Why does my dryer keep blowing thermal fuses?

A month ago my dryer stopped working. It would not even start when I pressed the button. I pulled several parts and tested them for continuity using a multimeter. The thermal fuse was bad so bought a new fuse and it came with a new high-limit thermostat. I replaced the thermostat and fuse. I also did a thorough cleaning of the inside of the dryer to remove lint. I also fixed a slight kink in the dryer hose that may have contributed to the fuse failing. The dryer worked fine for a month then I had the same problem ( the dryer simply wouldn't start). My daughter admitted that she may have neglected to clean the lint filter a couple of times. I pulled the thermal fuse and tested it; it was bad. So I bought another fuse and thermostat and put them in the dryer about 4 days ago. Now the dryer has stopped again. So, any ideas on what might be causing these fuses to fail?
