Question about Frigidaire 70-Pint 2-Speed Dehumidifier ENERGY STAR LAD704DUL

Open Question

Dehumidifier was in storage for about a year. Reactivated it in our new house. Removes water fine but fan seems to run a lot after the humidity setting has been reached. At the old place, the fan didn't do that. I have vacuumed the grill and cleaned the filter. Don't know what else to do.

Don, unless your dehumidifier is a Low temperature model, that very well may be the problem.
The air temp in a basement at floor level is colder than that chest level. Dehumidifiers don't work well at temperatures at 40 degrees F or less. Raising the unit up off the floor on to a sturdy table, counter top, etc, that is strong enough to handle it's weight, plus a full tank of water, will generally solve the problem. The higher up you can safely put it, the better. Also, lower the humidity extraction level to 35%. As 50% is just not low enough in a basement application.

Hope this helps you to solve the problem.

    If you have a dehumidifier that is not producing any water then you are wondering what you need to do to get this thing to work for you. In some cases you may be able to do something and in other situations there may be nothing that you can do.

    If you do not hear the compressor running and the unit says that the humidity in the room is higher then the setting, then you have a problem with your dehumidifier.

    A few things that can cause this are:

    The circuit board relay has gone bad...replacement of this board will often cost more then a new unit. This also is a very common problem with many dehumidification units.

    The compressor has failed...if you hear a buzz for a few seconds, every few minutes, then you have a bad compressor or at least bad start components on the compressor. Either way it again is a costly repair.

    If the compressor is running and the coils are not getting cold then you have a refrigeration system leak. Recharging or fixing these units is very difficult and is another costly venture compared to the price of a new dehumidifier.

    If the compressor is running but the fan is not, this also will cause low water production and continual freezing of the coil.

    If the compressor and the fan are running but the coil is totally blocked then you will get no water production. Air needs to be continually moved over the cold coil to get the water out of the air.

    If nothing is running, then you may also have a control board failure. Or the humidity sensor or humidistat has gone bad which tells the machine to run. If the sensor says that the humidity is low enough then it will never run.

    Also if nothing is running check the float switch or the bucket switch. Many of these switches are very touchy and if you do not have the bucket in place just exactly right it will not trip the switch to allow the unit to run. These switches often are more fragile then they should be and break easily. The good thing is that when available they are easy to replace and relatively inexpensive.

    There are some parts available for a few brands, but with the prices for most of the parts that you can replace running anywhere from 40.00 - 80.00 dollars, replacement parts with labor to install them, makes a repair more then the few hundred dollar cost of many of these dehumidifiers.

    As you can see there are quite a few things that can cause your dehumidifier not to work. Systematically go through the list and eliminate things to get to the bottom of the issue causing your problem and then decide if it is worth spending the money to try to fix the old unit. Only you can make that decision.

    We can hear the fan running and then the compressor, but little to not water produced; sometimes we can hear it click on and then off; the fan seems to be running a lot...


    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.

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

    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.

    A challenge dehumidifier not collecting water


    If the room tempature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
    I out mine over the floor drain.
    Turn off and it will defost over night.
    Only specially made dehumidifers work below a room temo of 60 degrees (the temp of a basement in winter).
    Does it need to be running? A digital humidity sensot from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

    Dehumidifier does not collect water.


    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.

    Hope that helps! Should you have any further questions, please feel free to post them here.

    Running but not collecting water...


    Dehumidifiers have only a few components, and operate on the same principle as a refrigerator, freezer, or air-conditioner.
    Components Residential dehumidifiers have a cooling system made up of these primary components:

    • The compressor is the quiet motor (engine) of the cooling system. It's the black, football-size component at the bottom of your dehumidifier. The compressor runs as long as the dehumidifier humidistat (the humidity-sensor) calls for a reduction in the humidity.

    • The condenser is a series of finned tubes, similar to a radiator. It's usually near the circulating fan.

    • The evaporator is located near the back of the dehumidifier, right above the water-collection container. It also resembles a radiator or a coiled-up set of tubes. When the dehumidifier's humidistat senses increased humidity, it cycles on, which starts the compressor and circulating fan.

    • The circulating fan circulates the air over the evaporator and condenser coils.

    Principle When the unit runs, the circulating fan and compressor also run. The fan continually draws room air over the evaporator coils, which are cold, and then over the condenser coils, which are warm. Because the evaporator coils are cold, the moisture in the room collects on them--just as the outside of a glass of icy liquid "sweats" on a warm, humid day. When the moisture on the coils increases, it drips off of the coils into the collection container.

    The air then flows over the warm condenser coils and out into the room. This process removes water from the air and, because of the heat from the fan motor and compressor motor, the exiting air is somewhat warmer, as well as dryer.

    Unit runs a lot. Doesn't condense much water. Sometimes fan runs alone, sometimes compressor runs alone.


    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.
