide, you are now well-equipped to repair your LG fridge compressor by replacing the start relay. Remember, this guide is meant for relatively simple compressor issues, with replacement of the start relay. For more complex problems, especially ones that involve handling refrigerant, it's best to hire a professional.
