My dehumidifier is about 2 years old. The unit says the humidity is "lo", but everything feels damp. The unit does not collect any moisture. I put a thermometer in the basement that also measures humidity. That reads 75%.

Re: humidifier measuring wrong %
This will need to be serviced. LG has a 5 year warranty on these models. They usually will tell you of a service center nearby which will service it free of charge since it is under warranty. If you do not live near a service center they may ship you a replacement and you send your old dehumidifier back to them. Make sure you have your reciept when you contact them so they can verify it is 2 years old.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

Chris, it may be that the humidity extraction level (%) may be set to high. Lower it to 32 - 35%. Also, a dirty or clogged air intake filter will also cause the problem.
Not enough clear air space around the unit. You must maintain a minimum of 12" clear air space around the entire unit.
If it's a basement application - The air temperature at floor level is colder, than at chest height. Raising the unit up onto a sturdy table or cabinet that can handle the weight of the unit and a full bucket of water, normally resolves that problem.
On the more serious side ... The unit is 7 years old and the compressor may need to be recharged with R14 refrigerant. Or the humidity sensor may have failed. In either case, since the unit is 7 years old, it would probably cost you as much to repair, as it would to replace it. That's a decision you'll have to make.
Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.
My first thought is that there's not enough moisture/humidity in the air, for the setting you have the humidifier set on. The higher the setting or percentage (i.e. 60%) means that the level you want to maintain. Which may be find in the cod winter months. In the Hot summer months, you want as low a level of humidity as possible (i.e. 45%).
My second thought is that the air intake filter and the coolant coils need cleaning, since it has been used in 2 years. It's just sat around gathering dust and spiders.
And finally, the collection bucket, may not be inserted properly and when the unit starts up the vibration dislodges the bucket just enough, so that it's not making contact with the safety switch. Sometimes when this happens, the Full light indicator will come ON, even if the bucket is empty.
Hope this helps you to start troubleshooting the problem. Please let me know.
Hi, Mindy! The following is an overall review of what causes the problem you listed.
If the room air is less than the set air, then there is no water in the
bucket, because there is almost no humidity in the air. If it is winter,
there is likely not enough humidity in the air to have water collect in
A dehumidifier will only pick up humidity out of warm air. If you are
running a dehumidifier in your basement in the winter, the room may be
damp, but too cold for the dehumidifier to pull out the humidity.
Try running the unit in the bathroom after having a hot shower without
the bathroom fan on. If working correctly the unit should draw water. In addition, if you set the humidity level you want to maintain higher the actual humidity level in the house or room, it won't pickup and collect any moisture. The fans on most of the dehumidifiers on the market today run almost constantly. They do this, so that the room air is always moving and if humidity is detected, it will extract it.
Hope this helps you understand how dehumidifiers function and what you can expect from them under given circumstances,. In fact, there may not be anything mechanically wrong with yours. But, to make sure, do what is suggested above to test the unit.
THE LOWER THE % SETTING, THE MORE MOISTURE THE DEHUMIDIFIER WILL REMOVE!!!
I have a Provic dehumidifier mainly to remove damp from walls in my 1900s terraced house ( 3rd DPC failed, another on its way). I've read a lot about the technical side and all I wanted to know was 'do i set it on the highest or lowest % to extract moisture from the walls'. I rang the Managing Director at Provic (his contact details are given on their website) who was very helpful. He advised that the lower the setting, the more damp would be removed from the walls and therefore the air, as the water passes from the wall into the air. My DH ranges from 40% to 70% so he advised me to set it at 40% in the worst affected room to remove as much moisture as possible from the walls. As the moisture is removed, the DH will collect less water and set itself to the correct level anyway. He advised me that when as much water as possible has been removed from this room and the DH % will not drop any lower, to move it to a more central position in the house, such as the hallway to then start setting the rest of the house to the correct humidity level. I set the DH to 40% and left it on overnight closing all doors to the affected room and removing containers of water such as a vase of flowers. When I got up in the morning it had switched itself off as it had already collected 3 litres of water! You do have to be careful not to over dry the air as everything, furniture and electricals, naturally needs moisture, but for a short term, quick drying solution, this level is ok.
Hope this helps!
In plain English, the Percentage setting on your de-humidifier is the percentage of moisture that you want to maintain in the air. Relative humidity level range from about 10% (VERY dry air) to almost 100% (VERY damp air). When relative humidity is 100%, water vapor in the air will turn into rain, condensation, dew, snow or frost. 50% humidity is usually a comfortable level, but that will also depend on air temperature. The more moisture there is in the air, the warmer it feels and conversely. Warm air will hold more moisture than cooler air.
Your body is cooled when moisture on your skin evaporates into the air, carrying body heat with it. As the humidity in the air rises, less of your body moisture is able to evaporate and thus your body feels wamer. Lower humidty allows moisture from your body to evaporate more quickly and you feel cooler, both at the exact same temperature.
If everything is running and no water is being produced the system may have lost its refrigerant. There are two motors in dehumidifiers. One is the fan and the other is the compressor. Make sure they are both running.
