Runs but no longer collects water

Not sure. Might have a blown fuse or bad capacitor. Here are some DIY steps:

is it getting cool??if not it needs a thermostat or freon if the compressor still runs

Yes, if the compressor needs to be recharged, a service technician can do it.

In the meantime, try lowering the humidity extraction level to 35%. You may have the extraction level set to high.

Hope this helped you. Thanks for choosing FixYa.

There are 5 basic, yet solvable reason for what you described. Please pay particular attention to numbers 1 & 2.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%. If you have a manually
controlled model, set the humidity extraction level on Maximum.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this helps you to troubleshoot and solve the problem.

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.

I just had one giving me the somewhat the same problem. Upon taking it apart I found that the entire inside was filthy. This thing runs in a work area in my basement and sucks up all of the dirty air. When you take the water out of the dirty air you have nothing but the dirt and the water. When you mix those together you get mud which is what clogged everything up in mine.

Dehumidifiers need to be clean on the inside to run properly especially all of the fins on the condensor. You will probably have to take it apart and clean it. Concentrate on the fins and the water collection areas. Dehumidifiers remove heat from the air which causes the humidity to collect on the condensor. As it collects it turns into water droplets. Gravity pulls the water droplets into the water collection areas and that flows to your tank. There is some sort of float in your tank that lets the dehumidifier know it is full and shuts it off with some sort of switch. It does this so it does not just keep running and eventually pour water onto your floor. It sounds like your switch and/or float is stuck. Find the float and switch and manually work them to make certain they are working freely, clean if necessary.

If the dehumidifier does not remove water like it should it is probably not getting good airflow. There are ice sensors on the evaporator that tells the compressor to stop working. However the fan will still run to pull warm air across the ice so that it melts, goes into the water collection area and into your tank. Some of these ice sensors work by measuring air flow. If there is no air flow or very limited air flow the sensor will tell the compressor not to work. The fan will run again to melt the ice so that it melts and is removed. If your condensor is dirty and does not allow the air to flow, this could cause your problem.

if it seems to be running normally except no cooling , is the fan in the house running????...Is the house Cold and damp???.If there is no cooling and you know that the compressor and everything else appears to be normal then you likely have a Refrigerant leak and that will cause no cooling.....Usually a very expensive repair...if your unit is 5-10+ yrs old you likely need a new "A" coil.

compressor run but gas charge not enought
so it not very cool,and no water come out

Try setting you temperature or fan speed lower this may help.
In order for the unit to remove moisture the coil has to be below the dewpoint.

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.
