Replacing the compressor on an LG refrigerator can be a complex task, but with the right tools and instructions, it is possible to do it yourself. Here is a step-by-step guide to help you through the process:
1. Safety first: Before starting any repair work, make sure to unplug the refrigerator from the power source to avoid any electrical accidents.
2. Gather the necessary tools: You will need a new compressor, a replacement filter drier, a refrigerant recovery system, a vacuum pump, a manifold gauge set, a tubing cutter, a flare nut wrench, and a soldering kit.
3. Empty the refrigerator: Remove all the food items and shelves from the refrigerator to access the compressor easily.
4. Remove the old compressor: Locate the compressor, which is usually located at the back of the refrigerator. Disconnect the electrical connections and tubing attached to the compressor. Use a tubing cutter to cut the refrigerant lines and remove the old compressor.
5. Install the new compressor: Attach the replacement filter drier to the new compressor using a flare nut wrench. Solder the refrigerant lines to the new compressor, ensuring a secure connection. Reconnect the electrical connections.
6. Evacuate and recharge the system: Use a refrigerant recovery system to remove any remaining refrigerant from the system. Once the system is empty, use a vacuum pump to remove any moisture or air from the lines. Finally, recharge the system with the appropriate amount of refrigerant using a manifold gauge set.
7. Test the refrigerator: Plug the refrigerator back into the power source and turn it on. Monitor the temperature to ensure that the new compressor is functioning properly.
