Bad motor overload.
Why would you say that?
Unless I'm missing something even if it happens to be the motor overload that is bad you can not order and replace just the motor overload you need to replace the motor. The new motor will have a new overload on it.
I'm going to say the motor is bad and the overload is doing it's job by tripping the motor out because it gets to hot or draws to many amps.
Replace the motor and you should be good to go.
I looked up your model number and it uses motor part # 279787
This is a very common dryer motor.
