the problem just might be that your are trying to use this unit at a time of season that is cold weather. there is no humidity in the air so the unit is cycling on and off .there by the noise you hear. dehums work best when the temp is 65 degrees or higher and the humidity level is 60% or higher. and that means outside. in order to have humidity the water has to be heated up to the point that it starts to evaporate.

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.

I have had the same problem. Following the advice of someone on these pages I opened the machine up and checked the fan with a meter. On my model (the 404) it has two settings so two leads; one seemed okay, the other was dead. I checked the circuit where the fan connector plugs in and I got that both speed settings were supplying plenty of juice. Apparently the fan motor is dead. A replacement runs $79 at http://www.appliancefactoryparts.com/. I ordered one; we'll see what happens.

It sounds as if the unit has lost it's refrigerant charge. Take to small appliance repair for confirmation, but it probably leaked out.

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
