Quick answer
If your dryer heats but won't spin, the belt is likely broken or loose. Turn off power, check the belt for wear or breaks, and replace if needed. Also verify drum rollers and motor coupling are intact.
Confirm the symptom
- Dryer heats normally but drum doesn't turn
- You can manually turn the drum but it won't spin during cycles
- No unusual noises but motor runs when heating
- Clothes remain damp despite full cycle
Tools and prep
- Unplug dryer or turn off circuit breaker
- Screwdrivers (flathead and Phillips)
- Flashlight for inspection
- New dryer belt (if needed)
- Work gloves to protect hands
- Drain pan for potential spills if accessing components
Step-by-step troubleshooting
- Check Power SupplyDo: Verify dryer is properly plugged in and circuit breaker hasn't tripped.Observe: Dryer powers on and heating element works.Means: Power supply is functional.Next: Check belt condition
- Check Belt ConditionDo: Remove front panel or drum to inspect belt for breaks or looseness.Observe: Belt is intact and snug around drum and motor pulley.Means: Belt is functional.Next: Check drum rollers
- Check Drum RollersDo: Inspect drum rollers for wear or damage. Ensure they rotate freely.Observe: Rollers spin smoothly without wobbling or binding.Means: Rollers are working properly.Next: Test motor coupling
- Test Motor CouplingDo: Locate motor coupling (connects motor to drum) and check for cracks or wear.Observe: Coupling is intact with no visible damage.Means: Motor coupling is functional.Next: Check motor operation
- Check Motor OperationDo: Listen for motor humming while running a cycle. Check for motor overheating.Observe: Motor runs smoothly without unusual noises or heat.Means: Motor is working correctly.Next: Inspect timer or control board
- Inspect Timer or Control BoardDo: Check for visible damage or burned components on timer or control board.Observe: No signs of electrical damage.Means: Control system is likely functional.Next: Consult professional
Common causes
| Cause | Likelihood | Difficulty | Part often needed |
|---|---|---|---|
| Broken or loose belt Belt transfers motor power to drum; if broken, drum won't spin. | Common | Easy | Dryer belt |
| Worn drum rollers Rollers support drum rotation; worn ones prevent smooth spinning. | Common | Easy–Medium | Drum rollers |
| Faulty motor coupling Connects motor to drum; damage prevents power transfer. | Sometimes | Medium | Motor coupling |
| Failed motor Motor may run but not provide enough torque to spin drum. | Sometimes | Hard | Dryer motor |
| Faulty timer or control board May not send correct signals to motor for spinning. | Rare | Hard | Timer/control board |
| Blocked vent or lint buildup Excessive lint can overload motor and prevent spinning. | Rare | Easy | None |
Parts matching
Common replacement parts for this issue include:
- Dryer belt (most common replacement)
- Drum rollers (set of 2–4)
- Motor coupling
- Dryer motor (less common)
- Timer or control board (rare)
Purchase OEM parts for best compatibility with your dryer model.
When to call a professional
- Belt and rollers appear intact but drum still won't spin
- You hear unusual noises from motor or timer
- Dryer emits burning smell during operation
- You're uncomfortable working with electrical components
- Issue persists after replacing all common parts
FAQ
Can I run the dryer without a belt?
No. A broken belt means the drum won't spin, and running it without a belt can damage the motor.
How often should I replace a dryer belt?
Every 3–5 years or when signs of wear appear, depending on usage.
Why is my dryer heating but not tumbling?
This typically indicates a broken belt, worn rollers, or faulty motor coupling preventing drum rotation.
Can lint buildup cause a dryer not to spin?
Severe lint buildup can overload the motor, but this is rare. A broken belt is more likely.
Is it worth repairing an old dryer that won't spin?
If repair costs exceed 50% of a new dryer's price, replacement is usually more cost-effective.
