Unit runs a lot. Doesn't condense much water. Sometimes fan runs alone, sometimes compressor runs alone.
This LG Dehumidifier is in a fairly dry basement. When unit is condensing well, the humidity display has a 10 degree offset - it reads 70% when it is 55 - 60%. The unit cycles a lot - maybe five minutes on and off. The problem now is that the fan might run without the compressor or the compressor sometimes runs without the fan. It doesn't condense water like it did when new. The filter and unit is spotlessly clean. It runs almost continuosly now with little drop in humidity.

Re: Unit runs a lot. Doesn't condense much water....
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:

A dehumidifier is basically the same thing as an air conditioner but both coils (condenser and evaporator) are in the same unit meaning a dehumidifier exhaust warm air in the same room it is in. running a dehumidifier would make an air conditioner run more because of the warm exhaust, when you run an air conditioner it acts like a dehumidifier and dries the air. As far as saving energy it all depends on the size of the AC and dehumidifier and the size of the room. If you want warm dry air, use a dehumidifier; if you want cool dry air run the AC but not both. How do all these parts fit together to pull moisture from the air? It's fairly simple, but very effective:
A fan collects air from the surrounding area and pulls it into the dehumidifier.
As the air passes through, it comes into contact with the dehumidifier's cooled coils. These coils use condensation to pull moisture from the air. The collected moisture remains on the coils and drips into the dehumidifier's reservoir.
The dehumidifier reheats the air and exhausts it back into the room.
A dehumidifier usually has a removable plastic bucket for are reservoir; most buckets also have a place where you can hook up a hose so the collected water can drain straight into a floor drain or pump. This frees you from having to remember to dump out the water. But don't worry too much about the reservoir overflowing -- most dehumidifiers also have an automatic shut-off. If you're using a dehumidifier in extremely moist conditions,however, or if you need to keep your dehumidifier on all the time, you should look into a unit with a built-in condensate pump, which regularly pumps water out of the unit's reservoir rather than simply relying on gravity to empty it as a hose does.
You may have the humidity level set to high. Usually anything above 50%, will show little results, unless your house is flooded.. Turn the humidity setting to the lowest level that your humidifier has and give that a try.
The fan runs a lot, because it's designed to almost constantly move the air around. That way, if the humidity level rises above the setting on the dehumidifier, it can sense it and the compressor will turn ON.
Your dehumidifier is similar to a refridgerator or air conditioner. It has a compressor and coils, and a fan. Basically, the unit has to **** in air with it's fan, and as the humid air goes across the cold coils, the humidity condenses in to water. If the coils are not getting cold, they won't condense any water, or if the fan isn't running, or the coils are dirty. If you check your unit over, see if you can tell if anything isn't working. Make sure the control knob is set at the highest setting. If the compressor lost it;s refridgerant charge, and won't get cold, it isn't probably worth fixing
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.
It sounds like an issue with the control bord. This dehumidifier should have a 5 year warranty through LG. You will need to have this serviced. If it is under warranty by LG they will either refer you to a local repair shop and they will pay for the repair or they will replace it if you do not have a repair shop in your area. Call them and explain the problem to them. Make sure that you have your reciept. Here is the contact information for LG:
I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad. Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.
