No water is produced and the air is 65% humidity

It sounds like it needs servicing and recharging with refrigerant gas. It works by running the moist air over refrigerated elements where the moisture condenses and drips into the tank. Make sure you are on the right setting, most have 'blow air, remove moisture, and A/C'..

with a reading of 66 to 67 % rh this is a bit low for normal rooms humidity , I cant see why you'd want to try to get it down to 55% unless its for a special purpose (drying paint?) , I get this question a lot from folks , what I tell em is if you set your airconditioner in your home down to 30 degrees would your house ever get that cold = "no " the houses ability to heat itself is greater than the a/c units ability to cool it (even if its properly sized) so why would you expect a small appliance like a dehumidifier to be able to do any different ? all you end up doing is over working the appliance and costing you extra money in lost power
the general excepted room humidity is 70% rh this is a industry standard ,that all appliances are designed to achieve , and yes as the room gets dryer it will extract less and less water from air

Hi,

Here is a tip that explains what can be happening to make the dehumidifier showthat the bucket is full when it is not.

It very well maybe, that you have the humidity removal set to high and it's not sensing any humidity to remove. For example, if you have it set on 65 - 70%, that's not how much humidity it's going to remove. It's the level of humidity it's going to maintain in your home. To remove moisture/humidity, the setting should be low, like 45%. As far as the fan running ... many units are designed that way, in an effort to help keep the air circulating and also to defrost the cools.

If you want to test the unit, to see if it's working properly. Place the dehumidifier in the bathroom and set it at 50%. Turn the shower ON and let it run for 20 minutes with the bathroom door closed and without the exhaust fan running. And check on it after 20 minutes. More than likely, there' will be water in the bucket.

Also, there's routine maintenance that should be performed regularly. Clean the air intake filter, clean and wipe off the the compressor coolant coils, and check for clogs in the drain line of the unit.

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

Kreston, check the humidity level you have it set on. It may be that there is not enough humidity in the air for what you have it set on and it automatically shuts OFF.

Keep in mind, whatever level (percentage) you have it set on, is what it will maintain, not remove.
For example - if you have it set on 65%, that's pretty high level of moisture/humidity. But, it's not how much it's going to remove from the household air. Unless, the humidity level rises above 65%. Then it will only remove enough to maintain 65%.

If you want to remove humidity/moisture, you have to lower the setting below 45 to 50%, Try that and I think you'll meet with success.

Hope this helped you. Please let me know. Thanks.

Keep in mind, that a dehumidifier only draws humidity from the air, if the level of humidity is higher than what the controls are set on. For instance, if you have the dehumidifier set on 65 to 70%, that's a high level of humidity to maintain in a house. If you have it set for 35 or 45%, that's a low level of humidity to maintain in a house. Which, generally is what you want to maintain in the hot, humid summer months. I find it uncanny, that all 3 units are not collecting any water. So, it may simply be the case, that the humidity level on each unit is improperly set.

Also, a dirty air intake filter makes the unit strain to keep up and can't take in moisture as it should. So, if you haven't cleaned the filters on a regular basis, not is the time to do so. And while your at it, clean the cooling coils too.

The easiest and best way to test a dehumidifier at home, to see if it's working properly. Is to place it in the bathroom and turn the shower ON and don't operate the bathroom's exhaust fan. Set the humidity level low (45%), turn the unit ON and close the door when you leave. Wait 30 to 40 minutes and check the water collection bucket. If there's water in it, it's working as it should.

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

Hi,
It could be a bad compressor, circuit board, or maybe even a sensor or dehumidistat...
Here is a tip about dehumidifiers that run but do not extract water from the air..

I unscrew the cover were's the air is ****'s inside and I just clean with water pressure.I beleive I have to do this every six month.The problem was;no more water collect,less air came out and the unit was very hot.Only clean the filter is not enough!!

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.

IS THE ROOM HUMIDITY LOW. IF IT IS BELOW 30% THE HUMIDISTAT WILL SHUT DOWN THE UNIT. THE AMMBIENT TEMP SHOULD BE ABOVE 65 DEGREES AND THE HUMIDITY SHOULD BE ABOVE 50 %.
