Hi,
It might be worth checking the intake screen to make sure it isn't clogged with fluff. Also, the on / off switching is often linked in with an ice-detector and a humidity sensor and if either of these have come loose from where they should be problems may arise.
One rather unlikely possibility, from your description of the fault, is that the microswitch for the "bucket full" detector is defective.

I have one machine with a defective humidity sensor and it will only run when I select "continuous" running as opposed to "60% humidity".

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

Your unit is probably operating in defrost mode. When you use a dehumidifier in a cold room, the condensing coils can freeze water. The unit senses this and thus stops the compressor until the water frozen on the coils melts. Then it resumes its cycle. This is a problem you will have during the winter months. It makes the operation of the unit inefficient, but this is otherwise normal behavior.

Why does compressor continue running, even with dehumidifier turned off?


Hello Bernard, thank you for your post!
I see that you are experiencing an issue with the Frigidaire dehumidifier, FAD704DWD, compressor consistently being on. This could be a possible issue with your control panel or sensor. Since it could be any one of these underlying issues I would suggest contacting the manufacturer for further assistance. Hopefully this information is helpful to you. -Matt

2 yr. old. worked great. Then started shuting down self changing setting to low. shortly after, shuts down after 3 min. no water collection, unit is hot. Took apart. Cleaned everything inside, and filter....


Robinson, it really sounds like the compressor is overheating. This may be caused by a low refrigerant gas in the compressor. Or the compressor's oil has leaked down. But, if you took the unit apart to clean it, I would think that you would have noticed an oily residue. If it is the compressor (other than needing to be recharged) it would cost almost as much to replace it, as it would be to buy a new unit.
At least with a new one, you'd have a one year warranty and more, if you purchase an extended warranty.

Hope this helped you.

My kenmore model # 580.5450.1801 runs, but does not produce water. It is a humid basement, and another unit is working.


Turn the unit on and verify the compressor is running. If it is let it run for 3-5 min then unplug and plug it back in. If the compressor comes back on immediately there is a leak and the system needs serviced. If the compressor is not running further investigation to narrow down the cause is necessary. If the dehum is out of warranty replacement is the better option when sealed system repairs are needed.

The Kenmore 106.955501 dehumidifier works well when first started, coils get cold quickly, fan runs, air moves well. after 1 hr when the compressor needs to kick back on, the lights on that circuit dim and...


Hi,
The compressor will not start when it is hot or it is no longer bleeding the pressure off fast enough on the high side of the refrigeration system and it cannot start under the load. The start relay and capacitor could also be bad...that would give the same symptoms...

Humidifier compressor does not stay on more than 1-2 minutes


Sounds like bad relay on compressor or bad compressor. There is only so far you can go yourself without knowledge in electrical and AC units. Suggest you call a service tech or if you can take it to service cemter near you. Russ

Everything seems to run fine, just hasn't pulled a drop of water


remove the back airfilter, and touch the tubes while the unit is running, if nice and cold, all is well, there just isnt any moisture there. but if compressor is running and tubes are warm , means freon/coolant has leaked out

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.
