Dryer takes too long to dry!
Also check the lint trap, if you use fabric softening sheets. The lint trap can become plugged from the build up of the fabric softener material. If you run watter though it it should flow pretty freely and not significantly. I've never had this problem myself, only about read it. Hopefully, I'm not just spreading an urban myth. But the first check would be to check the exhaust while running. If you can compare it to a neihbors, great. If the flow seems low or near non exisitant, you now know your problem and just have no figure out the cause. IS it the fan or pluging of the vent or lint trap.
