It is now frozen because the humidistat, which controls the on/off cycle, is starting to age and forgetting to turn off the dehumidifier. Try removing the humidistat and, using compressed air, blow it out thoroughly of any dust. Then spray the rotary control area, including electrical parts, with WD-40. Then, blow dry again with the compressor and try again.

SOURCE: Ice on dehumidifier

A dehumidifier works by cooling the metal pipes on the back of the unit to create condensation (water vapor in the air). This then drips into the collector bucket. If the unit runs too long the cooling tubes can get too cold and freeze the condesing water vapor. Unplug the dehumidifier and let the ice melt, when u turn it back on, turn it down, it may be up too high. If you find this solution helpful please rate it.

First you would need to clean the filter. LG recommends cleaning the filter every 2 weeks on their dehumidifiers. The second thing you need to do is clean the coils periodically. On this dehumidifier it should include a brush for cleaning the coils. It is located on the top of the bucket. To access the coils the following needs to be done:

1.) Unplug the unit from power
2.) Remove the bucket and also the air filter
3.) Remove the front pannel by removing the 2 lower screws and depressing the tabs.
4.) Once the panel is removed you will see the coils. You need to clean them with the brush. Go in an up and down motion to remove the dirt and dust.

Now use the reverse steps to put it back together. If your dehumidifier runs often I recommend you clean the coils about every 3 to 4 months. This is a common problem on alot of dehumidifiers and people think their dehumidifier is broken. Most of the time the coils are just dirty which causes the water to stay between them and freeze. Keep me posted. Also if you found this response helpful, please rate this solution when you get a chance. Thanks - Tech101

Your unit has a sealed system leak. The sealed system is warrantied for five years. Check your owners manual for this info. You will need your receipt and to call an authorized LG warranty dealer to exchange it.

How do you get the front grill off?


Remove water collection bucket. Remove two screws now visible (previously covered by top edge of bucket). Front panel now has to be flexed a bit on the side to release it from the metal side panels, near the lower portion of the front panel, then panel swings up and un-hooks from top.

I have an LG LHD45EL dehumidifier. The manual shows removing the front grille to clean the coil by placing a hand on each side and pulling toward you. Mine won't budge and I'm afraid to pry the plastic...


I have the exact problem with my LG LHD45EL as lubbock51's Aug 17, 2010 question. (see below) Isn't there anyone out there that's had this same problem and resolved it. I too am afraid to pry the grill for fear of breaking it...it made out of plastic so it won't take much to break the grill if I did.

This will need to be serviced. LG has a 5 year warranty on these models. They usually will tell you of a service center nearby which will service it free of charge since it is under warranty. If you do not live near a service center they may ship you a replacement and you send your old dehumidifier back to them. Make sure you have your reciept when you contact them so they can verify it is under 5 years old.
