If your LG Air Conditioner experiences refrigerant leakage, it could stem from a clog in the refrigeration cycle or a defective compressor.
Why doesn't the high pressure rise quickly at the beginning of operation in my LG Air Conditioner?
If your LG Air Conditioner's high pressure doesn't rise quickly at the start, it might be due to an excessive amount of refrigerant.
What causes low current in my LG Air Conditioner?
If the current is low in your LG Air Conditioner, this could be caused by a defective compressor or a defective 4-way reverse valve.
