[COLOR="Blue"] I replaced the motor, timer, thermal fuse and thermostat and all it does is hum and turn without the drum in when i hold down the start button.[/COLOR]
Sorry but I do not understand the above, could you explain it differently.
The way that I interpret the above is that you get a hum and the motor turns without the drum installed. The hum may be just the normal running noise f the motor.

What was the original problem/symptoms with the unit?
What are the current symptoms?
Looking at the parts you replaced it could be a heating or a motor problem.

Sounds like you either received a bad motor or hooked it up wrong.

See the attachment for the tech sheet.
it should be useful to double check how te motor is hooked up.

The motor should go full speed with the drum out.
Make sure that the unit is set on a non heating cycle when doing this otherwise you could blow a thermal fuse or cutout due to no air flow over the heating coil.
