LD451EGL no water extraction


Apparently, the fans are running, but the compressor has shut down. It could be a failed compressor, or the charge in the system could have leaked out causing the compressor to shut down.

The 54701 Kenmore Dehumidifier runs and sounds normal, fan running, compressor on. However , it doesnt collect any water whether a hose is connected or just the bucket. No icing up or any weird noise...


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.

I have a DH305 it turns on but does not draw any water out of the air. I took the back off and noticed that the fan is not moving. should it be?


The fan, generally only operates when the compressor is running and then for a short period there after. A lot of this depends on which humidity extraction level the humidifier is set on. If it's set high (50%+), it's not going to do much extraction at all. However, if it's set on 32-35%, it's really going to run and extract humidity/moisture. In the case of your unit, which has a mechanical control, rather than electronic control , The control knob should be set on Maximum.

In addition, if you haven't checked and or cleaned the air intake filter recently, please do so. A dirty or clogged air filter will affect the operation of the dehumidifier. Also, place of the unit is very improtant. You must maintain a minimum of 12" clear air space around the entire unit. And be sure to keep it away from heat generating appliances.

In you want to do an in home test to see if it's work properly. Do the following:

1. Place the unit in the bathroom, plug it in, turn it ON and set the humidity extraction level at Maximum.

2. Turn the shower on hot enough to generate steam. Close the window(s) in the bathroom and Do Not turn on the exhaust fan As you exit the bathroom close the door.

3. Wait 15 - 20 minutes before returning to the bathroom and opening the door. Turn the shower OFF and allow the dehumidifier to run an additional 10 minutes. Then check the bucket for any signs of water. If you find some, the unit is working as it should. If you don't find any water, the humidity sensor may have failed or the compressor needs to be recharged with refrigerant gas.

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

No water is extracted into bucket. Motor is on - although don't feel any hot air coming out of unit


It may be just the fan motor running and not the compressor. Which, depending on what level you have the humidity extraction set on, may be the problem. If it's set to high, the fan is running to circulate the air. If the humidity sensor picks up a rise in the humidity level (higher than what you have it set on), the compressor will turn ON. Lower the setting to 32 or 35% and if the air intake filter is clean and not clogged, the compressor should turn on shortly thereafter. In addition, be sure to maintain at least 12" of clear air space around the entire unit.

Many times the higher settings are thought to be how much moisture will be extracted. When in fact, the opposite is the case.

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

Does not extract moisture from the air. It runs and cycles on and off. I have changed the filter, turned the device off and reset it. Changed the humidity setting. The device is about 4 years old.


Fred, here is an in home test, that will determine whether your unit is working properly or not.

Please the unit in the bathroom, plug it in, turn it ON and set the humidity level at the LOWEST setting. Turn the shower On hot enough to generate steam. Do Not turn the bathroom's exhaust fan ON and make sure any window(s) is closed. As you exit the bathroom, close the door. Wait 15 to 20 minutes before reentering the bathroom. Then turn the shower OFF and allow the unit to run for 5 more minutes. Then, check the water collection bucket for any signs of water. If you find water in it, it's working as it should. It may simply have been a case that the humidity extraction level was originally set to high.

If you found no signs of water in the bucket, the humidity sensor in the unit may have failed or the compressor is low on refrigerant. Either one is repairable, but the cost of troubleshooting it, finding the part and the time repair it, may exceed the cost of a new unit. As, yours is a 4 years old unit.

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

Ice on coils


The short answer is "yes but maybe not for much longer!"

If the bucket is filling up with water it's probably working OK. Have you selected "continuous" instead of, say 60% ?

If the bucket isn't filling up with water then maybe the intake filter is clogged with fluff, preventing new moist air from getting to the cold coils and being extracted. Or maybe the fan isn't running?

I hope this info will be a useful starting point for you.

If these suggestions do help you solve the problem, please give my reply a rating to help others judge my knowledge.
If they do not, please add a comment with more details so I can try to help you further.
Cheers, D
