Dehumidifier ices up on back - Why?

I don't know if the machine is actually capturing any water, but ice forms on the back and stays as long as the machine is running. Is it fixable or does it need to be replaced?

    The machine does not collect any water. The ice forms on the outside of machine while it runs and just stays there, it does not drip. What do you mean by insulation and refrigerant - Are these added to the machine inside somewhere?

There are an amazing number of low probability answers along with just plain **** out there. Here is the answer:

The condenser fins are dirty. The dirt stops the water from running off fast enough and so it turns to ice. So, how do you clean the fins?

First of all be careful. Unplug the machine before working on it and DO NOT plug it back in until it is completely dry. By the way, if your dehumidifier has a filter, remove it, wash it well with soap and water, dry it, and then try the machine again. If it still ices you are going to have to disassemble the machine. How you do this depends on the make and model. In the easiest case you can remove the front panel. Usually there are either two screws at the top and two at the bottom, or just two at the bottom and plastic hooks at the top. In the harder situation, you have to take off the whole case – usually this is attached by four screws, two on each side located at the bottom edge of the machine.
You need access so that you can use a hose with a strong spray nozzle to direct water from the inside of the fins toward the outside. You want to do this while minimizing the amount of water that gets on the fan motor. While you are at it, use a rag and soapy water to wipe all dirt from the fan blades – be careful, the blade edges can be sharp.
Working from the back with your soapy water and rag try to get as much soap on the fins as possible. If you work very gently, you can also use a scrub brush but remember that the fins are delicate and you don’t want to bend them. Then, using the hose nozzle from the inside of the machine (you will have to work around the fan blades) rinse the fins thoroughly.

Now, let the machine dry completely. I generally leave it out in the bright sunshine for a full day. The machine MUST be completely dry before you plug it in again. Then reassemble it and you are back in the dehumidification business.

If this is dripping and making a water problem yep it needs some insulation on it as long as everything else is working OK. If it seems short of capacity and or not dehumidifying the problem may be short of refrigerant. You don't mention any of this so I'm thinking its OK and not a problem just how it works in your application.

Hope this helps Please rate me accordingly and good luck.

Dehumidifier


when ice forms on an evaporator unit (coil) there is an indication of internal problems with the unit. IT may occur if there is insufficient air flow ( dirty or fan speed to low ) but when this happens the thermostat just orders more gas through the tx valve and so more ice is formed then the thermostat reads it as too cold and so cuts the gas flow back by controlling the operation of the tx valve
Water from a dehumidifier will depend on the atmosphere humidity so the lower the humidity reading the less water collected
However I suggest that you have a technician check it out as the compressor start/run capacitor may be faulty and that is why the compressor is not getting hot as it may not be running properly

Does not collect water in bucket but runs all the time


Does it have a filter?

"
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."

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.

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

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).)

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.

Dehumidifier freezes up


Most dehumidifiers need warmer air to work properly. The temperature in a basement is usually 60 - 65F; too cool for standard models. You could buy a "basement" dehumidifier. They're designed to work at lower temperatures; some as low as 40 F. Costs are about the same as a standard dehumidifier; you just have to find it.

For a cheap fix, try this; it seems to be working for me.

Since the condensate coil (the one icing up) is cold, the air entering it is too cool and the condensate frosts up the coil. Additional condensate freezes to the frost and before you know it, you've got a block of ice. Since the air coming out of the front is very warm take a large piece of cardboard around 6' x 3') and form a V. Placed it in front of the dehumidifier so it channels some of the warm air back to the rear where it warms the moist air up before it hits the cooling fins. It's helped keep the ice down.

If you want something attractive, any screen that redirects some of the air back to the rear will work. Just leave the top open so it doesn't get too hot and the some of the drier air gets out into the room.

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.
