Problem for Eva-Dry EDV300 Dehumidifier
Why does my dehumidifier ice up?
Same Problem

- Samsung dehumidifier. Worked great for a year and a half now ices up on left side of outside cabinet and no water is being collected. I run this puppy 24/7 and up until a week ago it was great.- odjmoJul 07, 2008
- I am experiencing the same problems with my 45 pint Fedders dehumidifier. I purchased it about a year and a half ago and it worked perfectly and all of a sudden it is icing up and not producing water. My basement is about 1000 sq. ft. and the temperature is around 70 degrees.- sonnypartinJun 19, 2008
- ices up in 5 min is all clean any ideas- GuestMay 24, 2008
- Same exact issues as everyone else. My unit worked well for 3 years and 2 years in this exact location. All the sudden it is icing up constantly and not generating any water. Will run continuously. I think the solution is the to throw it in the trash. I pulled it apart - clean as whistle and no obvious issues. Good airflow, temperature in the basement is steady at around 65 - not cold enough to cause the issue. It ices up in about 5 minutes. I am uncertain of what controls the switching from cooling to thawing (switching on and off the air conditioning unit) but it is either the electronic sensor/switch that runs that cycle or a mechanical part that actually stops the flow of the refrigerant. Just thinking out loud - no real clue what to do. One thing is for sure, I will not buy Fedder again.- Richars2May 20, 2008

My Maytag dehumidifier, Model M7DH45B2A*A, worked fine for a few years but then last year it started icing up. I thought it was dirty so I took it appart to clean it and I found a sensor with a clip hanging loose by the cooling coils. The clip was all black and corroded but looked like it was supposed to clip the sensor to the cooling coil. The wire from the sensor appears to go to the "Pause 1 hour" control so I'm guessing the sensor is supposed to sense when the cooling coils are freezing up. I think it probably signals the unit to shut off (Pause for 1 hour) to allow the ice to melt and then allow the unit to come back on. The solution then appears to be to refasten the sensor to the cooling coils somehow. Any suggestions?

Condensor fan may have stopped running. This will cause ALL refrigeration systems (dehumidifiers are nothing more than small refrigerators) to ice the condensor coils. Low freon is also a possibility, but, imho, very unlikely. If possible, remove the cover and look at the fan-it's usually behind the coil--if it isn't running when the machine is on (big black cylinder, the compressor, will hum) you found your problem. Fan for mine is $40, I can install myself. If you need a repairman to do it, toss the unit and buy new.

For those of you with a low refrigerant problem on an appliance without a service port, hardware stores sell a tap-in type valve wich allows units to be serviced quite easily. Use caution when doing this type of service work. Stay Alive Folks!!!

Because the room is too cool. Because dehumidifiers remove moisture from the air by chilling a set of coils and allowing the moisture in the air to condense on them. If the room temperature is too cold, the moisture can freeze. To prevent ice-up, you may need to either raise the dehumidifier to a higher (warmer) location or increase the temperature of the room.

I believe the actual problem is that the unit is low on refrigerant. it is not cycling around properly, hence why it only gets cold in one area if you watch the lines, they freeze up from the beginning and inch there way to a point and then stop. the refrigerant is not moving I think, I am not an expert but this is my problem and I have heard from pros that this can be a symptom. any bumbling idiot will tell you its your temperature because they want to sound smart, but its not the case. Another symptom I am having is no hot air is coming out. I dont think there is a service port on these either so it would have to be professionally installed

my lg ices up also. It`s not a room temp. issue in my case it worked fine in the same location for a year and a half. I also made sure the coils and filter are clean.

I am having the same issue, all of a sudden the coils are all icing up, the unit is cleaned, and adiquate ventilation. what can I do for this?
Comment by Dave 58, posted on Nov 20, 2007
The temperature in the room is ~72°F. The unit should not be icing. There is something else wrong and I can not tell what it is. I have cleaned the unit and ensured proper air flow. This still did not improve the operation. The unit ices up immediately no matter what I do. The thermocouple located on the coil is rusted. I cleaned this. The bracket should have been made of stainless steel. I can not tell if the temperature sensor is working or not. If I had to guess, I would assume the thermocouple is bad and needs replacing along with the bracket. The unit I have is Fedders A7DH45B2A.
