Dehumidifier runs but extracts no water at all. room is 65degrees & humidity is 75%. no frost on coil & no moisture either. kenmore model no. 580.54501.

Prt of the problem may be a dirty or clogged air intake filter.

Turn the unit OFF and unplug, it before removing the filter to check and clean it.
You can ether vacuum it or if it's really dirty & clogged, wash it in warm water and mild dish washing liquid. Rinse thoroughly, shake off access water and allow it to dry completely, before reinstalling it.
Never operate the unit without the filter in place. As this could damage the unit.

Plug the unit back in and turn it ON. Try lowering the humidity extraction level now, using the arrow down button. For a very damp, humid basement application 35% is a good setting to start with for several days.

Hope this helped you and thanks for choosing FixYa.

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."

There are several reasons this may be happening. The 2 primary reasons are the humidity extraction level is set to high. Lower it to 35% . The lower the setting, the more moisture/humidity is extracted from the air. The higher the setting, the less if any moisture/humidity will be extracted from the air.
On most humidifiers the fan runs almost constantly while in operation. The idea is to continually move the air around and when the unit senses a rise in humidity, above what you have it set on, the compressor will turn ON to extract that humidity.

The 2nd thing that causes the problem is a dirty of clogged intake air filter. Which is easily solved by removing and cleaning the filter. Which should be done at least every 2 weeks, while the dehumidifier is in operation.

I said there were 2 primary reasons. Actually, there is a 3rd. Not enough clear air space all around the dehumidifier. A minimum of 12" should be maintained during operation.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

A couple of things may be happening: The humidity extraction level may be set to high and it can't extract any humidity at that level. Reset/Lower it to 35%. The fans on most dehumidifiers run almost constantly (designed that way) so that it keeps moving the air around. If the sensor picks up a higher humidity level than what it's set to maintain, the compressor will turn ON. This is particularly true, if you operate the unit in continual mode, rather than a timed mode. Also, a dirty or clogged air intake filter, hinders the units ability to remove humidity/moisture.

In addition, operating the unit is ambient air temperature of between 40 & 60 degrees F, causes the unit to struggle to dehumidify the air and the fan to run continuously. Obstructing the air flow around the unit, will also cause it to not function as it should. Maintain a minimum of 12" of free air space around all 4 sides of the unit.

Hope this helps you troubleshoot and solve the problem. Please let me know.

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.

if the room air is cooler than the dehumidifier then they will frost over. normally frosting over means loss of freon but because it is a closed system there probably isn't. if the air's moisture level [humidity] is low then don't even run the machine.

There are three things that must be working to extract water. The 'coil' (a finned metal part that allows air passage) if it's filled with dust and obstructions, no air can move...no water. There is a blower motor that mus move the air. If it is seized up an not blowing air...very little or no water. The compressor uses condensation from the air moving across its coils (like the moisture than forms on a cold glass on a humid day) to extract the water from the air. If it's not working then no water.
So, if there is air blowing out of the dehumidifier the blower is working. If the air is room temp the compressor is not working. If it's real hot air, and the humidifier keeps cycling on and off quickly, the coil is dirty. Those are the 3 things that need to be working.

You need to determine what's "running". Here's why: There are three things that must be working to extract water. The 'coil' (a finned metal part that needs air to flow across its surface) may be filled with dust and obstructions, so no air can move...then no water. There is a blower motor that must move the air. If it is seized up and not blowing air...very little or no water. The compressor creates condensation from air moving across the coil (like the moisture than forms on an ice filled glass on a humid day) to extract the water from the air. If it's not working then no water.
So, if there is air blowing out of the dehumidifier the blower is working. If the air is room temp the compressor is not working. If it's real hot air, and the humidifier keeps cycling on and off quickly, the coil is dirty. Those are the 3 things that need to be working.

Unless equipped with special equipment most dehumidifiers will produce little if any water under 65-70 degrees. Many state operation down to 50-60 degrees but this was under lab conditions and therefore a marketing tool. The best performance is gained when the air temperature is above 70 degrees. The water you are finding is from melting frost, if you have a humidity problem you should be adding heat to the area to be dried, warm air holds much more moisture than cold and drying is much more effective if you can heat the area to around 80 degrees.

Most dehumidifiers have a "Frost Guard" mounted on the condensor coil. If frost accumulates on the condensor coil the frost guard turns the compressor off until the frost melts, then comes back on again. For the dehumidifier to work properly, the surrounding (ambient), temperature must be higher than 65 degress. This temperature allows the moisture in the air to condense on the coils and drip into the reservoir without freezing up on the condensor coil. Also, if the humidity is too low, (below 45%), the same condition will occur. So it will help to keep the parameters in mind when you have this issue.

Thank you for your allowing me to advise you on this issue.
