Quick answer
A dryer that runs but will not tumble has usually broken its drive belt; the drum turns freely by hand with no resistance. A loud hum with no movement points to a seized drum roller or idler pulley, or a failing motor. Unplug the dryer, turn the drum by hand, and check the door switch. Angi puts typical dryer repairs at $100–$430, about $180. Call (888) 217-0236 to reach an appliance repair company taking calls in your ZIP; the line is answered 24/7.
Follow the short menu, then your 5-digit ZIP. The line goes quiet for a few seconds while it connects; stay on. If it does not connect, call once more: companies taking calls change minute to minute.

A dryer that runs, and maybe heats, but whose drum does not turn has usually lost its drive belt. If the motor hums and the drum still will not move, the problem is more often the motor, a seized roller or something jammed. The sound it makes when you press Start tells you which.
Listen When You Press Start
| What you hear | Likely cause |
|---|---|
| Motor runs normally, drum does not turn | Broken drive belt |
| Loud hum, no movement | Motor cannot start: seized drum roller or idler pulley, failing motor or start switch |
| Drum turns by hand very freely, no resistance at all | Broken belt |
| Drum will not turn by hand | Seized roller, item jammed between drum and front panel |
| Nothing at all | Power, door switch or thermal fuse; see dryer won't turn on |
Check These First
- 1Unplug the dryer before reaching into the drum.
- 2Turn the drum by hand. Spinning with no resistance means the belt is off or broken. Stuck solid means something is jammed or a roller has seized.
- 3Check the door switch. On many dryers the motor will not run with the door switch open; press it with a finger and listen.
- 4Do not keep pressing Start on a humming dryer. A motor that cannot turn overheats.

Why Belts Break
Belts stretch and crack with age, and break sooner when rollers or the idler pulley are worn and drag. A good repair checks all three. A thumping or squealing dryer before the drum stopped is a sign the rollers were going; see dryer making loud noise.
What a Repair Costs
Angi puts typical dryer repairs at $100 to $430, about $180 for the average job; Fixr puts the national average at $100 to $200. A belt with rollers and an idler pulley is a common, mid-range job. A motor is at the high end. See dryer repair.

Why does my dryer run but the drum won't turn?
The drive belt has usually broken. If the drum spins by hand with almost no resistance, that confirms it.
Why does my dryer hum but not spin?
The motor is trying to start but cannot turn the drum, often because a drum roller or idler pulley has seized, or the motor or its start switch is failing.
How much does it cost to fix a dryer that won't tumble?
Angi puts typical dryer repairs at $100–$430, about $180. A belt with rollers and a pulley is a common mid-range job; a motor is at the high end.
