If on the top you mean only at the top of the cooling or condensing coil the machine could be low on refrigerant.

    So what do we DO about insufficient refrigerant?!? You left us with a very partial answer!

Check the filter and the coils behind the filter for dirt and clean as needed.

The unit is not drawing water from the air


Mary,
There is a recall on Whirlpool dehumidifiers that may cover your unit, the website lists serial numbers of units on the recall list.
Dehumidifier Recall FAQs
I assume from your question that at least the fan is running. There are many reasons why a dehumidifier is not removing water from the air. Most likely is accumulation of dust and pet hair that restricts the air flow. If you can, unplug it, take off the covers and vacuum out all the dirt from the evaporator and condenser (little radiator like parts). This website has some good blow up pictures of how it is put together and part nomenclature:
WHIRLPOOL DEHUMIDIFIER Parts Model AD25J3 SearsPartsDirect
If the air flow is restricted, the compressor has to work harder to the point that the overload gets tripped. It may or may not be resettable; it is part #10 in the diagram on this page:
http www searspartsdirect com Whirlpool Dehumidifier Parts Model AD25J3...
If you do take the covers off, check that the fan turns freely and you may want to add a drop of oil to each end of the motor if there is a place to oil it. Light oil like sewing machine oil or light engine oil will do.
You cannot really tell if the compressor is working with all of the covers on; and I cannot recommend plugging it in with covers removed because there may be open electrical connections that you do not want to touch. However if the compressor is running, the outlet tube will get hot; that is the one that goes to the condenser [radiator like bundle of tubes nearest the fan] [it may get too hot to touch]. The evaporator [bundle of tubes farthest from the fan] should start to get cold where the tiny little tube from the condenser joins. If neither is happening and you are sure the compressor is running, it is out of refrigerant [freon] and may or may not be worth fixing. If the evaporator ices up [gets covered with frost] it may be low on refrigerant indicating a leak; again it may not be worth fixing.

I purchased this dehumidifier three years ago. It has been working fine up until about two weeks ago. I have the humidity setting at 40%. It is located in my basement which is not very damp. It now runs...


Jeanne, unless your unit is what's called a "Low Temperature" unit (these are designed for basement application) , that may be the problem. In addition, the air intake filter may need to be removed & cleaned.

If yours is not a Low Temp model, raising it up of the floor onto a sturdy table or counter top that can handle the weight of the unit and a full bucket of water, may solve the problem. The reason for this is in a basement, the air temp at floor level is colder than at shoulder level. Non Low temp units struggle to operate at temperatures below 65 degrees. Raising the unit up off the floor onto a sturdy table or counter top, that is strong enough to handle the weight of the unit, plus a full bucket of water, will usually resolve the problem.

I hope this information helped you and thanks for choosing FixYa.

2 years old unit would not extract moisture from the air. Had another unit on which was working ok. How could I fix this problem?


There are 5 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. However, running to dehumidifiers in the same proximity may be the problem. ON is doing the lion's share of humidity extraction, leaving little or nothing for the other to extract.

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
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.

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

Kenmore dehumidifier 54701 runs but very little water accumulates in tank. It is 3 years old. It used to take out at least a tank of water every day.

I have a Goldstar 305 unit and have been very happy with it for 4 or 5 years. Three days ago I noticed it was running very loudly and for much longer than it usually takes to fill the bucket. The bucket...


The problem you're having sound like the drain tubing to the bucket is partially clogged. But, it is resolvable. Here's what you'll need to do.

Turn the unit OFF & unplug it from the wall. Remove the bucket and at the inside top of the bucket holder, you will see a hole or a tube that drains water into the bucket.

Using an 18" long plastic Zip Tie or something similar (NO wire coat hangers, though) that is appropriately sized to fit in the drain hole or tube. Carefully insert the Zip Tie and work it in, until you reach a bend in the tubing. You will need to gingerly work it past this bend, until it either bottoms out or your run out of usable Zip Tie. Then, slowly remove the Zip Tie while rotating (twisting) it. This will dislodge any clogs. Once you start nearing the end of the inserted tip, be prepared for some water to follow.

After completing the above, reinstall the bucket, making sure that it fits "squarely" from top to bottom into the bucket holder. The bottom should not tilt down at all. Plug the unit in, and turn ON the Master ON/OFF Switch. Lower the humidity extraction level to 32 -35%. If you don't have an LED screen on your control panel, set the manual control to Maximum.

One other thing that you want to do on a regular basis. That's remove and clean the air intake filter, if necessary. Be sure to turn the unit OFF and unplug it, before removing the filter.

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

Fan works but little water is removed


make sure your grille/radiator/filter/fan, etc is clear of dust/lint, etc. does the compressor run? if not check the thermocouple/temp sensor

The dehumidifier runs a long time & does not remove much 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. If this is blocked with fluff then no moist air will get to the cold pipes, so little or no water will be extracted.

Hope this helps. If this "fixes ya", I'd appreciate a rating for my reply, If not, please delay the rating and add a comment with any extra info you have and I will try to think of something else.

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.
