Ok so I'm with scrapiron on this issue. With the majority of electric dryers, the high limit thermostat and thermal fuse are both safety critical components. They keep the heating element operating in a range where things will tend not to catch fire. When the thermal fuse blows, it's because the high limit thermostat was lazy.
These two components are different between models and brands for the same reason. Don't try to amp up a Samsung or Frigidaire dryer by changing out components from a whirlpool duet dryer. It could dry faster and not pop thermal fuses, but eventually the thing could burn down a laundry room somewhere.
Even on pretty new unit, I swap out the high limit thermostat and thermal fuse together. New and matched is a good way to eliminate repeat service, as well as a look see at the outlet of the dryer vent.
