Dehumidifier only two years old now doesn't

Problem is that you bought a dehumidifier made by the Korean/Chinese manufacturer LG.
Search the web and you will find that you are just one of many whose dehumidifier worked the first year but now draws no water out of the air even though it makes all the right fan and compressor noises.
Most common problem is that all the Freon refrigerant escaped, apparently because the copper tubing cracked and leaked. Penguins beware, there goes the Ozone Hole!
It cost me $14 and an afternoon of investigation and testing of my LG 504EL dehumidifier to figure this out. The fix-it web site "Just Answers" said that it wasn't worth fixing after I described all the symptoms. Tomorrow I will go to the local LG fix-it shop and try to get a replacement to tide me over until I can find a reliable dehumidifier.
Sadly, last Fall I took my 25 year old Westinghouse (made in America) dehumidifier to the dump. Even though it needed me to tune it up every year or two, at least I could fix it and it kept on working for 25 years.
Good luck!
