Dehumidifier will not shut off

LHD30 is plugged in and humidity control is set to off. The fan is on low and I have set the unit up to drain into my sump pump. The unit keeps running and will not shut off at all. The unit does work whan the water bucket is used instead of draining into sump pump.

The auto shut off will work when you have your bucket in, as well when you have met the humidy level which you have chosen. Try changing the setting.

Why does the fan run non stop? the compressor runs and shuts off but the fan just runs on high and low. I have 3 other dehumidifiers that the fan runs only when the compressor runs...why doesnt the...


Depending on the time sequence you have this unit set to run, Fredrich's are designed so that the fan runs almost constantly, to keep the air moving. When it senses a rise in humidity above the level you have it set on, the compressor turns ON and runs until the level of humidity is lowered. This is especially true, if you are operating this unit in continual mode.

Hope this helps you and thanks for choosing FixYa.

Just purchased a Danby dehumidifier (model # DDR6O11R). I was wondering when the dehumidifier reaches the programmed level of humidity (example: 40%). Is the unit suppose to shut off completely? I believe...


Depending on which mode you have the unit set on, will determine if it shots OFF entirely or the fan continues to run. In the Constant or Continual mode, the compressor will turn OFF, once the humidity extraction level has been reached. But, the fan will continue to operate, in an effort to keep the air circulating, so that if the humidity level rises, the compressor will turn ON and start extracting again.

In Timed Mode (usually 2 hour or 4 hour) , when the compressor turns OFF the fan does too.

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

Dehumidifier does not see to be collecting water, fan is running but no water from hose


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.

Unit runs but doesn't collect water and there is a lot of water in the basement. Have had dehumidifier for two weeks and was working well before.


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. Also, it's not uncommon on some dehumidifiers for the fan to almost run constantly. It's designed to keep the air moving, in a effort to detect when the humidity level rises.

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 filter no is the time to check and clean it. And while your at it, clean the cooling coils too. Since it sounds like this unit has been working hard for 2 weeks.

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 15 to 25 minutes and check the water collection bucket. If there's water in it, it's working as it should.

For more information on the proper operation of a dehumidifier, go to the Tips section of Fixya and look up "Taking the confusion out operating a dehumidifier".

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

Of our three 54501 Kenmore dehumidifiers, none produced water after two - three weeks. They run but no humidity is drawn out of the air.

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.

New unit, try using in basement. nothing happen, should humidity settings be high or low? Dose humidity level be high? In the bucket whats the plastic cup about? do something alow water to enter bucket?


If you trying to remove humidity, the setting or percentage of humidity to you want to remove should be set low. it's actually the humidity that will be left in the air. In the Hot Summer months, you want lower humidity, as opposed to the Winter months, when you want higher humidity.

"Plastic cup inside the bucket" - that's got me stumped. But, I suspect, it may be a float valve to turn the unit off, once the bucket reaches the full level. The water enters the bucket through a drain tube or hole from inside the dehumidifier, above the bucket.

By best advice, since this is a new unit, that you recently purchased, is read the Owners Manual/User Guide and become thoroughly familiar with the proper operation of your Dehumidifier, as well as how to properly maintain it. As, they aren't maintenance free.

Santa fe dehumidifier running but not producing any condensate. No ice forming on the coils and filter is clean.


You should check if the compressor is running. Your description makes it appear that the fan may be running and the compressor may not be running.

There are many things that can cause a compressor to cease running:

Open defrost thermostat
Bad run capacitor
Low refrigerant charge (caused by refrigerant leak)
Bad compressor relay
Bad compressor overload
Bad compressor motor

Other things to check:

If the fan switch is set to "on" and the humidity control is set to a high humidity level, the unit may appear to be running, but the compressor will not operate. Check the setting of your humidity control.

If the dehumidifier is operating in a room with a high temperature and a low dew point (very low relative humidity), it may be unable to remove any more moisture from the air.

If you are not comfortable troubleshooting the unit on your own, call the manufacturer service department at 1-800-533-7533, EXT 8459. They are very helpful.

DE 500P - Fan will not shut off


If you have the fan icon selected, it is supposed to run continuously. If you use the mode button (not the fan button) to change to relative humidity (the water drop icon), the fan should only run with the dehumidifier.

DH30 Dehumidifier Compressor Does not Operate


I just picked one up at a tag sale, seller said it worked sometimes. Seems to have the same problem as yours. I took the time to tweak all of the connections and then re-soldered the control board with no luck. I finally disconnected the humidity control and it worked fine. By disconnecting the humidity control the unit defaults to it's highest setting and you have to unplug the unit to turn it off. Conclusion so far is that the humidity control rheostat is bad.
Note: Now while running the fan runs continuously and the compressor cycles on and off every 10 to 15 minutes. This may to be normal since the unit appears to be doing its job and I'm not sure how it is supposed to run since a purchased it broken.
