Sounds like a bad motor.When they go bad they make a humming sound and sometimes start.Then after a while when they are running the motor gets to hot and there is a overload inside the motor and it stops the motor.After awhile it re sets and maybe it will start again.That is a good dryer but you probably need to buy a new one.All the dryers with lint filter on top are made by whirlpool.It is a very good dryer about 400 dollars.Stay away from G.E or any touch tone products.
