My FDD50J2 is not dehumidifying. The fan runs but the unit does not remove amy moisture from the air. It has run for several days. I have adjusted the control button to the high, low, and between positions with no affect. My basement air is definitely becoming humid, the temperature approximately 70 degrees. I do not find DEHUMIDIFYER EXPERT from my choices below. Can you please assist? Thank you. Craig Muirhead cmuirhead@ameritech.net

Hi..
The evaporator coils on the front of the air conditioner get very cold during normal operation of the air conditioner. As the warm moist air in the room comes in contact with the cold evaporator the moisture in the air condenses out of the air and attaches to the evaporator coil. As more and more moisture condenses the water begins to drip down into the base of the air conditioner where it is evaporated to the outside of the house.... so the problem might be in ur evaporator coil.. try replacing the coil if u are an expert or else with the help of technician try to fix it...

thank u
rate me!!!

     Is the thermostat knob turned to the proper setting? Is the compressor motor running? The compressor is a football-sized case with no apparent moving parts. It is located inside the air conditioner at the center. Is it humming or making any kind of continuous noise or causing the lights to dim? If it is making a continuous noise, and your air conditioner is still not cooling at all, there may be a serious problem with one or more of these areas:
    Compressor
    Condenser
    Evaporator


    These items are not user serviceable. You will need to contact a qualified appliance repair technician to repair these components.

    If the compressor is not running but you do have power to the air conditioner there may be a problem in one or more of these areas:

    Compressor
    Overload and/or relay
    Thermostat (Open thermostat)
    Burnt wiring
    Bad selector switch
    Capacitor..
    hope this will solve ur problem.. i have given enough solutions..
    thank u

Dehumidifyer not dehumidifying


The dehumidifier needs to have the control set correctly and the fan and the compressor to run in order to remove moisture from the air. The fan pulls the warm, moist air over a cold coil where the moisture condenses into water. Cool, dry air is expelled from one side and warm dry air from the other.
If the unit is low on refrigereant, the compressor will not run - nor remove moisture. Likewise, the control must be set right, too. Finally, most unit rely on a float switch or a tank switch to determine if the tank is full or present. If the float switch or tank switch is jammed due to tank position, it may prevent the unit from running. Remove & carefully reinstall the tank to see it that solves the problem.
Good luck!

Tip

Dehumidifier VS. Air conditioner


A dehumidifier is basically the same thing as an air conditioner but both coils (condenser and evaporator) are in the same unit meaning a dehumidifier exhaust warm air in the same room it is in. running a dehumidifier would make an air conditioner run more because of the warm exhaust, when you run an air conditioner it acts like a dehumidifier and dries the air. As far as saving energy it all depends on the size of the AC and dehumidifier and the size of the room. If you want warm dry air, use a dehumidifier; if you want cool dry air run the AC but not both.
How do all these parts fit together to pull moisture from the air? It's fairly simple, but very effective:
  1. A fan collects air from the surrounding area and pulls it into the dehumidifier.
  2. As the air passes through, it comes into contact with the dehumidifier's cooled coils. These coils use condensation to pull moisture from the air. The collected moisture remains on the coils and drips into the dehumidifier's reservoir.
  3. The dehumidifier reheats the air and exhausts it back into the room.
A dehumidifier usually has a removable plastic bucket for are reservoir; most buckets also have a place where you can hook up a hose so the collected water can drain straight into a floor drain or pump. This frees you from having to remember to dump out the water. But don't worry too much about the reservoir overflowing -- most dehumidifiers also have an automatic shut-off. If you're using a dehumidifier in extremely moist conditions,however, or if you need to keep your dehumidifier on all the time, you should look into a unit with a built-in condensate pump, which regularly pumps water out of the unit's reservoir rather than simply relying on gravity to empty it as a hose does.

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 dehumidifer is not drawing any water, but the fan continues to run.


There are several reasons this may be happening. The 2 primary reasons are the humidity extraction level is set to high. Lower it to 35% . The lower the setting, the more moisture/humidity is extracted from the air. The higher the setting, the less if any moisture. humidity will be extracted from the air.
On most humidifiers the fan runs almost constantly while in operation. The idea is to continually move the air around and when the unit senses a rise in humidity, above what you have it set on, the compressor will turn ON to extract that humidity.

The 2nd thing that causes the problem is a dirty of clogged intake air filter. Which is easily solved by removing and cleaning the filter. Which should be done at least every 2 weeks, while the dehumidifier is in operation.

I said there were 2 reasons. Actually, there is a 3rd. Not enough clear air space all around the dehumidifier. A minimum of 12" should be maintained during operation.

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

HOW TO USE


Hello,

follow the instructions below on how to use your dehumidifier:

Prepare the room for the dehumidifier by vacuuming, dusting and cleaning the room. Be especially careful to have all mold removed prior to using the dehumidifier.
Plug in the dehumidifier into a grounded outlet.
Set the dehumidifier to high in order to remove excess moisture from the room.
Wait for the dehumidifier to run several cycles, removing all undesired moisture from the air. This may take days or even weeks in especially damp rooms.
Adjust the setting of the dehumidifier when the air has reached your desired comfort level. Make the setting one that will maintain the current conditions.
Good luck.

Does not dehumidify


Hello. I am here to help. Let me begin by saying that a dehumidifier only needs to be operated if the humidity in your home is too high. If the humidity is low, the humidifier will have to work really hard to try and remove water from it.

Here is an overview of how the dehumidifier is supposed to work:

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.

Most likely the fan motor is broke. I have seen several units with bad fan motors.
