LG LHD45EL Dehumidifier Icing Over

I have this dehumidifier in the lower level of my house. A very thin layer of frost develops initially over the entire coil when it is started, starts at the top and proceeds over the whole coil rather quickly. It then seems to disapate. However, after it has been running for 12-24 hours, I can come back and the thing is covered in a thick layer of ice. So thick, that it will actually push the front cover off. The air fitler and coil are both spotless and air flow is fine. The temperature is always over 68-70 degrees. Is there a switch somewhere I need to replace? Something that's not triggering the refrigeration to cycle? thanks for your help.

    Tomsat69,



    What is the temp control, where is it located and where can I find one?

    tomsat69,



    The unit I have is completely electronic at the control panel. There are no manual controls other than the electronic buttons that control fan speed and desired humidity level. I'm still not quite sure what you are referring to. Do you mean the actual circuit board for the control panel that's mounted to the back of the front cover?

    The control is where you turn on the dehumidfier on low and high that is depending on what type of funtions you have is it a manual or electronic control?If manual unplug the unit and remove screws around control panel and there should be a tube coming from the control you need to change .And that is the temp control.you need.Hope this helped:)

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).)

Dehumidifier icecing up


Three possibilities for coils icing up.

1. Low ambient temperature in the area where dehumidifier is located. If so, shut down and de-ice it. Then move the unit to a different - (warmer) - location and start it up.

2. Heating element - (which cycles periodically to liquify frost on the coils and allow water to drain) - is malfunctioning.

3. Low refrigerant level in the unit.
