SOURCE: Really thick ice on back of dehumidifier

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

The only thing you need to replace would be the temp control it sounds faulty hope this helps :).I had the same problem with mine and that is what went wrong.
