So far, you've completed all the right tings, that I would have suggested. Now, take a look at the humidity setting on the dehumidifier. If it's set high (above 65%) there's not much chance that the unit will collect any humidity. It simply is just maintaining what it's set on. Lowering the setting to 35% will have a much better affect in removing the humidity/moisture.

There is an in home test you can do, to make sure the unit is working properly. Place the dehumidifier in the center of a bathroom and turn the shower ON hot enough to generate steam. Turn the humidifier ON and Set the level at 35%. Do Not turn the bathroom's exhaust fan ON or leave a window open in the bathroom. As you exit the bathroom, close the door and wait 15 to 20 minutes before returning. After entering the bathroom, turn the shower OFF and allow the unit to run for 5 more minutes. Then check the bucket for signs of water. If you find any, the unit is working as it should. Also. the dehumidifier, when in operation should have a minimum of 2 feet of clear air space around it. The fans on many units run almost constantly, to recirculate the air and if any increase in humidity is sensed, the compressor will turn ON. This is particularly true, if you operate it in continuous mode, rather than a timed mode. Also, be sure that all exterior doors and windows are closed when the unit is in operation.

If after doing the in home test, the bucket did not show any signs of water, either the humidity sensor has failed and needs to be replaced or the compressor needs to be recharged with refrigerant. If you don't feel comfortable trying to repair the unit yourself, the following is a link that will help you locate an authorized LG Repair Center in your area.

My Haier dehumidifier is harly removing any moisture from the air. It appears to run normally and I have cleaned the filter regularly. I've owned it about a year and it is model HD456E. It worked very...


If the evaporator coils behind the filters become too dirty condensation can be seriously ********. Check to see if the fins require any attention; they can be cleaned very carefully with a toothbrush and some water usually. If the buildup has become severe special chemicals need to be used on the unit- not something recommended the average person attempt. If the fins are clear check other airflow issues. Dehumidifiers generally need a period of 3 days to balance an area properly when functioning and sized appropriately.

After an hour, the refrigeration unit begins to freeze up. Condensation appears on top of the dehumidifier cabinet. I have eliminated all obstructions to air flow, including the filter. What can I do?


Hi,

The most common cause of frost and ice buildup on a dehumidifier is because the unit is operating in temperatures that are too cold. Many dehumidifiers are not equipped to run at temperatures below 65 degrees Fahrenheit.
To fix this problem, Position the dehumidifier in an area where there is at least one foot of clearance around the unit in order to allow for proper air circulation during its operation. Close all windows, doors and other outside openings to make sure your unit isn't attempting to remove moisture from areas outside of the immediate room. Determine the temperature of the room by checking a nearby thermostat or by using a hand-held thermometer.

Check the filter for dirt and buildup. Unplug the unit from the electrical source and check the filter by opening the filter compartment. If the filter is dirty, it will restrict airflow through the unit and lead to freezing. Soleus recommends lightly vacuuming the surface of the filter to remove dirt. The filter also can be washed in warm water if it is extremely dirty. Once clean, place the filter back in its compartment. Allow for the ice to melt and then restart your dehumidifier.

There are 5 basic, but solvable reasons for what you described.Numbers 1 & 2, you have already addressed.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

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
in basement applications. Raising the unit up off the floor, level
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 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.

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

Runs but doesn't work (no water accumulates)


It sounds like what you hear working is the fan. The unit also has a compressor; if the compressor is bad or the freon is gone, the fan will run but the coils wont cool to remove moisture from the air.

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.

You may have the humidity level set to high. If it's above 60%, that's what it's going to maintain, not remove. Set the humidity level on the lowest setting and try again. Whether you're using the hose or not, I don't suspect it's playing a role in it. Also, clean and reinstall the air intake filter.

Hope this helped you solve the problem. Please let me know. Thanks.

Dehumidifier frosts up


A dehumidifier will often frost up if room temperatures are colder than about 65 degrees F. If your room temperature isn't this cold, airflow to the unit may be restricted or blocked entirely. 1) Be sure the unit is set far enough from the wall so that airflow isn't restricted. 2) Clean the evaporator coils. To do this, unplug the dehumidifier and take off the outer cover. Allow excess moisture to evaporate from the coils. Then, using a brush attachment on a vacuum cleaner, remove all dust buildup. If necessary, cover the motor and electrical parts with plastic sheeting and spray with water.
