If nothing at all works, its most likely a control (switch or stat). Be very careful if you try jumping them. Line voltage is dangerous if your not sure of what your doing.

SOURCE: Dehumidifier -- LG LHD45EL

If everything is clean on the coils and the filter is clean it should work. I would contact LG because they have a 5 year warranty on these dehumidifiers. Make sure that you have your reciept. Usually what they will do is locate a shop near you and it can be serviced there. LG will pay the bill. Or if there is no local shop they will send you a service tag for your old unit and ship you a replacement unit. Contact LG and explain this problem to you. Everything should be covered under warranty still.

Good luck - Tech101

SOURCE: Kenmore Dehumidifier Won't Power On - No Lights, No Action

It sounds as if this may have electronic controls on it. If so, the problem could be related to too low of an ambient temperature or too low humidity in the air. If this design has a temperature sensor built into it, you may be experiencing "hibernation mode", where the unit will appear to be dead, when it is actually awaiting the proper temperature to employ itself.
The following statement is a parameter for all dehumidifiers and some of the control issues may vary, but the theory is the same.

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.

Thank you for your allowing me to advise you on this issue.

SOURCE: Ice on dehumidifier

A dehumidifier works by cooling the metal pipes on the back of the unit to create condensation (water vapor in the air). This then drips into the collector bucket. If the unit runs too long the cooling tubes can get too cold and freeze the condesing water vapor. Unplug the dehumidifier and let the ice melt, when u turn it back on, turn it down, it may be up too high. If you find this solution helpful please rate it.

SOURCE: kenmore dehumidifier runs but won't collect water

Hi,
If you haven't done so already, try removing and cleaning the inlet filter screen which is almost certainly just behing the inlet grille. It may slide upwards out of the casing or downwards unto the bucket area. If this is blocked with fluff then no moist air will get to the cold pipes, so little or no water will be extracted. There's also a chance that the humidity sensor is clogged with fluff, so fooling the system into thinking the room is pretty dry, in which case the compressor will probably not run.
A running compressor can usually be detected as a deep throbbing from the machine. If it is running, but not cooling the pipes behind the intake grille, then you may have lost the refrigerant from the system via a leak. If the air coming out of the machine is warm (caused by the compressor running) but there is no water produced this may be the cause.

Explore along these lines and let me know what you find.
Cheers, D

SOURCE: The dehumidifier is running but very little water

I have the same problem, just started it after not using it for the winter and it runs and runs and no water. I believe the coolant has leaked from the sealed system and there is nothing you can do. I've had it for 1 year and it has a 5 year warranty. I know from experience, this is the 3rd dehumidifier that I have had this problem with, all different brands. Call for service, I am betting you have not had it very long.

Runs for a few minutes then shuts off, easy fix. First, remove water catcher and slide filter out and clean it. Then find the two screws that hold on the front panel remove front panel. Make sure the unit is un-plugged. The humidity control dial has two wires connected to it. clip the inner wire. This will keep the unit on full. You could replace the humidity control dial, but why bother?

Dehumidifier still runs, blows air, various controls all seem to respond. Just doesn't dehumidify. If I need to take it in for repair, can you recommend someone in Northern VA area? Thanks.


It may not need repair as, there are 5 basic, yet solvable reasons for what you described. Please pay particular attention to numbers 1 & 2..

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have an analog unit
(no LED screen), turn the humidity extraction 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 troubleshoot & solve the problem without have to make any repairs.
Thanks for choosing FixYa.

Ice is forming on the top of the unit, it is running but not very much water is collecting


Ice will often form if the humidity level is high or the air intake filter needs cleaning. If it's because of high humidity or being used in a basement, the unit may appear to still be running, but it's usually just the fan and it's going thru a defrost cycle.

If you check the filter, be sure to turn the Master ON/OFF Switch OFF and unplug the unit. Remove the filter and clean if necessary. If you wash the filter, use warm water and dish washing liquid. Rinse thoroughly and allow to dry completely, before reinstalling it. DO NOT run the dehumidifier without the filter installed.

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

Will not defrost. Frosts up but not defrost properly.


The air intake filter may need cleaning. If it's dirty or clogged the unit has to strain to keep up. Also, if you're operating it in an area that's below 40 degrees, they have a tendency to frost over.

Turn the Master ON/OFF Control to OFF and unplug the unit. Allow it to thoroughly thaw. After it has thawed, remove the filter and clean it if necessary. It's also a good idea to access the refrigerant coils to wipe and clean them. After they're clean and dry, a light coating of WD40 would be an advantage.
Then, reassemble the humidifier's cabinet, plug it in and turn the Master ON/OFF Switch to ON. Set your humidity level about mid range (45%) and allow the unit to run for at least 1/2 hour before raising or lowering the humidity range.

Routine maintenance is important and will usually solve the problem. I hope that's the case for your dehumidifier.

Unit runs but doesn't collect water and there is a lot of water in the basement. Have had dehumidifier for two weeks and was working well before.


Keep in mind, that a dehumidifier only draws humidity from the air, if the level of humidity is higher than what the controls are set on. For instance, if you have the dehumidifier set on 65 to 70%, that's a high level of humidity to maintain in a house. If you have it set for 35 or 45%, that's a low level of humidity to maintain in a house. Which, generally is what you want to maintain in the hot, humid summer months. Also, it's not uncommon on some dehumidifiers for the fan to almost run constantly. It's designed to keep the air moving, in a effort to detect when the humidity level rises.

Also, a dirty air intake filter makes the unit strain to keep up and can't take in moisture as it should. So, if you haven't cleaned the filter no is the time to check and clean it. And while your at it, clean the cooling coils too. Since it sounds like this unit has been working hard for 2 weeks.

The easiest and best way to test a dehumidifier at home, to see if it's working properly. Is to place it in the bathroom and turn the shower ON and don't operate the bathroom's exhaust fan. Set the humidity level low (45%), turn the unit ON and close the door when you leave. Wait 15 to 25 minutes and check the water collection bucket. If there's water in it, it's working as it should.

For more information on the proper operation of a dehumidifier, go to the Tips section of Fixya and look up "Taking the confusion out operating a dehumidifier".

Hope all this helps you troubleshoot and solve the problem. Please let me know. Thanks.

Motor runs, but dehumidifier does not collect water


Keep in mind, that a dehumidifier only draws humidity from the air, if the level of humidity is higher than what the controls are set on. The fan running, may be the automatic defrost cycle, that defrost the coils, if they become frosted over. The defrost cycle, depending on the unit and how is was designed, can last any where from 15 minutes up to 45 minutes.

Also, a dirty air intake filter makes the unit strain to keep up and can't take in moisture as it should. So, if you haven't cleaned the filter on a regular basis, not is the time to do so. And while your at it, clean the cooling coils too.

Of our three 54501 Kenmore dehumidifiers, none produced water after two - three weeks. They run but no humidity is drawn out of the air.

If you have it set for 35 or 45%, that's a low level of humidity to maintain in a house. Which, generally is what you want to maintain in the hot, humid summer months. I find it uncanny, that all 3 units are not collecting any water. So, it may simply be the case, that the humidity level on each unit is improperly set.

Hello,

First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again. Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running.

If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils. If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue. This situation will have to be addressed by a qualified technician.

Take care.

Unit runs but doesn't pull humidity out of room, filter clean


Possibly lost refrigerant from system- check warm air is coming out of machine. Otherwise it could be dirty filters, and not getting enough air over evaporating coil. Other than this, replacing parts is usually more expensive than buying a new dehumidifier :(

Dehumidifier does not fill up with water anymore


If your dehumidifier doesn't seem to run often but the humidity in the room is high, try adjusting the humidistat control on the dehumidifier to a dryer setting. If the dehumidifier seems to run constantly, but there's little or no water in the container, there may be a problem in the refrigeration system. Try cleaning the unit. If that doesn't work, you can't repair the refrigeration system yourself, you need a qualified appliance repair technician to do that.
