If your compressor is running but the coils are not getting cold, then you have a problem in your refrigerant circuit.....Most likely a restriction or a leak with a leak being the more likely of the two.

Frigidaire dehumidifier stopped draining from hose


If you have a dehumidifier that is not producing any water then you are wondering what you need to do to get this thing to work for you. In some cases you may be able to do something and in other situations there may be nothing that you can do.

If you do not hear the
compressor running and the unit says that the humidity in the room is higher then the setting, then you have a problem with your dehumidifier.

A few things that can cause this are:

The
circuit board relay has gone bad...replacement of this board will often cost more then a new unit. This also is a very common problem with many dehumidification units.

The
compressor has failed...if you hear a buzz for a few seconds, every few minutes, then you have a bad compressor or at least bad start components on the compressor. Either way it again is a costly repair.

If the
compressor is running and the coils are not getting cold then you have a refrigeration system leak. Recharging or fixing these units is very difficult and is another costly venture compared to the price of a new dehumidifier.

If the
compressor is running but the fan is not, this also will cause low water production and continual freezing of the coil.

If the
compressor and the fan are running but the coil is totally blocked then you will get no water production. Air needs to be continually moved over the cold coil to get the water out of the air.

If nothing is running, then you may also have a
control board failure. Or the humidity sensor or humidistat has gone bad which tells the machine to run. If the sensor says that the humidity is low enough then it will never run.

Also if nothing is running check the
float switch or the bucket switch. Many of these switches are very touchy and if you do not have the bucket in place just exactly right it will not trip the switch to allow the unit to run. These switches often are more fragile then they should be and break easily. The good thing is that when available they are easy to replace and relatively inexpensive.

There are some parts available for a few brands, but with the prices for most of the parts that you can replace running anywhere from 40.00 - 80.00 dollars, replacement parts with labor to install them, makes a repair more then the few hundred dollar cost of many of these dehumidifiers.

As you can see there are quite a few things that can cause your dehumidifier not to work. Systematically go through the list and eliminate things to get to the bottom of the issue causing your problem and then decide if it is worth spending the money to try to fix the old unit. Only you can make that decision.

Compressor running very hot but almost no cooling. Fan running


make sure the coils are clean both evaporator and condenser,then if there is a capacitor in the motor circuitry,check this,finally if the coils frost,then clear up and frost and clear up time and again,this is a sign of low refrigerant R134a,and this also will make the compressor run hot

Unit runs but no water collects in bucket. Unit is over a year old and has run continuously that whole time. Up till now it has performed beautifully. Is it just worn out?


Hi;
Your dehumidifier is similar to a refridgerator or air conditioner. It has a compressor and coils, and a fan. Basically, the unit has to **** in air with it's fan, and as the humid air goes across the cold coils, the humidity condenses in to water. If the coils are not getting cold, they won't condense any water, or if the fan isn't running, or the coils are dirty. If you check your unit over, see if you can tell if anything isn't working. Make sure the control knob is set at the highest setting. If the compressor lost it;s refridgerant charge, and won't get cold, it isn't probably worth fixing

Amana 30 (looks like dk25) unit runs but coils freeze up


Most dehumidifiers have a defrost mode in which the compressor is turned off to give time for the frozen water to melt. The freezing problem ocurrs when the unit is used in very cold weather. Check your manual to see if this unit comes with automatic defrost mode. If it does, it would appear that it is not operating correctly and you can request warranty service. If no defrost mode is available, then your only option is to heat up the room in order to use the dehumidifer within its limit of operation. Some units can operate as low as 36 F, but most units cannot go that low. Find out what your unit's specs are from the manufacturers web site.

Unit runs but no water in storage tank


Make sure conditions are not too cold or too dry already.
Is the compressor running?
Set the unit to the continuous run setting or the dryest setting
compressor should start.
If compressor runs but the evaporator doesn't get cold the freon has
leaked out.
If compressor doesn't run no matter what you do the board may be bad.
Also the fan must blow air.

Running but not collecting water...


Dehumidifiers have only a few components, and operate on the same principle as a refrigerator, freezer, or air-conditioner.
Components Residential dehumidifiers have a cooling system made up of these primary components:

  • The compressor is the quiet motor (engine) of the cooling system. It's the black, football-size component at the bottom of your dehumidifier. The compressor runs as long as the dehumidifier humidistat (the humidity-sensor) calls for a reduction in the humidity.

  • The condenser is a series of finned tubes, similar to a radiator. It's usually near the circulating fan.

  • The evaporator is located near the back of the dehumidifier, right above the water-collection container. It also resembles a radiator or a coiled-up set of tubes. When the dehumidifier's humidistat senses increased humidity, it cycles on, which starts the compressor and circulating fan.

  • The circulating fan circulates the air over the evaporator and condenser coils.

Principle When the unit runs, the circulating fan and compressor also run. The fan continually draws room air over the evaporator coils, which are cold, and then over the condenser coils, which are warm. Because the evaporator coils are cold, the moisture in the room collects on them--just as the outside of a glass of icy liquid "sweats" on a warm, humid day. When the moisture on the coils increases, it drips off of the coils into the collection container.

The air then flows over the warm condenser coils and out into the room. This process removes water from the air and, because of the heat from the fan motor and compressor motor, the exiting air is somewhat warmer, as well as dryer.

Unit Runs (fan and condenser) but no water?


By condenser I assume you mean the compressor is running. Is there ice forming on the front coil?

No water in tank


have you turned them off, waited a long time, and restarted? if yes, but still problem, both have developed freon leaks. the coils may have "frozen over", verified by looking at them-do they appear frosty? caused by humidistats that are not functioning properly (starting to corrode)...try turning down the stats to allow motors to rest (and frost to melt)
