Question about Dehumidifiers

1 Answer

Whirlpool dehumdifier not functioning

It isn't drawing any humidity out of the air at all. The resevoir tank has cobwebs in it, and the hose we have connected to the tank is also dry as a bone, yet the dehumidifier runs nearly 24 hours a day. We have had it for about 3 years.

There are 5 basic, but 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%.

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 Humid-i-stat 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.

No all of the above may apply to your circumstance, but keep them in mind for non water collecting problem. Thanks for choosing FixYa.

Dehumidifier is running the filter is clean but its not pulling moisture out of the air. Nothing is coming from the hose that is attached


What is the setting? Your machine is controlled by a 'humi-stat'. It comes on when the machine detects the % moisture in the air is more than that number you selected on the machine ... usually a number between 45 and 100 %. If your machine turned itself on, there must be some humidity in the air (50% is the ideal, BTW). The machine works based on natural laws that cannot be violated. Think Dew Point - think hot air going over cold surface. Think a glass of ice water sitting in the sun on a hot humid day. Think cold can of soda on a hot day. ... and so forth.

The filter would have little effect on the actual operation. The filter is to keep the dirt off the cold, normally wet coils. Were it not for the filter, the coils would become clogged with dirt and there would be no air movement over them to remove the water. Still, the filter doesn't actually have a big impact on the mechanical operation of the device - You have done well, keep it clean and in place.

So, you know there is humidity in the air that exceeds the setting on your machine, right? If there is water in the air and the machine is operating normally, there will be water on the coil that drip into the bucket and into the hose, into the drain ... ultimately back to the sea, full circle.

If it is not wet, perhaps you have set the humistat to a number where there is little water to remove - it may be removing that tiny bit of water and because it is so dry in your space, the water may be going right back into the air. Air does want a certain amount of water in it. Too little and you will not be comfortable, furniture will dry out - crack. Your nose will dry out - you will be very uncomfortable - static electricity will be prevelant - you will get shocked as you move about the space. Think about cold dry winters when people actually put water back into the air for their comfort with a HUMIDIFIER. During such conditions, the water (in the tank of the device) just disappears into the air.

So what to do. I suggest you review the setting on your machine. Set it to 50%. Get a device to measure the humidity such as one found on this page: http://www.calright.com/products/gr_id/64/?gclid=COGVyqD14KoCFcl95QodTEOj6g. Of course, it would be nice if you purchased the device from a FixYa.com advertiser - look around this answer for their advertisement.

I would run a fan in the space to circulate the air so the dehumidifier has the best opportunity to measure all the air, and treat it. If the machine continues to not produce any results (water) you may have a faulty humi-stat or your device may have a leak - thus low or no freon or other agent inside - to make cool coils for the warmer, humidity laden air to flow over thus causing the humidity to give up its hold and condense on the coils, fall to the bucket, etc.

I hope this discussion helps you with your trouble. Thank you for your interest in FixYa.com

One-year old LG humidifier (LD450EAL) runs but no water is being extracted from the air - the hose outlet is dry. The hose is connected properly, and the compressor sounds like it's running, not just...


Alan, it may simply be a case of several things, that can easily corrected at home.

1. The Humidity Extraction Level is set to High. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Remove, inspect the filter and clean if necessary. It it's a
Washable Filter, allow it to thoroughly dry before reinstalling it.

3. Obstructed Air Flow. A minimum of 12" to 18" clear air around the entire unit, must be
maintained.

4. The ambient air temperature at floor level is between 40 - 60 degrees F. This is particularly true in
basement applications. The air temp at floor level is colder than the air temp at shoulder level.
Dehumidifiers don't work well in that temperature range (Unless, it's a Low Temp model). Raise
the unit up off the floor on to a sturdy table, counter top, etc, that can handle the weight of the
unit, plus a full tank of water.

If you troubleshoot the 4 things listed above, it may quickly solve the problem. Please let me know. Thanks.

Hello, I need a dehumidifier of 50pint or more that stop when the humidity level is reach and will restart when is too high. I look for a lot of brand and model and I cannot find one thanks for your...


The fifty pint capacity might be a challenge ... think about this ... 6 + gallon tank @ 7+ pounds per gallon ... 42 pounds of water to drag from the dehumidifier to the drain? Who is going to do that?

All dehumidifiers run at some % of humidity (via Humistat), (like you are asking about) i.e. come on at some % above the setting and go off when the setting is reached. I suggest you find one that has a standard one or two gallon tank that also features a hose connection in the tank. Run the hose from the tank to the floor drain in your basement or a drain near what ever room you are trying to dry out. When you connect the hose --- you will have to put a hole into the fitting on the tank for water to flow. The idea of the tank is that the machine will run on the setting until the tank fills up ... at which time the tank full switch will not allow the machine to run again until you dump the water (and you want to drag a 6+ gallon tank, 42+ pounds, around?) . If there is a hose attached, the tank never fills up.

Some dehumidifiers feature a pump to which will pump the water to a near-by drain. You may be able to rig such a setup yourself using a small pump like a fish pond pump or similar.

You may want to consider using two dehumidifiers (with or without hoses) rather than one BIG machine. I run two machines from a major USA retailer (one in each end of the basement) and they run into the near by sump and the system works fine @ my house.Thanks for your

Thanks for your question @ FixYa.com

This summer I have ice build up on top of the unit. I have a drain hose so the bucket is not full. I have cleaned the air filter. I have also removed the front grill and used a fine brush to remove dust...


Hi,

The coils you see on the back of your dehumidifier are the evaporator. When the unit runs, the coils get very cold. As the fan draws the room air over the coils, the humidity in the air condenses out of the air onto the cold coils. But, if the temperature of the air the fan draws over the coils is too cool, the humidity that condenses out of the air freezes on the coils.

To remedy this problem, you can try any of these:
Warm up the room the dehumidifier is in.

Put the dehumidifier on a sturdy table (the room air is coolest near the ground).

Turn the unit off until the room warms up.

Take care.

Dehumidifier doesn't draw in water (humidity).


It may be too cool in the basement for it to work. Mine doesn't work if its 67 or below. Take it upstairs and see if it works there, where it is warmer.
