1) checking to verify the dryer was plugged in I inadvertantley could faintly hear that the timer was making sounds so I felt comfortable that it was not the problem.
2) Unplug the dryer and pull the top up, exposing the drum, door switch in the front, heater and two thermostats are on top at the back.
3) Using the continuity tester (not being an electrician the technical term may not be correct) I disconnected the leads to each thermostat and tested for current being able to pass through.
4) The small thermostat about 4" below the larger thermostat on top showed no current. The larger one did BUT the instructions are clear that you need to replace BOTH. That explains only being able to buy the smaller thermostat as a kit, something I initially found irritating. The upper one is supposed to reset itself when tripped but it also trips at a lower temperature than the smaller one. The smaller one is the failsafe. If it trips the larger one has failed to do it's job. Hence, replacement of both is necessary.
5) Two screws at the top of the front plate the door is connected to gets access to the lint collector, fan and part of the bottom of the dryer. If there is a lint collection the airflow is obstructed and the heater will not have cool fresh air flowing through it therefor becoming dangerous. Clean and repair the reason for lint collection.
The whole repair can be completed in under 30 min. if you know what you're doing. If your are looking for advice then I would budget 1-1/2 hrs. One nut drive on your screw driver and a vaccume is all you need but the continuity tester helped isolate the thermostat. There is another thermostat at the fan where the lint collects. All thermostats should be checked.
