Ice on dehumidifier

Ice is forming on the dehumidifier, in a small band along the top edge, where the front and top panels join, just above the control panel. The unit has been working fine, the filter is clean.

    We are having the same problem and the unit is not working nearly as efficiently as it used to.

  • Anonymous Jun 25, 2008

    I will try turning the unit down. I have unplugged and let the ice melt but it starts doing the same thing again.

    my dehumidifier wont **** up water

  • festus2 Jul 14, 2008

    Had same problem. Now condenser doesn't even get cold. Compressor gets hot and condenser does not get cold. Maybe lost it charge and only 2 years old.

    the ice forms exactly as descibed by the other owner...only a small portion of the top coil gets very cold....



    this is usually from a lack of refrigerent and this is caused by a defective leaking compressor...

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.

Thanks - Tech101

HI, OUR DEHUMIDIFIER SWEATS ON THE TOP (FORMS WATER BEADS) AND PARTIALLY FORMS ICE.


>check if the steam creating by the dehumidifier is enough or balance to neutralize the fresh air supply of the dehumidifier by not creating a too much moist or more tha 40% relative humidity so that water beads would not form from the top of the dehumidifier unit or from its supply of fresh air.

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.

Ice forming on top front part of unit


usually, ice build up is caused by low refrigerant levels (a dehumidifier is essentially an air conditioner). depending on the unityou may or may not be able to service it. Some of these systems are sealed at the factory and a pierce valve is needed to add refrigerant to the system.

Ice forming on the to


Usually this happens for one of two reasons: 1) there is a problem with the refrigerant and/or compressor (like a little leak of refrigerant)
2) the room that the compressor is in is too cool (below the operating range of the dehumidifier)

If the unit is under warranty, call for service if you know the room is above the minimum operating temp. If it is a problem with the refrigerant, they will probably replace the unit.

I hope this helps.

(we have an LG dehumidifier and had to have it replaced when it was less than a year old - it was icing up in the summer. It still iced up in the winter (at times due to cold in the basement).)

Bucket not filling - ice forming on lid.


You've developed a sealed system problem.

A large block of ice formed over the entire front where the vent is. Basement temp was apprx 64 degrees F, but this model is supposed to operate at lower temps. Discovered after it was running continuously...


35 is way low; why not 50%?

At the cooler temp you may need to also run a small fan or space heater blowing on it.

It is working, but the setting is too low and the temp in the room is too low

Running, but no water coming out. Is forming ice


Your machine has a sealed system leak and is low on freon. Read your owners manual and there should be a 5 year sealed system warranty. If so you will need your purchase receipt and call an authorized LG dealer for an exchange.
