Why is my dryer not spinning?
A dryer that won't spin is most often a broken drive belt ($100 – $200 repaired) — you'll know it's the belt if the drum spins freely when you rotate it by hand with the door open. If the drum feels locked or resistance is abnormal, the issue is more likely a seized drum bearing or motor failure ($150 – $300).
Drive belt replacement is one of the most common dryer repairs and one of the most affordable. The belt is a long rubber loop that wraps around the drum — it can snap suddenly on any brand after years of heat cycling, and replacing it is well within DIY range if you're comfortable opening the cabinet.
Most likely causes
| Cause | How to tell | The fix | Typical cost |
|---|---|---|---|
| Broken drive belt | Dryer runs and heats, but the drum doesn't rotate; when you open the door and manually push the drum, it spins freely with no resistance at all | Replace the drive belt — the drum has to be removed to thread the new belt around the motor and idler pulley | $100 – $200 |
| Failed door switch | Dryer appears completely dead when you close the door and press start — no motor sound, no heat, nothing; it may work if you press the door switch manually | Replace the door switch — the machine won't run at all if it can't detect the door is closed | $100 – $175 |
| Worn drum rollers or drum bearing | Loud squealing, thumping, or grinding noise when the dryer runs; or the drum won't turn freely by hand and feels stiff or catches | Replace the drum support rollers and/or the rear drum bearing — done at the same time as a belt replacement for efficiency | $125 – $250 |
| Failed drive motor | Dryer hums or buzzes when you press start but the drum doesn't move; drum doesn't turn by hand either (it's locked, not just loose) | Replace the drive motor — a larger repair but still common on machines past 8 years | $200 – $350 |
| Idler pulley seized | Dryer shrieks or screams during operation just before failure; belt is intact but drum won't turn | Replace the idler pulley (maintains belt tension) — often replaced at the same time as the belt | $100 – $200 |
Try this first (before you pay anyone)
- Open the dryer door and try to manually rotate the drum by hand. If it spins very easily with no resistance — almost as if it's floating — the drive belt has snapped. If it's stiff, won't turn at all, or feels locked, the issue is the drum support system or motor.
- Listen carefully when you press Start with the door held closed. If you hear the motor trying to run (a humming or buzzing sound) but the drum isn't turning, the belt is broken or the idler pulley has seized. Complete silence usually points to the door switch or a tripped thermal fuse.
- Check the dryer door switch: with the door open, press the small switch tab near the door frame and see if the interior light goes out (or on — depending on design). A broken switch may prevent the machine from running at all.
- Look inside the drum with a flashlight for the drive belt — if you can see the back wall of the drum and spot a loose, flat rubber strip lying at the bottom, the belt has snapped.
Call a pro when…
- The belt is broken — replacing it requires removing the cabinet panels and routing the new belt around the motor and idler pulley; straightforward for a tech and moderate-to-hard DIY
- The drum is locked and won't turn by hand — a seized bearing or failed motor needs hands-on diagnosis
- You hear grinding or metal-on-metal noise during operation — worn drum rollers or a bearing failure can damage the drum itself if left running
- The dryer motor hums but won't start — motor replacement or a starting component failure needs proper diagnosis before ordering parts
Repair or replace?
Dryers typically last 10–13 years. A drive belt, drum roller, or door switch repair is one of the more affordable appliance repairs — $100–$250 — and is worth doing on any dryer under 10 years old. Motor replacement ($200–$350) on a dryer over 10 years old starts to push against the 50% rule: if the repair quote exceeds half the price of a comparable new dryer (~$500–$900), consider replacement instead. An honest tech will give you both numbers so you can decide.

Related questions
How do I know if my dryer belt is broken?
Open the dryer door and spin the drum manually. If it rotates freely with almost no resistance — like a wheel in the air — the belt has snapped. Normally the belt provides some tension. You may also find the flat rubber strip lying loose inside the drum near the bottom.
How much does it cost to replace a dryer belt?
Dryer belt replacement typically runs $100–$200 including parts and labor. The part itself is $10–$25; the labor is for opening the cabinet, removing the drum, routing the new belt around the motor and idler pulley, and reassembling. It's one of the most economical dryer repairs available.
Can I replace a dryer belt myself?
It's a moderate DIY project — most dryer belts require removing the front panel and lifting the drum to thread the belt. If you're comfortable with basic hand tools and following a disassembly guide for your specific model (YouTube has model-specific tutorials), it's doable. The part costs $10–$25. If you'd rather not, it's a quick and inexpensive pro visit.
Why did my dryer belt break?
Drive belts wear out from years of heat and tension cycling — most belts last 10+ years. Sudden snapping often happens after the drum rollers or idler pulley start to wear and put extra strain on the belt. When replacing the belt, a good tech will also inspect and often replace the rollers and idler pulley at the same time — parts are cheap and the machine is already open.
