If your dryer starts up but doesn't heat, you will need to check the cycling fuse and the heating element. The thermal cycling fuse works as a heat-sensitive safety fuse which is attached to your dryer's heating element chamber. The design is for the fuse to blow when the dryer element overheats. A thermal cycling fuse that has blown will cause your dryer to not activate the heat element. Moreover, in some cases, it may keep the dryer from starting and turning on but rare. If the cycling fuse is bad you will need to replace. If your fuse tests ok, then you will need to check the element coils for continuity.
The dryer part that most people think goes out is the heating element. However, on occasion, the dryer element does go bad but usually it is the fuse. If this is what has happened, then you will need to test the element to see if it has continuity. Continuity means it can carry an electrical current thus creating the warm orange glow to heat your dryer. In addition, an Ohms test gives you a resistance reading. These tests are usually all you need to do to know if you need a new element. If there is no continuity or resistance then you will need a new heating element.
