The compressor will turn on, but the fan itself does not turn on. The dehumidifier turns off after a few minutes and does not produce any water. The fan spins really easy by hand when I had it apart. What could be the problem here?
I've seen abunch of these. The fan motor has a fuse wound into the windings. It cannot be replaced you need a new fan motor. The motors seem to run hot normally, leading to a short lifespan.
I suggest buying a better brand unit.

So I just had this happen with my Frigidaire fad704dwd dehumidifier. I went to basement and heard it running and sounded off. The compressor was running fan was off which is bad and humidity said 30. I then pushed the off button and it stayed running. I was able to fix it. To make long story short it was a bad ground. I took the plastic back, sides, and front off. There was a green ground (main ground) and Green/yellow ground (fan ground) on the front coil with a bunch of rust. Removed the grounds connected them both together and cleaned the surface area and used a new stainless screw nut and screw to remount the wires to evaporator coil. Everything started working fine after that and I put it back together. Good Luck
You may have the humidity level set to high. Usually anything above 50%, will show little results, unless your house is flooded.. Turn the humidity setting to the lowest level that your humidifier has and give that a try.
The fan runs a lot, because it's designed to almost constantly move the air around. That way, if the humidity level rises above the setting on the dehumidifier, it can sense it and the compressor will turn ON.
Check to see if it is clean especially in the coil and fin area, if not that may be your problem. If it is connected by an extension cord loose the cord. If this does not resolve it, then it is a compressor related problem such as a bad relay, possibly a capacitor or the compressor itself. Good Luck, Gil Shultz
Danby dehumidifiers are craps - I have been trying to buy an used dehumidifier. I've looked at several for sale on Kijiji and Craigtslist - the majority of them is by Danby - None of them works. Fan and compressor run but no condesation occurs at the coil i.e. no water dripping into the bucket. Solution: scrap it. Refilling the gas costs more than a new dehumidifier. They are not made for refilling like the compressor in a car.
before you go to fix it, what is the setting it is at? What is the tempurature of the room it is in? If the setting has been satified the unit has done it job and if it is too cold in the room it will not operate properly either.
What is the temperature in the space where you are operating thsi dehumidifier? When you first start a refrigerating system some refrigerant may have condensed into the compressor oil. When the compressor starts the pressure in it drops rapidly. The oil boils and some passes through the compressor valves. After a few minutes of operation this condition normally corrects itself.
Sounds like the unit needs re-gassing and checking for leaks. It is not unusual for a 3-year old unit to require this - especially dehumidifiers as they are often not used all year round, and the seals that stop the gas from leaking are prone to settling and drying out when not in use.
This is not a procedure that you are permitted to carry out yourself, just call a local HVAC/Fridge repairer and see what they quote - the job itself is simple enough depending on the leaks and if anything needs replacing, but the gas itself is getting costly. Make sure they do a leak test first.
If not topped up with gas then don't run the compressor - the lubricant that protects the compressor is mixed in with the refrigerant gas and will dry out quickly if the gas has leaked.
Hope this helps - please ask for more info if you need it :)
