Tip & How-To about Dryers
A dryer is designed to exhaust so many cfm's as it drys through a 4" diameter venting system. The more choked the vent the more heat is backed up into the dryer. This in turn causes the sensors in the dryer to go on and off stopping and starting the heater system in the dyer more frequently then designed. That causes the dryer to take a lot more time and electricity and or gas to dry a load of clothes. Some time 3 or 4 times longer.
Check the flexible dryer vent from the dryer to the wall regularly for kinks and or lint build up.
The major cause of a blocked dryer duct occurs when the water in the clothes is heated to a high temperature and turned into steam, which is then exhausted out the back of the dryer to the outside of the house. As the steam cools on its journey and gets closer to the outside of the house, it tends to get cooler and turns back into water droplets. This is going to be the point where the dried lint, as it escapes past the lint filter, sticks to the newly formed water drops and starts a gradual chocking down of the 4" diameter vent to 3",2",1" and finally stops all flow of air.
Remember, the dryer is designed to exhaust so many cfm's and the more choked the vent the more heat is backed up into the dryer.
It is important to keep the ducting as free from blockages possible. If you are experiencing long drying periods, then it is important to get the lint build up cleaned out.
If you cannot access the dryer ducting, because it is in the wall or ceiling, to look for any obstructions, then look in the yellow pages or contact the local appliance repair service company and get the name of a good duct cleaning company.
Remember to check your venting regularly. A minimum every other year. You will be amazed at how much time and money you will save by doing this simple dryer maintenance.
