Direct answer: When a Maytag dryer drum is not turning, the most common cause is a broken dryer drum belt. A seized idler pulley, worn dryer drum rollers, or a failing dryer drive motor can cause the same symptom, so check the easy clues first before ordering parts.
Most likely: If the dryer powers on and you hear the motor running or humming but the drum stays still, the dryer drum belt or belt support parts are the first place to look.
First figure out whether the dryer is completely dead, humming without turning, or running with heat but no drum movement. That split saves a lot of wasted time. Reality check: on this complaint, a snapped belt is far more common than a bad motor. Common wrong move: forcing the drum by hand or repeatedly hitting Start can turn a simple belt job into a motor problem.
Don’t start with: Do not start by buying a dryer control board. On this symptom, the problem is usually mechanical, not electronic.
You press Start and hear a low hum or strained motor sound, but the drum never gets rolling.
Start here: Start with the drum by-hand check. A seized idler pulley, stuck dryer drum roller, or tight drum can stall the motor.
The timer advances and you hear normal machine noise or airflow, but the clothes are not moving.
Start here: A broken dryer drum belt is the leading suspect, especially if the drum turns too freely by hand.
It was tumbling, then quit partway through, sometimes with a thump or slap sound first.
Start here: Look for a snapped belt or a support part that locked up and took the belt out with it.
No hum, no tumble, or only a click when you try to start it.
Start here: Confirm the door is fully latching and the dryer has full power before opening anything up.
This is the most common reason a dryer drum suddenly stops turning while the machine still powers on. Many owners notice a slap or thump just before it quits.
Quick check: Open the door and rotate the drum by hand. If it feels unusually loose and easy, the dryer drum belt may be broken or off.
When one of the support parts binds up, the motor may hum, the belt may burn through, or the drum may feel heavy and rough to turn.
Quick check: Turn the drum by hand with power disconnected. Rough spots, scraping, or a hard stop point to support parts, not just the belt.
If the belt and drum supports are intact but the motor only hums, trips out, or needs a hand-start to move, the motor may be failing.
Quick check: If the drum path feels free but the motor still only hums or overheats, the dryer drive motor moves up the list.
Sometimes the complaint sounds like a no-spin issue, but the dryer is actually not starting at all because of a door latch issue or missing power leg.
Quick check: Make sure the drum light changes with the door, the door catches firmly, and the dryer is not partly powered with a dead leg.
You want to separate a true no-tumble problem from a no-start problem before opening the dryer.
Next move: If the dryer starts and tumbles after firmly closing the door or resetting the cycle, the issue may be a door closure or user-setting problem. If there is still no tumble, move to the by-hand drum check to separate belt and support issues from a no-start condition.
What to conclude: A humming or running sound usually points to a mechanical drag or broken belt. No sound at all pushes you toward door, switch, or power checks before internal drum parts.
The feel of the drum tells you a lot before you remove a panel.
Next move: If the drum turns smoothly with normal resistance, the support parts may still be okay and the belt or motor becomes more likely. If the drum is very loose, suspect a broken dryer drum belt. If it is hard to turn or rough, suspect seized support parts.
What to conclude: Loose usually means the belt is off or broken. Rough or tight usually means a dryer idler pulley or dryer drum roller problem, and sometimes the belt failed because of that drag.
A broken belt is common, visible once opened, and often explains a sudden no-tumble complaint better than an electrical part does.
Next move: If you find a broken or thrown belt and the support parts still spin freely, replacing the dryer drum belt is a solid repair path. If the belt is intact, move on to the support parts and motor checks.
Support parts often fail first, and they can make a new belt fail quickly if you miss them.
Next move: If a pulley or roller is rough, seized, or badly worn, replace the failed support part before putting the dryer back in service. If the drum supports move freely and the belt is intact, the dryer drive motor becomes the stronger suspect.
By now you should know whether you have a straightforward mechanical repair or a deeper failure that may not be worth guessing at.
A good result: If the drum starts promptly, tumbles smoothly, and keeps running through a short test cycle, you found the right fix.
If not: If the dryer still only hums or stalls after the belt path checks out, stop guessing and have the motor circuit and internal components checked professionally.
What to conclude: A confirmed belt or support failure is a practical DIY repair. A motor failure is real on this symptom, but it is less common and worth confirming before spending money.

Most often the motor is trying to run but the dryer drum belt is broken or a support part like the dryer idler pulley or dryer drum roller has seized. A humming sound with no tumbling is a strong clue that something in the drum drive is binding or disconnected.
With power disconnected, open the door and turn the drum by hand. If it feels much looser than normal and spins with very little resistance, the dryer drum belt may be broken or off. Once the cabinet is opened, the belt will usually be visibly snapped, missing from the pulley path, or lying loose.
Yes, but it is not the first thing to assume. If the belt is intact and the drum support parts move freely, yet the motor only hums, overheats, or will not start the load, the dryer drive motor becomes much more likely.
Only if the rest of the belt path checks out. If the dryer idler pulley or dryer drum rollers are rough or seized, replacing only the belt can lead to another failure quickly. Inspect the support parts any time you find a broken or burnt belt.
No. Repeated start attempts can overheat the motor, damage the belt further, or create a burning smell. Once you know the drum is not turning, unplug the dryer and inspect it before trying again.
