Query: Item is not working, I will email the seller on Monday

On the 12/21/08 the unit quit working (only 1 month of use). I checked the power source which is ok, the converter light is green but unit light not working. Cannot hear unit running. checked filter and water tank, nothing. I will call seller on 12/29/08. Needless to say I am not a happy customer.
