When you say it won't turn all the way on, does that mean the drum isn't rotating?

If yes, the belt from the motor that goes around the drum might have broken and you can hear the hum of the motor spinning but no longer rotating the drum.

The other thing I can think of is that the motor itself has failed, possibly seized, and you can hear the motor trying to spin but it cannot. With the dryer unplugged and empty of clothes, try to rotate the drum. If it rotates extreamly easily, then the belt has broken. If you cannot rotate it at all by hand, then chances are the motor is seized. It should rotate with moderate effort.

If Dryer does not tumble , check the following:

" It won't tumble If your dryer doesn't tumble, check these:

Belt
Motor
Door switch
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.

Click here for a belt installation diagram.

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."Source Repaiclinic

ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Sounds like your problem may be a broken belt, or the belt may have slipped off of the motor pulley, or idler arm pulley.
If you have to replace your drum belt and if you have a front loading machine.
Remove the electrical console that holds the timer switch, start switch, etc. from the top of the dryer. Be real careful not to knock any of the wires off of the timer switch. Then remove the top of the dryer.
Remove the front of the machine, this will expose the belt and drum, remove the drum and belt and this will expose the drum rollers, idler arm bracket with pulley, and motor with pulley. Pay attention to the route of the belt, this will come in handy when you go to reinstall the belt and drum.
Sometimes the belt will slip off of the idler arm or motor causing the drum not to turn.
While you have the drum out, I would recommend that you lubricate the drum rollers at the shaft of the roller with a good grade of machine oil like 3 in One oil. This will save you a problem later with the rollers getting noisy, also check your drum rollers for flat spots, if they have flat spots on them this will cause a noise like a thumping type noise. You will need to replace the drum rollers if they have flat spots on them.
I will include these two websites for parts and further help:

Check to see if the drum will turn by hand. If so, leave the door open but push the light switch button down and start the unit. Once you hear the humming sound, manually turn the drum with your hand to start. If the drum turns normally, you have a bad motor and needs to be replaced. If the drum does not turn, something is jamming the motor and needs to be disassembled and inspected.
Good luck
