Question about Kenmore Dehumidifiers

Open Question

Kenmore dehumidifier 580.54501400 doesnt work. Powers up, all the lights come on, however, no noise from the compressor or the fan... My daughter has Leukemia, and can become very sick if we get any kind of mold. I am very handy, but I just want to know if I am better off getting a new one.

SOURCE: Dehumidifier Does Not Collect Water

Hi,
A dehumidifier is just a refrigerating machine with it's shirt hanging out and there is not much in the way of serviceable parts inside.
If the compressor runs - the throbbing sound - and it doesn't collect water then either the intake filter screen is totally clogged with fluff or the compressor has leaked it's gas away, in which case it might run continuously and get hot to no good effect.

If it doesn't run then it may be that the motor capacitor has failed, but that can soon lead to the compressor motor cooking itself; leaving you with an expensive doorstop.

The one thing you might get checked is the "bucket full" switch. There will be a floating part on the bucket which rises up when the bucket fills and eventually makes contact with another part which is connected to a small switch. If that switch has failed you might be lucky and get an inexpensive repair job done.

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

It sounds like you have power to the unit but a component is failing to start the system get an AC tech to check it.

SOURCE: Kenmore 54701 (70 pt) dehumidifier is not prerforming properly

could be a bad humidistat or a bad PTC relay on the compressor, check for voltage going to compressor, and check neutral continuity, if there is both then you have a bad compressor, check warranty on comp replacement, if no voltage then the humidistat is probably bad

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 H. Bay model HB40F dehumidifier. It does not seem to ever actually start the compressor. There is a plastic box on the side of the compressor that contains a couple of coily looking things. It...


It is probably the start device(the coil looking things), as long as you don't hear the compressor humming. A loud hum is a lock compressor and the cost would be far greater than a new unit.

A one year old Kenmore dehumidifier model #580-54501700 runs but no water comes out. Do not hear compressor run. Unit powers up and fan runs.


these units are notorious for losing their refrigerant charge,if the compressor isn't running that is one reason why, have a gauge put on the system to see sealed system pressures otherwise the low-pressure switch could be bad,you can test this with a continuity meter

Kenmore dehumidifier M/N 580.53650200 only runs for about 1 minute, then stops. Dehumidifying level is set to minimum (40) and it's damp in the basement so I know the air is not too dry. The fan works, the...


Well to knowledge the problem 40 percent is dry. means your basement is great. humidity should be 30/50 percent 50 grows mold. also if it runs for a min the auot shut off is activating. check this first.

Dehumidifier not dehumidifying ...


Save the old one for parts if you get the same new one but I def. don't reccomend buying this unit again. The reviews are bad. The fan is not covered under the warranty except first year or extented warranty. I spoke with Kenmore & Sears about this to see if coverd under 5 yr. Only compressor,tubing & refrigeration system(see inside of front cover for warranty info.)

Sound more like a sensor/circuit board problem to me since fan is turning. I think the signal determins which setting fan needs via sensor assembly to run. I could be wrong. Justa thought.

Can you def. hear the compressor come on. You can look through grill to see fan spin & the compressor makes a clank/clunking noise/ The fan & compressor should turn same time. Good luck! If you got any info. on my fan problem & you have update or fixed your problem I ccould use some help. Check post for my problem.. Thanks! panfan1

Check to make sure the fan works. I have one with a broken internal fan and it will appear to work but will not collect water. Do not be fooled by the noise from the compressor. If your fan is broken, the compressor will run until it overheats. There should be airflow that you can feel behind the unit which should be cool and not hot.
