Understanding the Problem
When a dryer drum doesn't turn, clothes won't tumble and drying times become very long or nonexistent. The issue can be electrical (motor or door switch), mechanical (belt, idler pulley, rollers), or caused by foreign objects obstructing rotation. You can often hear the motor trying to run or see the drum attempt to move when a drive component is failing. Diagnosing quickly saves time and money. Start by checking for obvious obstructions and a snapped belt, then work through the drive system: belt condition and routing, idler bearing, drum rollers or glides, and the motor. For electric dryers, also verify the door switch and start circuit; for gas dryers check the same mechanical components plus that the gas ignition system is functioning (though ignition issues usually allow the drum to still turn).
Common Symptoms
Drum doesn't rotate, loud squealing or grinding when attempting to start, motor hums but drum stays still, burning rubber smell, dryer runs but clothes stay wet.
Common Causes
- Broken or slipped drive belt
- Faulty drive motor or worn motor bearings
- Worn idler pulley, drum rollers, or glides causing drum to seize

Helpful Repair Tip
Open the dryer door, manually try to rotate the drum — if it turns freely the motor/drive is suspect; if it's stiff or gritty, inspect the belt, rollers, or glides before replacing the motor.
Frequently Asked Questions
How do I know if the belt is broken or the motor is bad?
Visually inspect the belt for breaks or glazing and try to spin the drum by hand. A broken belt will allow the drum to spin freely with no resistance from the motor; a hum from the motor with minimal drum movement often indicates a seized roller, bad idler, or a failing motor. Remove the belt and try to run the motor briefly (with caution) to see if it runs freely — only do this if you are comfortable and the dryer is unplugged/reassembled properly for testing.
Can I replace these parts myself or should I call a technician?
Many dryer repairs like replacing the belt, idler pulley, or rollers are doable with basic tools and a model-specific repair guide. Replacing the motor or diagnosing electrical issues may be more advanced and could require a technician if you’re uncomfortable working with wiring or heavy components. Always unplug the dryer (and shut off gas for gas models) before starting any repair.
