I may be misinterpreting your complaint, but I think your stating that the dryer doesn't dry properly. If so, the first thing I would check is to see if the exhaust duct is clogged with lint (they need to be cleaned out once a year or the ability of the dryer to dry clothes properly diminishes to zero).
What I do is, I disconnect the duct at the back of the dryer and connect a shop vac to the duct. (The kit comes with a shop vac hose-to-duct adaptor). Then I go outside, and using an cordless drill, attach a special duct cleaning brush to the drill (the kit comes with several extension wands to increase its length) and run the brush through the outside cover and down into the duct. The drill spins the brush, completely cleaning the interior of the duct. You can buy the brush at any home center, I bought mine at Menards.

After I'm done, I'll also use the extension pipe on the shop vac and push it up into the dryer itself to clean out that part of the exhaust.
If you neglect to clean the duct, the dryer will eventually take forever to dry clothes and they will still come out damp.
