LG dehumidifier developing ice

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

Inspection of the coils is step one...If reasonably clean ...your problem is a bad leaking compressor...this will require replacement...my unit was 2.5 years old when this occured..

LG was very good to me and sent a replacement to my home after I sent the defective unit to their service company in my area...

Yes I'm not happy that the unit failed in 2years but LG was very helpful and did make all good..


If you have to clean the coils every 2 weeks you got tooooo many cats..
