Moister in the dryer:
This means that the moist air is not escaping correctly and that is why it is taking so long to dry your clothes - if they dry at all.
a good start at cleaning out lint blocked areas, I suggest go to the back of the dryer and take off the vent pipe or hose and check things out with a flashlight. Clean out all the lint and dust you can, even use a vacuum cleaner on it. Make sure the vent pipe is completely clear of any obstructions.
Non-rigid ventshas much worse air flow than smooth piping, so you might want to upgrade to
smooth piping.
Once you have all the lint and dust cleaned out of the dryer, go to where the dryer vents outside. Again, clean the area thoroughly. There is usually a trap door that opens when the dryer air is on and closes when it is not operating. It should be completely clear of lint and opening smoothly.
Also, look into the exhaust area on the dryer carefully to see if there is a hole or gap in the dryer's internal air ducting. Without the vent pipe connected and with no clothes in the dryer, start it and let if run for a few seconds and make sure there is strong air flow from the exhaust port. You should feel it strongly on your hand.
Re-connect the vent pipe and start the dryer again. Feel all around the bottom to see if any air is blowing out from under the bottom. This would indicate there is a break or gap in the dryer's internal ducting. If you do feel air, you will need to call a service technician to see if it can be repaired. If your dryer is very old, there could be a rust hole in the duct.
In conclusion
Cause
·Poor venting is a common reason why water might leak into a clothes dryer. Since the dryer works to expel moisture, it is important that the dryer's vents are properly installed so that the humidity can escape.
Effect
·If the humidity in the dryer is trapped, it will eventually turn to water. This will lead to poor drying results or longer drying times, depending on the amount of leakage.
Prevention/Solution
·Faulty dryer venting can be prevented by making sure that the humidity is directed outdoors. Also, vents should be cleaned of lint and other debris before each load so that water can readily escape. Taking these precautions can ensure that the moisture will meet dry, open air.

Dryer venting issues slow drying, fire flare ups, to hot, noise and clothes ripping etc
A lint filter that is full of lint will restrict airflow and lengthen dry times.
A blower wheel that is not firmly attached to the drive motor can slip and therefore not move air fast enough to properly dry clothes or even reduce airflow to the point where the high limit thermostat may trip and turn off the heat circuit.
In gas dryers, defective gas valve coils can create a symptom of taking too long to dry if they are intermittent. Check for proper flame ignition for the complete dry cycle to determine if this may be the cause.
The drum seals are used to prevent excess air from entering the dryer drum and act as a cushion between the drum and the front and rear bulkheads. The drum seals are made up of a felt like material. If the seal is torn or is worn then clothing can become stuck in the gap when the drum is turning. This can produce a scraping or thumping noise and the clothes can also be ripped and/or have black marks on them.
DOOR SEAL When the door is closed in gas and electric dryers the door seal helps to keep cooler air from entering the drum.
The vent tube or line itself. If it is kinked, smashed, to long, or filled, clogged with lint build up it can not only cause slow dry times but create a fire safety hazard. Try to stay away from using plastic or flimsy cellophane venting, aluminum is best!
To provide better air flow and heat dissipation try the following
Note the length of your dryer vent is a determining factor in how efficient your dryer will perform. If the total length of your pipe exceeds 25 feet then your dryer simply won't be able to perform as should, especially if your pipe runs vertically and through the roof. This is where a booster fan is sometimes needed. Booster Fans provide the extra push of air to exhaust the moisture and lint to the outside. These fans operate only when the dryer is activated, this is done by sensing the air flow through the pipe by a pressure switch mechanism or an electrical sensing relay which in turn activates the booster fan blower. I personally try to avoid adding booster fans simply because they are usually placed in a crawl space or attic and are therefore "Out of sight and out of mind." What I mean is... the unit could malfunction and you would never be aware of it. The result would be a restriction in the pipe which would cause a build up of lint at the fan. In addition, it's recommended that lint traps be placed before the fan itself which has to be cleaned out frequently. These can also easily be overlooked.
IF you do not have an OHM-METER, then you can check these issues by following the directions below:
To check the thermal fuse - You can bypass the thermal fuse (just connect the 2 wires together) for testing purposes only.
To check the thermal cut-out - You can bypass the thermal cut-out (just connect the 2 wires together) for testing purposes only.
To check the thermostats for continuity - - You can bypass the thermostat (just connect the 2 wires together) for testing purposes only.
To check the Element: Try removing element and physically looking at the element wire for a break in the wire.
