Unit forms ice on back coil. Please advise


The freon in the unit is low. You probably have a leak.

My LHD45ELY7 freezes up. Why? Is it broken?


Assuming this isn't just a weather change, it probably needs cleaning. The unit is supposed to run the fan without the compressor intermittently to give the cold coils a chance to warm up a bit so the little bit of ice that normally forms can melt off. But once they get dirty, this melting and runoff is impeded. Spray some formula 409 (or similar) on the coils and rinse thoroughly. It is also possible that the unit is not switching over to run the fan only (without the compressor). This could be due to a bad temperature sensor, or it may be dirty or corroded so it thiinks the coils are a bit warmer than they really are. If you can find this sensor (it's usually attached to the coils with a little spring clip) see if you can't clean up where it makes metal contact (thermal contact) witht the coil. Good luck.

Ice is forming on the top of the unit, it is running but not very much water is collecting


Ice will often form if the humidity level is high or the air intake filter needs cleaning. If it's because of high humidity or being used in a basement, the unit may appear to still be running, but it's usually just the fan and it's going thru a defrost cycle.

If you check the filter, be sure to turn the Master ON/OFF Switch OFF and unplug the unit. Remove the filter and clean if necessary. If you wash the filter, use warm water and dish washing liquid. Rinse thoroughly and allow to dry completely, before reinstalling it. DO NOT run the dehumidifier without the filter installed.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

Our dehumidifier has formed a sheet of ice amongst the coils and will no longer pull moisture from the air. The hole from which the water drips is completely iced over. It is 70degrees in the room and...


Turn the unit OFF and unplug it from the wall. Allow it to thoroughly thaw and remove the humidifiers cabinet to expose the cooling coils. Clean those thoroughly and coat with a very light coating of WD40. Reassemble the humidifier and turn it ON. Set your humidity control at 50% and allow the unit to run for at least one hour. Check for water collection in the bucket and for any signs of icing, after one hour. If water is in the collection bucket and no signs of icing, lower the humidity to 45% and continue. If you not any signs of icing, watch the unit, as you need to know if it automatically goes into defrost mode. The compressor should shut off, but the fan will continue to run until defrosting is completed. If it doesn't the auto defrost sensor has failed and will need to be replaced.

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 ices up


Hi,

Might it be that the unit simply needs a full thorough cleaning including the tiny spaces between fins? Dust can gather and block air passage on many of the components of a dehumidifier not only on the filter. in some extreme cases, the unit could be undercharged (insufficient) coolant. A service shop engaged in the business of cleaning and repairing air conditioners should also be able to work on your unit.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

We came home to this problem the other day, water all over the basement, leaking out the bottom left side, nothing in the collection basin but plenty would spill out if I tipped the unit forward. After searching the web and these forums I theorized that the coils were frozen. I let the unit thaw. No luck. I removed the faceplate and discovered thick, wet silt had filled the internal collection plate and was clogging the drain. I stuck a pipe-cleaner through the drain and the problem was fixed. Took some paper towels and cleaned the whole thing. Works like new. I assume the unit will need to be cleaned regularly to keep it going. To remove the faceplate, unscrew the two phillips' head screws under the faceplate along the sides, then take a flat head screwdriver and pop the tabs holding the face on, one tabe along each side. There are also two tabs on top, but you don't need to mess with those, as they simply act against gravity. Whole thing just clips back together after cleaning. I have no idea if this voids the warranty.

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.

Thanks - Tech101
