I have a 2 yr old dehumidifier and it runs, it just won't pull out the moisture out of the air.


There are 5 basic, but solvable reasons 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 an analog unit
(No LED screen), set the humidity extraction knob 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 helped you and thanks for choosing FixYa

Our Kenmore 50pt dehumidifer is less than 2 years old, only used for 1 summer, tried to use it last week, it starts/runs but does not withdraw any water, please help. Thanks kindly


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 unit is manual control,
turn the control knob to 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. Filter should be cleaned once every 2 weeks.

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.

No moisture


Is the level of water dropping? If so, the humidifier is working. If you have a cool air humidifier you won't see any steam or anything at all. You will just feel cool air. Watch the water level and see what happens.

Good Luck.

Lack of humidity


Try the following test, ( I will resume this is a flow through humidifier)

Spray water directly oin the filter make sure it is saturated. Some water should leak from the bottom. After 10 min measure the Humidity to see if this helped. If there is a higher level of humidity the pbm is that not enough water is saturating the filter. Check the level of the filter & water feed nozzle.

Option 2 is to connect the water feed tube to a Hot water source.

Hope this helps.

Fan is running but humidity is not changing


Q: My unit has been running for several hours. I hear the fan spinning, but I do not notice the water level in the tank decreasing.
A:
First, check the filter to ensure it is wet. If the pad appears dry, remove it from the Base and gently rinse under cool water. Reposition wet filter in the Base. You may also want to note the current moisture level in your home. If the humidity level is over 60% the unit will not put out much moisture
as your air is already saturated.

UV bulb and filter are user replacement items

see manual from my other post

Comment by Soulvisitor, posted on Jan 20, 2008 You should notice moisture on the widows in the room after unit has run for awile, this unit carries a 3 year warranty. More info coming...

4b54ac1.jpg Comment by Soulvisitor, posted on Jan 20, 2008 If water level in tank is dropping and fan runs then I'd say it is working.

OK?
Comment by Soulvisitor, posted on Jan 20, 2008 Q: I hear the fan turning, but I don’t see any mist. Is my humidifier operating properly?
A:
Dry air is pulled through the system and a fan disperses invisible, moisture balanced air. There is no
“mist” emitted. When operating normally you will feel only cool air coming from the unit. Monitor the
water level in your Tank/ Base. If you notice a decrease in the Water Tank over 24 hours then the unit
is operating normally.

Not working correctly


It could be a problem with the water level sensor. It may have gotten stuck, and is unable to correctly sense the amount of water. I just posted the instructions from the manual here.
