Problem drying clothes

This is the classic symptom of "poor air flow". Another symptom you didn't mention (but I bet is happening) is that the top of the dryer gets VERY hot. OK, don't move your dryer yet... get a flashlight and look behind there. See the flexible vent connecting the dryer to the wall? It must have SMOOTH, FLOWING turns. No crushing allowed. If it's crushed/pinched, you found the problem. It's "choking" off the air flow... not allowing the hot air to escape and containing all of it in the dryer cabinet. If this is the problem, pull the dryer away from the wall about 8" and make sure the vent isn't pinched off anymore. Leave your dryer this far out, it'll ensure that this doesn't happen again. If the flexible vent is OK, there is a blockage in your house's internal dryer duct work somewhere. Turn the dryer on and go outside to where the exhaust is. Check air flow. Check the exhaust vent for debris (I've seen birds build nests in the outside exhaust, incubates the eggs...but your clothes won't get dry!). If your dryer location and the exhaust location are quite a distance (20' or more) from each other, you should hire a professional to come out and thoroughly clean it out for you. In this case, you should have this done once a year as part of routine Home maintenance. To test and verify my solution to this, you can remove the dryer vent from the wall and cover the end of it with a pair of old pantie hose. Then run the dryer as usual (the pantie hose will act as a secondary lint trap). You'll see that the dryer will be happy again and the clothes will dry in no time at all.
