Question about LG LD65EL Dehumidifier

1 Answer

Puts off a lot of heat

This unit seems to work fine, but it is like having a small electric heater going in the room. It pulls out the moisture really good, but we don't need more heat for the A/C to pull out when you live in South Florida

Re: Puts off a lot of heat

Additional heat from a dehumidifier should only be the electrical heat generated from the compressor. This is due to the fact that the cooling coil and condenser coil (hot bit) are normally located next to each other with a common airflow so the heat generated should be minimal. Hope this helps.

My Kenmore dehumidifier is set for 65 the display constantly reads 90 and is always running and collecting water the unit never turns off and the display number always stays at 90. What is wrong?

wow it seems you really have a lot of moisture , 1st i suggest you find and seal location of water entry second you might have to consider getting a second unit or a larger unit to work as your primary and save smaller unit for use as a back up
they are rated in Pints per hour the bigger the number the more water they pull out of air sounds as if your gonna need a 60 PPH unit or larger

Btw : 70%rh is considered the "normal" of the avg home
yours at 90 % rh is unhealthy for humans and will promote respatory mold growth and all its complications unit setting of 65% is telling me that unit is too small to handle amount of water you have

My dehumidier blows very hot air while working. Makes it hotter than it was before starting. Like a furnace.

It is normal for a dehumidifier to discharge warm air. A dehumidifier is really an air conditioner - a fan blows humid room air across a cold fin coil that causes the moisture to condense on it and drip into a container - thus cooling AND dehumidifying the air. The cool air is blown over the warm coil and discharged out the back. A dehumidifier WILL normally increase the temperature of the room it is in.
You can do the same thing with sitting an A/C unit on a stool in a room. Room air will be drawn in, cold air will come out the front, hot air out the back and water will drip on the floor. And, the room will get hotter, due to what is called "heat of compression" even though you're running an A/C unit.

I think you are asking about a portable air conditioner, not a de-humidifier. With that assumed, the answer is, NO - that is not a good idea. The exhaust tube is for getting rid of the heat that you have pulled from the room you are cooling, plus the extra heat that the device itself creates. This is a considerable amount of heat, which will quickly heat up the closet and leak back into the room you are trying to cool. If the closet it tightly sealed, the unit will not be able to push the air through the tube, and the unit itself will overheat. The result will be that you will be buying electricity to actually RAISE the temperature of the room you are trying to cool.

The room my dehumidifier is in stays 80 degrees when the Haier is runnng. why

A dehumidfier works by heat, so it puts out a lot of heat that is exhausted back into the room. An air conditioner works with heat also and it also takes the humidity out of the air, BUT it exhaust to the outside.

Ice forms on the coils. Would wet clothing hung in the area contribute to this problem? The temperature of the area is in the high 50's - 60's.

Yes. Wet clothing would act to put Humidity in the air. think of the air as a sponge the more you heat the air the more the air will take moisture out of its surrondings. The more you cool the air the less moisture it can hold.
a Dehumidifier is a reverse refrigrator.. Air is forced over cool coils and the moisture forms and freezes on the coils (ice). The unit turns off and the coil and ice takes heat up from the surrounding area (makes room colder;Clothing takes longer to dry; The temperature in that room should be were people reside 70-80 degrees). the ice melts and water drips into a holding container which you dump periodically. Solution: 1. remove wet clothing or 2. raise temperature in room. 3. put a space heater in that room instead of Dehumidifier

We bought a ADEH 50 LNL1 Serial 106143 this summer. It does a great job at removing water from our basement,needing emptied every 24-36 hrs. However it is always so hot in whatever room we set it that...

Unfortunately see a dehumidifier puts the heat back into the room... it does not remove any heat...but... the heat from the fan motor and the compressor is added to the room... thus the heating that you are noticing...

Sorry I cannot give better news... :-(

I have a Whirlpool dehumidifier model AD050SG0, is it supposed to blow hot air out of the back of the unit?

A dehumidifier is a 'de-tuned' air conditioner. Its job is to remove some of the heat from the air, causing a temperature differential which in turn should make the warm air give up some of its moisture ... just like a AC unit.

To understand the operation, you must accept that you cannot cool anything ... you must remove the heat from it. The heat (energy) must go somewhere ... in the case of a dehumidifier, it goes back into the room. Oh yes, also contributing to the heat is the electric components you are running ... the control boards, the compressor and the fan ... all use power and thus, give off heat.

Should there be heat coming out of the unit? ... yes, if it is running. Don't get mad ... these are things you probably learned in 6th grade science class - relative humidity - heat differential - properties of energy - etc.

Thanks for your question at

We inherited a 655e. It seems to function properly, at least it responds to controls the way it should. It does dry the air, the bucket will slowly fill, but the unit blows warm or hot air. I'm new to this...

Dehumidifiers are designed to remove the moisture from the air not to cool. Unfortunately, the way they remove this moisture is to reheat the air to further dry it after it releases its moisture. Basically, the room temperature humid air enters the dehumidifier where it is cooled to its dew point which results in its releasing its moisture. This dried air is then heated by the combination of latent heat of condensation, which is a natural result of the process, and by circulating through the condenser where heat is exchanged from it to the air. The result is the air going back into the room will be slightly warmer than it was going in, usually around 2 to 5 degrees.

It seems as if the unit makes the room warmer. Is this normal?

Yes the heat is a byproduct of the compressor running....there will be a slight overall heat gain...this is very normal and nothing to be concerned about....the dehumidifier passes the air over a cold coil to pull out the moisture but also discharges the heat into the the net result is heat gain in the amount of electrical energy the dehumidifier is using...

Kenmore 54501 turns on but nothing happens in my damp basement

A dehumidifier heats and cools the air to remove moisture. Most are like a small air cond. The Condenser coil is right in front of the evap.coil. So the compressor may not be coming on. Does it sound the same as before? It may be low on freon. You will have to get in there and listen and feel the lines at or near the compressor, Learn how to get down in there to the compressor. Run it for 10 Mins. unplug it, open it up, and feel the lines. Some lines should be or can be HOT to the touch. Some should be cool. The smaller the line the hotter it should be, and the compressor should be warm (to hot) to the touch. repost for more info.
