Hi -- My 2 year old dehumidifier has stopped collecting water and reducing the humidity. I opened it up and:
1) the filter is clean
2) the coils are clean
3) everything is clean
4) the fan works
5) the motor is humming along nicely.

BUT, none of the copper piping is getting cold EXCEPT for one little corner, here ice is building up after 30 minutes of use. (See pic.)

Any ideas how to fix this?

Thanks!http://img641.imageshack.us/img641/1250/0810011253.th.jpg (http://imageshack.us/photo/my-images/641/0810011253.jpg/)

See this troubleshooting guide:

It's probably out of refrigerant and you need to call a certified technician for repair (if it's worthwhile).
