Kenmore 110.72512101 gas dryer

Are you getting little or no lint on the lint screen? Are the clothes coming out nearly as wet as they went in, but feel warm? If so, you probably have a blockage somewhere in the vent/duct. Don't just check the back of the dryer, but also check the duct thru the wall and the point where it exits the house (exterior wall or roof). Many times birds will nest in the exterior vents or if they have a screen to keep the birds out it may become clogged with lint. If you have a window nearby try drying a load with the vent hose disconnected from the wall and hang it out the window (you COULD vent it into the house, but you may end up with lint everywhere and a lot of moisture in your house).
