This is the 4th Frigidaire dehumidifier I have gotten. For what ever the reason the last two did not last very long; one less than a year and one a little more than a year.  They came up with a code (I cannot remember) and just stop cooling - taking moisture out.  I kept the moisture level at 50%, the basement was always about 67 degrees, and the electrical current was what it was suppose to be so I don't know what the problem is/was. When it worked it worked well. I like them and would buy again but only with the extended warranty which I used on the last two units.
