Takes a very long time to dry. Not as hot as it used to be.

Hello- It sound like a very common problem and one that you may be able to remedy yourself. It is likely that the dryer is not venting well and the hot moist air is not getting out of the dryer thus taking longer to dry.

• Check the venting at the back of the dryer and make sure the flexible duct is not crushed or crimped. If it is then you can replace it (you can get 4" dryer duct from most hardware stores). Even if it looks ok you should remove it from the dryer and the wall and see if there is a lot of lint build up inside.
• Turn the dryer on and go to the exterior of the house where the vent comes out of the exterior wall and feel how much air is coming out. It should be blowing pretty hard like a fan would. You can also feel inside the vent if possible and see if you feel a lot of lint. Some vents have a little cage over the end to prevent squirrels from getting in there and that can be removed and cleaned. If the air flow is low then you may need to have a duct cleaning service out especially if the vent runs a long distance inside the wall and had many bends.
• A good way to test if the venting is a problem is to run the dryer with the vent detached from the wall inside. It is best to put pantyhose over the end of the duct to prevent too much lint from filling the room.
• If is is still taking a long time to dry you may have an issue with the Operating Thermostat and should have a Tech out to check the heating system.
