Freon is no longer used, it has been banned by the EPA. Never the less, the first thing you should do is clean the coils. If they are dirty, it will cause the unit to freeze up or frost over. Warm water and a mild dish washing detergent will do the trick. Wipe them off thoroughly and then dry them. Then apply a thin coating of WD40.

Another cause is using the unit in a basement application. The air temperature at floor level is colder than at chest level. Dehumidifiers struggle at temperatures between 40 & 65 degrees F (unless, you have a Low Temp Model designed for basement applications). Raising the unit up off the floor on to a sturdy table, counter top etc that can handle the weight of the unit and a full bucket of water, will generally resolve the problem

And finally, the defrost sensor may be faulty and needs to be replaced.

If none of the above solves the problem for you, have the refrigerant checked,. it may need to recharged.

Gary, if it's not collecting condensation, there are 5 basic, yet solvable reason s for this. One you have already taken care of - cleaning the filter.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have an analog unit
set the humidity extraction level knob to Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.


I hope this helps you to further troubleshoot and solve the problem. Thanks for choosing FixYa.

To find and remove the filer. First, turn the unit OFF & unplug it. Then remove the water bucket. The filter frame & handle will be located at the top of the bucket holder just behind the front louvers. If you have never removed and cleaned the filter, it may have a piece of plastic tape on it, which was used for shipping. Remove the tape & discard it. Pull the filter frame's tab handle straight down and remove the filter. It can either be vacuumed or if it's really dirty, washed in warm water and a mild dish washing liquid. Rinse thoroughly and shake off any access water. Allow it to dry completely, before reinstalling it. Never operate the unit without the filter in place. Doing so could cause damage to the unit.

Clean the filter at least once every two weeks.

I've misplaced the owner's manual on a DEN 500 P. What is a good basement setting for Summer in Central Ohio? Is a manual available on line?


I bought a cheap digital humidistat at Walmart to keep an eye on the humidity in my basement. I hung it on the wall not too near my dehumidifier. I have found that the settings on the dehumidifier are misleading, but I found a setting that keeps my humidity between 40% and 55% (at around 70 degrees), as measured by the humidistat.

My lg DEHUMIDIFIER model #LHD65EBL is no taking in any water. Cleaned the filter and coils.Installed the basket properly.Set the setting at 35 to70 and nothing happens. just runs. About 4 years old.


According to your Owner's Manual. once the humidity extraction level is set at 35%, you should push the minus (-) key one more time to turn the unit ON. It will now run continuously no matter what the humidity level is until the bucket is full.

In case you have misplaced your Owner's Manual, go to the link below and click on English. The Owner's Manual will download and you may print it for future reference.

Error message CH 24. Any ideas? I have the LD651EBL dehumidifier.


We;ve managed to clear this error, at least for the last 5 days. Remove the bucket, and reach up behind the front panel where there is a filter- ours was covered in dust. After cleaning this off, and resetting the machine (by pulling the electric plug out and re-inserting), the error went away.
Your mileage may vary.

Just wondering if this unit has a filter or filters that need to be changed?? (Frigidaire 70)


Yes, your unit has an air filter, that should be removed and cleaned at least once every two weeks, while in operation, The filter is located behind the louvers on the front of the unit. To access and remove it, remove the water bucket and just inside the bucket holder at the top of the opening, you will see a tab type of handle. This handle is part of the filter frame. Pull that down and out and the filter will come with it. Back flush the filter with clear warm water. Dry it thoroughly, before reinstalling it in the unit. Never operate the dehumidifier without the filter installed.

To assist you further, in case you have misplaced your Owner's Manual, I have included a link to the Manual for your model. You can download and print the manual for future reference.

How do I get to the air filter in order to clean it ??


To remove the filter. remove the water bucket. Then looh at the top of the water bucket cavity. You will see a small plastic pull type handle. This is the plastic frame for the air intake filter. Pull it down to remove frame and the filter. After washing an rinsing the filter, be sire it's completely dry, before installing it. Be sure you have turned the unit OFF and unplugged it before removing the filter.

My LG Dehumidfier 3850A20500H has stopped pulling moisture from the air it still runs but no wataer in the bucket what could be the problem? this starts happening after 1 year of purchase.


There are several things that can cause the problem you described. Most of which are easily remedied.

1. The humidity/moisture extraction level is set to high. Lower it to 35%

2, Air intake filter is dirty or clogged. Remove and clean the filter.

3. Refrigerant coils on the back of the unit are dirty and need to be cleaned.

4. Not enough clear air space around the unit. Maintain at least a minimum of 12" of clear air space all around the unit.

5. Unit is operating in a room that has an ambient air temperature at floor level, of between 40 -60 degrees F. Most dehumidifiers don't work well between those temperatures. Raise the unit up off the floor on to something sturdy enough for the weight of the dehumidifier when the bucket is full.

The above are the top 5 things that can cause a dehumidifier not to work properly. Fortunately, none of the solutions require any major repair to the unit.

Hope this helped you to further troubleshoot and solve the problem.

Do these humidifiers have a filter that needs cleaning?


Yes, they do. The filter is located behind the louvers on the front. To remove it for cleaning, grasp the Filter Handle on the right side of the unit, on the same level as the louvers and pull it out. Clean the filter with a vacuum cleaner or luke warm water and a mild detergent. Thoroughly dry the filter before reinserting it.

If you have misplaced your Owner's Manual, I have included a link to it, that you can download and print for future reference. http://www.haieramerica.com/en/asset/product/4ba7175e54 Read over it and follow the suggested Routine Maintenance Guide.

Hope this helped you. Please let me know. Thanks.

LG dehumidifier developing ice


First you would need to clean the filter. LG recommends cleaning the filter every 2 weeks on their dehumidifiers. The second thing you need to do is clean the coils periodically. On this dehumidifier it should include a brush for cleaning the coils. It is located on the top of the bucket. To access the coils the following needs to be done:

1.) Unplug the unit from power
2.) Remove the bucket and also the air filter
3.) Remove the front pannel by removing the 2 lower screws and depressing the tabs.
4.) Once the panel is removed you will see the coils. You need to clean them with the brush. Go in an up and down motion to remove the dirt and dust.

Now use the reverse steps to put it back together. If your dehumidifier runs often I recommend you clean the coils about every 3 to 4 months. This is a common problem on alot of dehumidifiers and people think their dehumidifier is broken. Most of the time the coils are just dirty which causes the water to stay between them and freeze. Keep me posted. Also if you found this response helpful, please rate this solution when you get a chance. Thanks - Tech101
