    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.

    I have a LAD704DUL frigidaire dehumidifier that will not shut off after being shut off, and not until the plug is pulled. Is this worth getting fixed


    Dear Peter Nicolle,

    according to the user manual the dehumidifier will not stop running for the following 5 reasons:

    • Windows or doors near dehumidifier are open to outdoors.
    • Area to be dehumidified is too large.
    • Air movement through dehumidifier is blocked.
    • Dehumidifier has been installed or restarted recently.
    • Dehumidifier is in the CONTINUOUS mode.
    You can find more information on the user manual on page 9 under the category DEHUMIDIFIER RUNS TOO MUCH.

    Why does Frigidaire dehumidifier LAD704DUL has ice on the coils?


    Hello Friend, thank you for your question!

    I see that you have frost accumulating on the coils of your Frigidaire dehumidifier, LAD704DUL. Typically frost appears on coils either because your dehumidifier has been turned on recently or the room temperature is too low. Sometimes this is normal due to refrigerant rushing through the coils and usually it disappears within 60 minutes. However, if your dehumidifier is not removing moisture, then at this point your dehumidifier may possibly been experiencing a sealed system issue. Is your appliance still in warranty? If so, you might want to reach out directly to the manufacturer to determine the coverage on your dehumidifier and the procedures to any potential remedy in that regard. Hope this helps! - Z

    I cant change humidity levels


    Hi Ra Ma,
    After you have set the desired humidity, the readout will display the actual room humidity. It has a built in hygrometer which will be on the display while it is running.
    You change it and it shows the actual levels.

    See page 5 on manual.

    I have a 2 year old Frigidaire dehumidifier model FDM7051 and this summer when I turned it on it runs continuously with the fan moving normal amounts of air. The air filter and coils are clean and I have...


    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.

    Check the float valve in the top of the bucket. It may be stuck in the UP position. If that the case, jiggle the float valve arm to get it to return to the DOWN position. That should solve the problem.
