Direct answer: If your Whirlpool dryer powers on but the drum is not turning, the most common cause is a broken dryer belt. A jammed drum support roller or a failing dryer motor can look similar, so check how the drum feels by hand before ordering parts.
Most likely: Start with the easy tells: remove some laundry, make sure the door is fully latching, then unplug the dryer and try turning the drum by hand. A drum that spins too freely often points to a broken dryer belt. A drum that is stiff or locked usually points to seized support parts or something caught in the drum path.
This one usually comes down to a simple mechanical failure, not a mystery electronic problem. Reality check: when a dryer hums or sounds normal but the clothes never tumble, the belt and drum support parts are far more common than a major electrical fault. Common wrong move: forcing the dryer to keep running while the drum is stuck can overheat the motor and turn a small repair into a bigger one.
Don’t start with: Don’t start by buying a dryer motor or control board. On this symptom, those are not the first bets.
You hear the machine running, but the drum does not tumble and the clothes do not move.
Start here: Start with load size and a hand-spin check with power unplugged. That quickly separates a broken belt from a jammed drum.
You press start and hear a hum or low motor sound, but the drum never gets moving.
Start here: Check whether the drum is stiff by hand. A locked drum path or failing motor is more likely than a belt if it will not budge.
The dryer had been working, then the drum quit turning during a load.
Start here: Let the dryer cool, unload some clothes, and check for a seized roller or motor that overheated under strain.
With the dryer unplugged, the drum moves, but it does not turn when you run a cycle.
Start here: If the drum feels loose and easy, the dryer belt is the first thing to suspect. If it feels normal but the motor only hums, the motor may be failing.
This is the most common reason the dryer seems to run but the drum does not move. The drum often feels unusually loose and easy to spin by hand.
Quick check: Unplug the dryer and rotate the drum. If it spins with very little resistance, the belt is likely off or broken.
A bad support roller can lock the drum path or make it drag so badly the motor cannot get the drum moving.
Quick check: Turn the drum by hand. If it feels rough, binds in one spot, or barely moves, a support roller is a strong possibility.
A bra wire, zipper piece, screw, or other small object can wedge between the drum and housing and stop rotation.
Quick check: Look for scraping marks, a sudden hard stop, or a metallic rub when you try to move the drum by hand.
If the belt is intact and the drum path is not jammed, a motor that only hums or trips out after a few seconds may not have enough torque to start the drum.
Quick check: If the drum turns by hand with normal resistance but the dryer only hums or starts briefly and quits, the motor moves up the list.
A heavy load, a poor door close, or a tripped breaker can mimic a bigger failure. These are fast checks and cost nothing.
Next move: If the drum turns normally after reducing the load or correcting the door close, you likely had an overload or door-latch issue rather than a failed drum part. If the dryer still will not tumble, move to a hand-spin check to separate a broken belt from a jammed drum.
What to conclude: You’ve ruled out the easy false alarms and can focus on the actual drum-drive problem.
The way the drum moves tells you more than the sound alone. This is the quickest way to split the likely causes.
Next move: If the drum spins very freely with little resistance, a broken Whirlpool dryer belt is the leading cause. If the drum is stiff, rough, or locked, look for a jammed object or seized support roller before blaming the motor.
What to conclude: A loose-feeling drum usually means the belt is no longer wrapped around the drum. A tight or rough drum points to drag in the support system or something physically wedged in the path.
A small object caught in the drum path can stop the drum cold and make a good belt or motor look bad.
Next move: If the drum frees up and now turns smoothly, the jam was the problem. Run a short empty test cycle and listen for normal operation. If the drum is still too loose or still binds, the problem is inside the drum-drive system.
By now you should have enough evidence to avoid guess-buying. This is where the likely repair becomes clear.
Next move: If one of those patterns matches cleanly, you can move ahead with the repair instead of replacing random parts. If the clues conflict or you cannot tell whether the belt is intact, the cabinet needs to be opened for a direct inspection or the job should go to a service tech.
Running a dryer with a stuck drum or broken drive parts can overheat the motor and add cost. Once the pattern is clear, act on it.
A good result: If the drum starts smoothly, tumbles evenly, and finishes a small load without strain, the repair path was correct.
If not: If the new belt slips off, the drum still binds, or the motor still struggles, stop and inspect for a bent idler path, damaged drum support parts, or a deeper cabinet issue.
What to conclude: You’ve either fixed the common failure or reached the point where a direct internal inspection is needed before spending more money.

Most often, the motor is running but the Whirlpool dryer belt has broken, so the drum is no longer being driven. If the sound is more of a hum and the drum is hard to move, a seized support roller or failing motor is more likely.
With the dryer unplugged, the drum usually feels much looser than normal and spins very easily by hand when the belt is broken. Many owners also notice the dryer sounds like it is running, but the clothes never tumble.
It may try, but usually only for a moment. You might hear a hum, a weak start, or the motor may shut down from overheating. Don’t keep retrying it, because that can damage the motor.
Start with diagnosis, not parts. On this symptom, the belt is more common than the motor. If the drum spins too freely, the belt is the better bet. If the drum turns with normal resistance but the motor only hums, then the motor becomes more likely.
Yes, especially with heavy wet items. An overloaded drum can stall the drive system or make a weak support part show up. Reduce the load first, then check how the drum feels by hand before assuming a part failed.
That usually points to a broken Whirlpool dryer belt or a motor that cannot start under load. The feel of the drum helps separate them: very loose usually means belt, normal resistance with humming points more toward the motor.
