LG LHD459EL Dehumidifier - Answered Questions & Fixed issues

Sounds like its compressor is pulling too many amps trying to start, thereby blowing the fuse. That would indicate that the compressor is most likely locked up. If so, it's time to replace that dehumidifier. Repair by a shop is far too costly, and you're better off using those bucks to buy a new unit.

My unit runs but will not collect any water in container or when I use the hose.

We had a similar situation and the problem was solved when we removed and cleaned the filter which is accessible once the bucket is removed in the front (pull it down and out). Ours was very dirty and it sits between the humidity control dial and what we believe to be a sensor. Once cleaned, the compressor engaged immediately.

A little condensation is not something to worry about. But, a lot can be caused by a dirty or clogged air intake filter. Which can also cause the cooling coils to freeze.

Turn the unit OFF & unplug it, before removing the filter for cleaning.

Also, maintain 12" to 18' of clear air space all around the unit.

If the unit is in an extremely moist or damp environment, 55% is not really a low setting. 35% would be more appropriate for this type of environment.

Check water pan to see if empty. Also check for loose or burnt wiring. Also check for internal resets or safeties

Hi,Here is a tip that explains what can be happening to make the dehumidifier showthat the bucket is full when it is not.Dehumidifier Problem It shows Bucket Fullheatman101

Error Code '1' indicates that the air intake filter needs to be removed and thoroughly cleaned. be sure to turn the unit OFF and unplug it, before removing the filter. Never operate the unit without the filter in place. Doing so, could cause damage to the unit.

Hi,

Here is a tip that explains what can be happening to make the dehumidifier showthat the bucket is full when it is not.

Dehumidifier Problem It shows Bucket Full

Hi, Compressor is bad... tripping the breaker...

There are many reasons why a dehumidifier willnot work or collect water.
Here is a tip that I wrote to help people to figure out what is going wrongwith their dehumidifier

Dehumidifier is running but no water is in bucket

No, not really. As the unit has to be in a level position to operate properly and not overflow.
If the unit is sitting on carpet, this will often times cause the vibration noise. I don't know why, but it does and it does with my 4 year old LG unit. I have noticed, that once the tank reaches the 1/2 full point, it will vibrate sometimes. I solved the problem by firmly smacking the left & right sides of cabinet at the same time, with my open hands. The vibration stops immediately and continues to run until it shuts off because, the humidity extraction level has been reached or the tank is Full & needs to be emptied.

It's a simple solution, but it works. I hope it works for you and thanks for choosing FixYa.

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.

Rick. the freezing of the coils can be caused by several things:

1. Air intake filter needs to removed and cleaned.
2. The coils may be dirty. Clean the coils with warm water, wiped dry and a light coating
of WD40 applied to the coils.
3. Restricted air flow. Maintain a minimum of 12 to 18" around the entire dehumidifier while
in operation.
4. The air temperature at floor level is 40 degrees F or lower, than the ambient air temperature
at shoulder level. This is particular true in basement applications. Raising the unit up off the floor
on to a sturdy table, cabinet top, etc, that's strong enough to hold the unit, plus a full bucket of
water generally resolves the situation.

Worse case scenario is that the defrost sensor has failed or there is a small leak in the cooling coils.

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

Anbna, there is no reset button for your discontinued model. However, you can try resetting it by doing the following:

Turn the ON/OFF Switch to OFF and unplug the unit for 15 minutes.
Once the time has elapsed, plug the unit in and turn the unit ON.

Hopefully, during that 15 minute timeout, the electronics reset and reverted back to the original factory settings. And the unit will turn ON when you press the ON/OFF Switch.

It's also a good idea to check the outlet it's plugged into. It very well could be an issue with the outlet (no power) or the circuit breaker for that outlet has tripped.

If you continue to have a problem getting it started, contact LG Customer Support 1-800-243-0000.

I hope this helped you to further troubleshoot and solve the problem.

It may not be setting on a level floor or the hardwood flooring or tile flooring is allowing it to vibrate more than it normally should. Also, remove the air intake filter to make sure it's clean.

Hope this helped you, Kathy. Please let me know. Thanks.

First off, Ted. Freon is no longer approved by the EPA. R134a is the approved refrigerant gas for all compressors. However, you may be overlooking the basics of what can cause the problem you've been having. There are 5 of them and don't require any serious repairs. 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
in basement applications level. 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.

I hope this helps you to troubleshoot the basics and solve the problem.

The following link is to the Owner's Manual for your unit. Once the link opens, look to the right of the page and you will see Dehumidifiers Manual English. Click on that and the manual will download. Yours is a unique setup, so it's best you see not only the instructions, but also the pictures. Look at the section entitled Disposing of Collected Water, Page 12.

There are 5 basic, yet solvable reason 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 manually
Controlled model, set the knob on 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

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.

Mike, the LT in the model number, usually indicates that it's a low temperature model. If you root cellar has an unpaved or unfinished floor, I would highly recommend that you raise the dehumidifier at least up a foot or two, off the floor. As the ground temperature is colder than the air temperature at shoulder level. Plus, it will help keep insects and critters out of it. Use something sturdy, that can handle the weight of the unit, plus a full bucket of water. Even if you are going to use the hose drain feature, rather than the bucket, I would still get it up off the floor.
