Hi,
The humidity switch (Hydrometer sensor) may be at fault or compressor or fan is not running.
First You could go directly to the compressor and make sure it is or is not getting power first. If the compressor has power then the compressor is suspect (sometimes when 1 wont start it gets hot to the touch) In any case the fan(s) should run with it on and trying to dehumidify.
2 KINDS of CONTROLS for your DEHUMIDIFY
If it has an electronic display the sensor will be a small probe close to the inlet of the air inlet circulation. Maybe its not in place.This type control is not something that can usually be checked without an ohm meter, thermometer, and Hydrometer or Psychometric measuring device to arrive at the wet-dry bulb temperatures thus determining the humidity and charts to determine the resistance value of the sensor(s). So replace the board and sensor on this type
If everything is clean on the coils and the filter is clean it should work.
I would recomending you to contact LG because they have a 5 year warranty on LG GOLDSTAR dehumidifiers. Make sure that you have your reciept. Usually what they will do is locate a shop near you and it can be serviced there. LG will pay the bill. Or if there is no local shop they will send you a service tag for your old unit and ship you a replacement unit. Contact LG and explain this problem to you. Everything should be covered under warranty still
Please leave me comment, if you need further assistance
