What to do if the current is low on my LG Air Conditioner?
If the current is low in your LG Air Conditioner, it could be due to a defective compressor. Check the temperature and pressure of the refrigeration cycle to diagnose the issue.
Why does the high pressure not quickly rise at the beginning of operation of my LG LM-2164H2L Air Conditioner?
If the high pressure in your LG Air Conditioner does not rise quickly at the beginning of operation, it may be due to an excessive amount of refrigerant. Check the temperature and pressure of the refrigeration cycle.
