When I turn the dehumidifier 'ON' the compressor kicks 'ON' but the fan stays OFF. Is there a sensor that trips if the refrigerant R-22 is low and does not allow the fan to turn 'ON'? Is there an easy way to check if the refrigerant is too low without dismantling it from its base? Isn't the refrigerant pressurized? Please help. Thanks.

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:

Bring it back for warranty and they will send you a new one. The warranty is 5 years for everything. These LG units have a defective design and I was told the evaporator (or parts thereof) rust and leak. My repair store had rows of LGs in for repair. Most people avoid the hassle and buy another brand. If you have the time to call LG, bring it to a repair shop, wait for an assessment, call back LG for a replacement, you'll get a replacement. But you may have to do it all over again next year -- and until your warranty expires.

SOURCE: Fan will not come on.

The fan has to run if the compressor is running as the fan assists in removing the heat from the condenser coil. Can you spin the fan by hand? If there is full power(120 volts) to the fan and it isn't running then the fan motor is bad. Also, if the fan motor has a run capacitor this could keep the fan from running(if the capacitor is defective) so look for this first.

SOURCE: Hi... my dehumidifier compressor will not turn on,

Sounds like the compressor is inoperative. Most, if not all new units have no means of recharging the freon if it leaks out. If the coils are not cooling, the compressor is not operating and the unit will not dehumidify.
