Tumble dryers are the most common type of dryer model, using hot air blown through holes in the drum to dry wet clothing. Occasionally, due to the belt moving constantly during operation of the dryer, the belt will wear out or break, requiring that it be replaced. Replacing the belt on a tumble dryer is a fairly easy job that can be completed in about an hour. You can change the belt yourself and save the time and expense of having someone else do the work for you.
