Arrived promptly in good condition, our dryer is back in service and I am a hero.  It's important for dryer operation and safety that you take the time to get a cleaning kit and clean the complete run of the dryer vent all the way to the outside of the house.  Poor air flow is one reason why the heater element can overheat and break so it may be trying to tell you something.
