Idylis 0526051 dehumidifier - ice build-up. After 7 months of use this started to make a laboured noise that was audible the floor above. I switched the unit off and noticed what appeared to be a "check filter" light. On removing the intake cover I found that there was about 75% ice cover. The temperature in the basement had not fallen below 65F. Any ideas on problem/solution most welcome!

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 2 years old.

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.

I have a Hampton Bay HB50 with the same problem. I replaced the defrost control switch that connects to the compressor inlet line. The part # is 112900550001 and it was about $50.00

was the filter dirty that will do it let it defrost and put it back on

could have overheated the compressor if the filter was really dirty and blown it
