Ice on dehumidifier coils

Recently noticed ice on the coils. I defrosted it, cleaned the coils, restarted, and the ice returned. Located on the bottom of the coils and also freezes into the drain pan. The dehumidifier is a low temp model located in a 65 degree basement (supposed to work at down to 41 degrees). Fan works fine, although the air coming out is no longer warm.

I think you need to raise the setting of the unit. It's running too long and icing up. If you back it down, the compressor will run less and allow more moisture to be developed.

Dehumidifier does not reduce humidity.


Good Afternoon Miguel,

I understand that your Frigidaire dehumidifier, model# LAD704TDL, is not reducing the humidity, due to the coils constantly freezing up. I also see that it is located in good temperatures and in a good position. I suggest contacting the manufacturer directly. They should be able to point you in the right direction to having your appliance fixed. Hope this is helpful.

-Best Regards-
WP

Moisture collecting at the top front when running, even at mid power, over the control panel, sometimes turns to ice. if I shut it off when it is doing this the problem stops for awhile


Well, sounds like you have a good cold section in the dehumidifier-- that is good!-- But I agree-- we don't want water condensing on the surface-- and we surely don't need it turning to ice!
A couple questions to help us get to the next level of trouble shooting this problem:
1.) How cold is the room you are running the dehumidifier in?
(Obviously-- the warmer a room is, the easier to remove moisture--
the colder the room, the easier to drop the air temperature well below the freezing point-- making ice.)

2.) Have the air filters been cleaned/changed recently?
A dehumidifier needs a steady fast moving supply of air across its whole condenser/evaporator surface, in order to remove the maximum amount of water from the air, and not freeze up. (I would winder if something isn't blocking the flow of air toward the top of the coil?-- so that the coil in that area is going well below freezing temperatures, and thus allowing water (or ICE!) to develop near the top of the coil?-- Can you check air flow for us?

3.) You have suggested a good solution,-- especially if the above problems can not be easily corrected: Turn off the unit every few hours, and allow the warmth of the room, to defrost the coil....
In fact-- just to make sure that the air flow is not being restricted by ice deep within the coil-- let it stay off over night-- or bring the dehumidifier into a much warmer room, to make sure no ice is still blocking air flow deep within the coil..

Let us know what you learn about air flow, and get back with us-- THen maybe we need to take the trouble shooting deeper insicde the device.

I hope this helps-- MB

Esco Oasis 2700L dehumidifier ices up. Is there a filter to be cleaned and if so, how to I get to it?


Hi,

The most common cause of frost and ice buildup on a dehumidifier is because the unit is operating in temperatures that are too cold. Many dehumidifiers are not equipped to run at temperatures below 65 degrees Fahrenheit.
To fix this problem, Position the dehumidifier in an area where there is at least one foot of clearance around the unit in order to allow for proper air circulation during its operation. Close all windows, doors and other outside openings to make sure your unit isn't attempting to remove moisture from areas outside of the immediate room. Determine the temperature of the room by checking a nearby thermostat or by using a hand-held thermometer.

Check the filter for dirt and buildup. Unplug the unit from the electrical source and check the filter by opening the filter compartment. If the filter is dirty, it will restrict airflow through the unit and lead to freezing. Soleus recommends lightly vacuuming the surface of the filter to remove dirt. The filter also can be washed in warm water if it is extremely dirty. Once clean, place the filter back in its compartment. Allow for the ice to melt and then restart your dehumidifier.

Does not collect water in bucket but runs all the time


Does it have a filter?

also:

"
It may be that the humidity level or temperature in the room where your dehumidifier is located is too low.

When the outdoor temperature is below 50 F, the indoor air will be dry even when the air inside is warm, therefore when it's cold outside the dehumidifier may collect little or no water.

Air conditioners will also remove moisture from the room, even if it's hot and humid outside, resulting in little or no moisture collecting in the dehumidifier bucket.

Some dehumidifiers have a deicer which turns off the compressor but keeps the fan running. When the compressor is off, moisture is not removed from the air. The deicer turns off the compressor when the room temperature is cold.

Some dehumidifiers do not have a deicer. If the room temperature is low enough, ice may form on the evaporator coil. The ice prevents the dehumidifier from removing and collecting water. If ice forms on coils, unplug dehumidifier until ice melts and room temperature rises."

The filter (on some models) may be dirty or clogged. If so, clean the filter. For instructions on cleaning the filter.

I hope this help to solve, if this answer solve it, remember to rate it. Good luck.

Coils freezing up, is this normal during operation?


Check fan speed. Also if coil (it's the evaporator) is clean.

Compressor runs continually and cooling coils ice up but it doesn't defrost.


probally has lost some charge on the refrigerant. Low charge will ice the coil. Unless you are operating this at low temperatures. The ones I have seen do not have a defrost on them

Coils Ice Up and nothing is dehumidified


If the coil is clean, then have a tech check for a low charge. This will cause the coil to freeze up. Humidifers are known to lose gas and owners aren't told this so end up buying new one and scraping the old one. Trust me on this. I have seen this many times. I repair high end machinery as my business.

i do believe you have it right. either you are low on freon 22 or the coil sensor and clip has failed so it can not shut off for cold conditions. the sensor can be tie wrapped back on if it is that, the plactic should not fail
