Westinghouse Electric Dryer, Drum doesn't turn on start up, if your spin drum and close door it will start,

Either something is binding the blower wheel up or the motor is bad. The best thing is to take the front of the machine off to access the blower wheel to verify ifanything is indeed binding it.IF not read the next section.
If you can turn the drum and then the dryer starts you have a bad motor. The way the dryer works is when you initially push the start button, electricity is sent to the start winding, or stator, of the motor. This will in turn start the motor turning. From there the stator will drop out of the electrical process and at the same time the run winding, or rotor, will take over and the motor will continie to run. Your stator is damaged, has a burn spot, etc so by you turning the drum, the belt around the drum is moved which is attached to the motor pulley. You basically take the place of the stator. Long story short, you have a bad motor.
