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."

My Goldstar dehumidifier model DH304 runs,but fails to pick up any water


If the room air is less than the set air, then there is no water in the bucket, because there is almost no humidity in the air. If it is winter, there is likely not enough humidity in the air to have water collect in the bucket. A dehumidifier will only pick up humidity out of warm air. If you are running a dehumidifier in your basement in the winter, the room may be damp, but too cold for the dehumidifier to pull out the humidity. Try running the unit in the bathroom after having a hot shower without the bathroom fan on. If working correctly the unit should draw water.

Other things that can cause problems: 1.Check to see if the air filter is dirty and/or blocked. 2. The room temperature might be too low, (below 60 degrees Fahrenheit ) 3. Check to make sure that there is no obstruction to the unit that might be causing poor airflow circulation.

Hope this helps you to troubleshoot & solve the problem.

I have a dehumidifier (Emerson I believe - sorry don't have the model # right now) in a very cool basement (55-60 degeres). When I turn it on the coil quickly frosts up as expected and a while later the...


Dehumdifiers work by cooling a coil below the dew point temperature of the ambient air. When this happens frost or water will form on the coil. Most room dehumidifiers work with the room temperature above 65 deg F. It works well when the temperature of the room is 65 deg F or higher. But when the temp is below 65, it won't work because the coil does not reach the dew point.

There are cold temperature dehumidifiers that are designed to work in colder environments such as basements. They can work in a environment as cold as 40 deg F. Check your owners manual to see what type of humidifier you have to see what is the minimum operating temperature for you unit. Hope this helps you.

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.

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.

When do you use the dehumidifier?


In areas with poor circulation and humidity over 80%.
If the room temperature is close to 60, the coils may be frozen (completely encased in ice). If this is the case, move it where the water can drain off - about 1 gallon which may NOT run into the drain bucket.
I out mine over the floor drain.
Turn off and it will defrost over night.
Only specially made dehumidifiers work below a room temp of 60 degrees (the temp of a basement in winter).
Does it need to be running? A digital humidity sensor from Radio Shack is cheap and may tell you the humidity is OK - only 50% or less.

Kenmore 54501 turns on but nothing happens in my damp basement


A dehumidifier heats and cools the air to remove moisture. Most are like a small air cond. The Condenser coil is right in front of the evap.coil. So the compressor may not be coming on. Does it sound the same as before? It may be low on freon. You will have to get in there and listen and feel the lines at or near the compressor, Learn how to get down in there to the compressor. Run it for 10 Mins. unplug it, open it up, and feel the lines. Some lines should be or can be HOT to the touch. Some should be cool. The smaller the line the hotter it should be, and the compressor should be warm (to hot) to the touch. repost for more info.

My Fedder's dehumidifier can run for days and there will be NO water in the bucket.


I was told that it may be too cold in my basement (55 degrees currently) and my coils may be freezing up and that's why it's not collecting any water. I will wait a month or so and then try running it again when the temperature outside warms up.

Dehumidifiers and how they work
Heat pump dehumidifiers

Dehumidifiers use a heat pump (similar to an air conditioner's heat pump) or chemical adsorbents to remove moisture from the air without cooling the air.

A heat pump dehumidifier uses a fan to draw indoor air over a heat exchange coil. The coil is almost freezing. The water in the air condenses on the coil and is drained. A second heat exchange coil reheats the air, which the dehumidifier exhausts into the room.

A heat pump dehumidifier dumps heat lost from the compressor and fan motors into the air. It returns to the indoor air the heat generated by the dehumidifier turning water vapour to liquid. I got this off the internet
