I live in South Louisiana where we typically use air conditioning year round and always have high humidity levels.   As temperatures and electric rates have risen dramatically this summer, I purchased one of those Kenmore 70 pint home dehumidifiers for our apartment.   I knew that if I could lower interior humidity levels substantially that I could raise the temperature on my central air conditioning system and, hopefully, both be comfortable and save on cooling costs.   This unit, which I purchased through an Ebay auction, performed well enough for the first week or two, then problem began to appear.   The unit drew lots of water out of the apartment's air, but it also belched out TONS of HOT AIR out the back!    Not much of a tradeoff.    Then I came home one day to find that the unit had stopped running.   I turned it off, then back on, and was greeted with a horrible sound which I knew was either a bearing going out or a fan squirrel cage hitting something.   Following instructions I found online at Doityourself.com, I removed the back cover, the squirrel cage, and the cooling fan.   The cooling fan was easy enough to clean up, oil, greasel, and reassemble.   This has fixed the cooling fan motor problem, for the time being.   But, there are a litany of problems reported with Kenmore dehumidifiers in particular.    For the time being, mine is running alright again; though my home electric bill actually WENT UP substantially after I began using the home dehumidifier which is supposed to be Energy Star certified!   I've read, though, that, typically, you get ONE SEASON out of one of these things.   I've cross my fingers and see what happens.    Buyer beware!
