Not helpful. Why won't this thing just work? The whole point of a dryer is that it heats up and spins your clothes dry. Quickly. You don't have time to rig a clothesline and hang everything up. Today you do, though, because no matter how many times you shut it off and turn it on again, your Kenmore dryer drum simply won't turn. Don't worry. It happens, even to the most reliable appliances. That's where we come in. Whether it's the drive belt or the idler pully, below is a list of the most frequent causes of a stuck dryer. Start at the top and work your way down. When you hit on the cause, we have the replacement part you need, and videos to show you how to replace it.
