Question about LG LD40E Dehumidifier

1 Answer

Discharge air is HOT!! - not cool

After running my LG dehumidifier for 2 days (& removing 3 buckets of water) my basement temp is hotter than when I started. I was expecting the basement to be cooler & dryer - HELP !!! I made sure there are no obstructions to the air flow. The discharge air at the back of the dehumidifier is warm (possible caused from tthe fan being located above the compressor??)

A Dehumidifier will not cool your basement, just make it seem cooler at the same temp. Your dehumidifier may be undersized even for that purpose.

You need an AC outlet of a central AC in your basement, or a window unit if there are windows.

Warm air at discharge is normal.

SOURCE: Capacitor... discharge it?

The easiest way to is to short it out across the two terminals with an insulated screw driver. Then you use your meter to test it. http://www.repairfaq.org/sam/captest.htm#ctsaf

SOURCE: Water bucket - proper seating

Try re-seating the bucket. I have found some LG models that if not seated all of the way will sometimes keep running and think the bucket is not full even when it is. On the models that I have seen do it the problem is usually the left side of the bucket not engaging all of the way. When you reseat the bucket, feel where the bucket meets the dehumidifier on each side and make sure they are even. If one feels like it is sticking out further than the other and you cannot push it in any more pull the bucket out and try and reseat it again until both sides are flush with the dehumidifier. If you found this solution helpful please rate it.

Thanks - Tech101

SOURCE: Bucket fills up instead of water flowing out hose

There must be a blockage in the hose causing the water to back up and flow into the bucket. Try pushing a flexble peice of wire through the hose to unblock it.

SOURCE: water not draining in the bucket

have u checked the drain on it?? or if there is a filter might be dirty

SOURCE: Hi, I have an LG

Try to see if operating the float lever by hand can make it turn off the 'bucket full' message. Maybe use a rubber band or tape to keep it in the on position vs. the 'bucket full' off position.

Check to see if the bucket has to be inserted for the unit to operate, and if the bucket has a nozzle to hook a hose up to at the bottom. I have a dehumidifier of a different brand that has this feature that works with the bucket in, but with the drain nozzle on the bucket connected to a plastic tube that leads to a drain for continuous operation without having to empty the bucket.

How is your hose attached to the unit if it isn't attached to the bucket?

Good luck on this repair.

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.

The dehumidifier is getting cold condensation on the top outside of the unit and no water in the bucket. Model BGD-510A. I cleaned the filter and the coils and still have this problem.


Kathryn, if you are operating it in a basement application, the problem is that air temperature at floor level, is colder than at shoulder level. Dehumidifiers struggle to work at temperatures between 40 & 65 degrees F (Unless they are Low Temp model designed for basement applications). And will ice up at times. 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 bucket of water, will usually resolve the problem.

If it's not a basement application, try lowering the humidity extraction level to 35%. In you have an analog unit, turn the control knob to Maximum.

I hope this helps you and thanks for choosing FixYa.

When the dehumidifier runs it forms ice on the top of the unit and does not collect much water in the bottom.


The problem you described can be caused by 3 things:

1. The air intake filter is dirty or clogged and needs to be removed and cleaned.

2. The cooling coils are dirty and need to be cleaned. Turn the unit OFF & unplug it before attempting
to clean the coils with warm water and mild dish washing liquid. Then rinse and wipe dry. A light
coating of WD40 will help them stay clean.

3. The dehumidifier is being operated in a basement, where the air temperature at floor level is
below 65 degrees. When this happens dehumidifiers struggle at temps below 65 degrees F
unless it its a Low Temp model, designed for basement applications. Raising the unit up off
the floor onto a sturdy table or counter top, that can hold the weight of the unit, plus a full tank
of water, will generally resolve this problem.

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

Lg dehumidifier lhd30 normally removes an almost full bucket of water from my basement every 24 hours. Now in July it stopped doing so. I get about an inch of water per day now. If i turn the control down...


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%. If you have a mechanical unit,
uni, set the control knob to Maximum.

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 may have 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 helped you to troubleshoot & solve the problem.

Basement smells musty, fan won't stay on continuous


Barbara, are you running the unit in a continuous mode (i.e Using a hose to drain the unit)? Or is the water draining into the water collection bucket?

If you are not using a hose for continual drainage, the fan will not run constantly. It requires that, for continual operation.

Also, you may have the humidity extraction level set to high. Lower it to 35%. Also, remove and check the air intake filter, as it may need cleaning.

Dehumidifiers that are not Low Temp models have a difficult time operating in basement applications. Because the air temp at floor level is colder than at shoulder level. At temperatures between 40 & 60 degree F, regular dehumidifiers struggle to keep up. Raising it up off the flow on to a sturdy table, counter top, etc that can handle the weight of the unit, plus a full bucket of water can really help.

I hope this was of assistance and thanks for choosing FixYa.

Our de-humidifier is running cool but there is no water in the bucket, should there be?


Is it warm outside,and do you have your A.C. on? Dehumidifiers ,just like A.C. systems, remove humidity. If the weather is cold, put an open gallon of water in front of your unit and let it run a day or so. If the bucket gets water in it, and the container of water goes down, then the unit is working.
