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 LS-L1261NL 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.
Why does my LG Air Conditioner have higher suction pressure and normal temperature?
If your LG Air Conditioner has higher suction pressure and normal temperature, it might be due to an excessive amount of refrigerant. In this case, high pressure does not quickly rise at the beginning of operation.
What causes higher suction pressure and high temperature in my LG LS-L1261NL?
If your LG Air Conditioner has higher suction pressure and high temperature, this could be caused by a defective compressor or a defective 4-way reverse valve. The current is low.
