I have a LG LD50EBL Need to know if I have a problem uint runs 15min then fan truns off . Compressor sound like it is running but not compressing Then after maybe 5 min fan starts back up and compressor turns back on in the compressor mode. This unit has a silenoide on a high or low presure line.It seems too be working fine and removing Moister. Can you help with this.
Your unit is probably operating in defrost mode. When you use a dehumidifier in a cold room, the condensing coils can freeze water. The unit senses this and thus stops the compressor until the water frozen on the coils melts. Then it resumes its cycle. This is a problem you will have during the winter months. It makes the operation of the unit inefficient, but this is otherwise normal behavior.

if by turn off do you mean make the fan stop running ? if so sometime in the past few years someone decided to make machines like this run the fan all the time , but they do cycle the compressor motor to regulate the rooms humidity level
Sounds like the compressor is inoperative. Most, if not all new units have no means of recharging the freon if it leaks out. If the coils are not cooling, the compressor is not operating and the unit will not dehumidify.
Your sealed system has a leak. Check your owners manual for sealed system warranty. It should be five years on the sealed system. You need an LG dealer to submit an exchange order for you and LG will send you another unit.
Compressor won’t Start
The Main reasons that this will happen
1 - A bad run capacitor (silver or metal capacitor)
It’s either shorted, grounded or open.
If it’s shorted a lot of times it will bulge out, (sometimes slightly)
2 - A bad start kit ( plastic capacitor and Relay connected to it )
The capacitor is either shorted or open
The relay either has an open coil between terminals #1 and #5
Or the relay is stuck.
Any time you change the capacitor or relay you should change
the other, especially if they are over a year old.
3 - A loose, burnt or disconnected wire
4 - Wired wrong
5 Compressor is open (windings burnt open)
6 Low on charge not getting enough cooling back to compressor, (Feel top of compressor to see if it’s hot it shouldn‘t be)
7 Some compressors have a black plastic overload under the compressor cap which could be bad.
remove the back airfilter, and touch the tubes while the unit is running, if nice and cold, all is well, there just isnt any moisture there. but if compressor is running and tubes are warm , means freon/coolant has leaked out
Is the compressor running or is it just the fan? If its just the fan it is because it is cycling the air and it uses that air flow to check the humidity in the air. If the fan runs non-stop and the compressor does not turn on or the fan does not shut off there is a problem with this unit and you will need to replace it. Since it is brand new you should still be able to return it to the store.
You may also want to check the coils and make sure they do not have dirt or dust on them. If they are clean you may have an issue with the refrigerant level which will cause the coils not to cool properly. For that you will want to contact LG. There could be an issue with the compressor also. LG backs alot of their models with a 5 year warranty. Contact them and let them know about your issue. Make sure you still have your reciept. Here is their contact number:
