Dryer takes longer to dry, doesn't get as hot as before

The most common problem for a dryer to take more than one cycle to dry is restricted air flow.

1.when the dryer is running go outside and find where the venting is located, there should be a good amount of air flow.
2. if the air flow is not good look at the ducting coming from the back of the dryer and make sure it is not kinked or pushed back to far.
there is usually lint build up some where along the ducting or at the end of the duct where it vents to the outside.
3. if you have access to a leaf blower,this can be used to help clear any lint build up inside the duct from the dryer to the outside venting.
move your dryer out and take the leaf blower tube and stick it in the hole and turn it on.
the vented louvers need to be removed from the ouside of the house to allow the lint and things in the duct work to be blown out.
