My dryer broke today. With the help of YouTube do it yourself videos the $20 heating element is on its way and due to be delivered tomorrow. While I had it apart I vacuumed out the inside and took off the vent hose. The hose has a serious case of heart disease and needs to get on a statin, stat! My dryer vents upward and I have access in the attic to take apart the pipe before it exits the roof. I took it apart and shined a flashlight down. It is also close to 80% blocked. I could reach up and out and clean out the roof exit point but will need to visit Home Depot or get a chimney sweep out for the fixed pipe portion. I guess about 20 feet. Poor ventilation is probably the cause of my heating element giving out. Not sure how close I came to a dryer fire but I will make sure to get it cleaned before I fire up the fixed dryer.
