If dryer does not spin it is usually a problem with the belt or the motor. Check also door switch.

If your dryer doesn't tumble, check these:

Belt
Dryers
have a drive belt that turns the clothes drum. If the belt breaks, the
drum stops rotating. Then you need to replace the belt, and often the
idler pulley, because the pulley tends to wear out at the same time.

Motor
If the dryer motor only hums when you press the Start button, the motor may be burned out. Here's how to test the dryer motor:
- Remove the belt.
- Check for obstructions in the blower fan housing.
- Manually rotate the shaft of the motor.
If
the motor is very stiff, or impossible to rotate manually, and the
blower fan housing is clear, you need to replace the motor.
If
the motor rotates freely, run the motor momentarily with the belt
removed and the blower in place. If the motor runs fine with the belt
removed, there may be a problem with the idler pulley or the clothes
drum. Try to rotate the drum by hand. If it is very difficult to move,
correct any problem with the rollers or pulley, and then reassemble the
dryer and try it again.
If the motor hums but doesn't rotate on
its own even with the belt removed--yet you can turn it freely by
hand--you usually need to replace the motor or the motor start
capacitor.
Door switch
Your
dryer can't operate at all if the door switch is defective. It's inside
the dryer main housing near the door frame. Sometimes you need to raise
or open the top or front of the dryer to reach the switch. If it's
defective, you need to replace it.
