I have a 50 series w/ digital humidity level readout. Recently unit reads the room at 30% humidity so it shuts off unless preferred setting is set to continuous. Can the sensors go bad that measure the room humidity level? I have had the unit going on 3 years now and never has our basement maintained 30%, normally keep setting at either 40-45%.

If the humidity level is at or lower than 30%, the unit won't turn ON, until the reaches 35 - 40%. It's rare for the sensors to go bad. Just keep in mind, the dehumidifier is reading the humidity near the floor, not up at say, chest level. Humidity levels change every season, so this really would not be that unusual. Make sure that your clean the air intake filter regularly. Cleaning and wiping down the coolant coils would be a good idea, too..

Hope this helped you. Please let me know.

I have a GQF 1502 incubator with digital control and the humidity number stays at 97 but when I put a hygrometer inside the unit it read 47, so what could be wrong.
There could be several reasons why the humidity reading on the digital control is not accurate. Here are a few things you can try:
  1. Calibrate the hygrometer: The first thing to do is to make sure that the hygrometer you are using to measure the humidity is calibrated correctly. You can check this by placing the hygrometer in a sealed container along with a wet sponge or cloth for a few hours. The hygrometer should read close to 100% humidity. If it doesn't, then it may need to be calibrated.
  2. Check the humidity sensor: The humidity sensor in the incubator may be faulty or dirty. You can clean the sensor with a soft cloth or replace it if it is damaged.
  3. Check the water level: Make sure that the water level in the incubator is sufficient. If the water level is low, the humidity will be low as well.
  4. Check the ventilation: The ventilation in the incubator should be set to allow for proper air exchange. If the ventilation is not set correctly, it can affect the humidity level.
  5. Check the room conditions: The room conditions, including temperature and humidity, can affect the humidity level in the incubator. If the room is too dry, it can affect the humidity level in the incubator. You may need to adjust the dehumidifier or add a humidifier to the room to maintain the proper humidity level.

I have a brand new dehumidifier (properly sized) that is running 24 hours/day and producing some water (roughly 1L).
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

See if this helps. It worked for me, but yours may be different. You can only change humidity levels when it's not in Cont. mode.

I cant change humidity levels
Hi Ra Ma,
After you have set the desired humidity, the readout will display the actual room humidity. It has a built in hygrometer which will be on the display while it is running.
You change it and it shows the actual levels.

See page 5 on manual.

Cannot set humidity level to anything other than 50.
Is it reading the room humidity, rather than showing the set point? Check the manual.

It will not run.It cuts on then cuts off. There is plenty of moisture in the air, so it's not the lack of humidity. Any help would be appreciated
Yes, you're right. There's probably enough humidity. But, the level that you have the dehumidifier set on is to high. Please understand, the percentage on the LCD screen is what the humidifier is the humidity that it will maintain, not what it will remove. If it's set on say, 65% or higher, it's not going to remove anything. That's why it turns ON and then OFF. It needs to be set lower than 50%. Probably more like 45%, then when it turns ON, it will continue to run until the humidity level reaches 45% or the unit shuts OFF, because the bucket is full.

I had a previous questioner recently, who after reading what I just told you, said, "Now, I've got it. It works opposite of a refrigerator?" Which is a perfect analogy.

Let me know if it works for you. Thanks.

My new Danby dehumidifier never shuts off
This unit is designed with the intention of the fan running all the time. The compressor cycles on and off with demand, however the fan runs continuously to provide constant room circulation.

yes cycles should be longer either that or the unit is keeping close to desired humidity. Also the unit is under sized 30 pint is for 400sqft. or 20 by 20 room. humidity should be 30/50 percent check your level desired room temp is 70 degrees but its a basemnt 60 works.

User Manual has no guidelines.
When you first turn on the unit it is set to 40% humidity which is the lowest the unit will accept. You can only move the up arrow from that point. The 63 you are seeing is the actual humidity. If you want 50% youo need to press up arrow till 50 is displayed. The manual for this unit is terrible. Just leave it as it is and it will attempt to bring it down to 40%. 30 to 50 is the recommended humidity range.
