Another area of frustration is when the dryer stops tumbling. When a dryer does not tumble it is usually a broken belt. Dryers use a belt that goes around the drum and connects to a motor drive shaft. The belt and motor is what turns the drum. If the belt breaks and fails it will stop turning the drum and clothes will not tumble. To check this you will have to open up your dryers' cabinet and inspect the belt. (see video step by step). Replace the belt if it is worn and broken. When you check the belt be sure and observe the idler pulley wheel. The pulley usually wears at the same rate as a dryer's belt and may need to be replaced too.
Other tips on dryers are when they will not start, not heating, drum will not tumble, taking too long to dry or how to get a dryer repaired.
