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 Air Conditioner?
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.
