Although it is relatively rare, heating elements can distort and come in contact with the housing causing an overheat condition which is then remedied by the high temperature safety (thermostat). The wiring diagram which is part of the tech sheet can provide road map for tracing the voltage though the dryer. it all rests within specs. If a dryer is making a loud sound as the burner lights and then turns off after a short time, the air flow could be the cause. There are two “not so obvious” causes of insufficient air flow.
