My dehumidifier compressor runs all the time unless unplugged, the fan doesn't ever run. What's the fix?

SOURCE: Dehumidifier Compressor is not working

this unit is very simular to an air conditioner except it has a humidistat instead of a thermistat.. if your handy with a continuity tester unplug the unit find the humidistat and check to see if its open or if its good then call the company at 1 800 322 3848 or contact the web site at [email protected] Good Luck

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 :)

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.

It sounds like an issue with the control bord. This dehumidifier should have a 5 year warranty through LG. You will need to have this serviced. If it is under warranty by LG they will either refer you to a local repair shop and they will pay for the repair or they will replace it if you do not have a repair shop in your area. Call them and explain the problem to them. Make sure that you have your reciept. Here is the contact information for LG:

unfortunately it sounds as though your refrigerant leaked out. If your compressor is running and no moisture, this is probably the case. What is the temperature of the air coming out?
