The dryer is about 3 years old. We just moved into a new house about 3 months ago. The dryer worked fine until about 6 weeks ago. The clothes are still damp and hot after about an hour with different load sizes and types. All loads take about 2 hours to completely dry. The vent is clear from the lint filter through the duct in the dryer all the way to the wall. The venting system goes straight up through the roof with no problems. All connections are good and you can actually feel the air flow. The pipe is warm to the touch. I've checked continuity in all the fuses, thermostats, and the element. I even checked the thermostat on an electric griddle. The voltage is good to the receptacle and the breaker is good. Any ideas?
