Re: My electric LG dryer's drum is no longer rotating,...
More than likely the motor fan jammed by a sock (or something of that size) that made it around the lint filter; sucked down into the fan. probably not a belt.

The motors centrifugal switch may be stuck. Try having someone start it while pressing in the door switch while you rotate the drum with your hand by grabbing one of the drum vanes. I don't know which direction your drum rotates. Try both. This may start the drum turning on its own and resetting the switch.
Hello there: If your dryer doesn't tumble, check these: BeltDryers
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 diagramMotorIf 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 switchYour
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.
This is usually the motor but not always. 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, pulley, rear bearing, 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.

A piece of clothing is probably caught in the blower wheel.
Remove lint filter.
Use flashlight to look into filter housing to the lower left.
You may be able to retrive the item if you can see it.
Try rotating the drum in both directions while looking.
Try this:
Unplug the dryer, reach inside the drum and try to rotate the drum 1/4-1/2 turn. Plug the dryer back in a push the start button. Sometimes motors get dead zones in them, and this will move it from that zone.
If that doesn't work, then you will have to go farther.
If you have a front loading machine, remove the front, this will expose the belt and drum, check the belt to see if it is broken, if not then remove the drum and belt and this will expose the motor, idler arm with pulley, Your belt may have slipped off the motor pulley or the idler arm pulley.
Before reassembly, lubricate the drum rollers at the shaft with a good grade of machine oil such as 3 in One Oil.
I hope this helps
Check the dryer breaker pair in the house electrical box. Push off, then on. If the breakers trip immediately, then you have a direct short circuit in the dryer, usually the heating element which involves removing the drum to get at the element(s). If the breakers hold, then try the dryer. If you get heat--ok. If drum turns, but no heat--check with a voltmeter across the two slanted slots in the power socket. You should read ~220 volts AC. If near zero, then one of the breakers is probably bad. Get an electrician to replace the breaker pair.
I have the same problem; pulled it apart and discovered the drum was cracked at the seam where it was welded. the noise occurs as it passes over the wheels the drum rests on. called LG's Cusomer Diservice and nobody was interested. found the same problems by others while searching myself so its clearly a manufacturing problem.
You have a problem with your dryer drum. The seam weld has cracked and the drum needs to be replaced. You will need to call a qualified LG technician to resolve this issue.
