Why a dryer can heat when the drum won’t turn
On many dryers, the heat only switches on while the drive motor is running. So heat usually tells you the motor is running. The same motor usually turns the blower fan, so air still moves and warms up. The problem is between the motor and the drum: the belt, the idler pulley that keeps the belt tight, or the rollers the drum sits on.
Some dryers have a belt switch that stops the motor, and so the heat, when the belt breaks. Those dryers go completely dead instead. If yours heats with a still drum, it probably doesn’t have one, or the drum is jammed rather than the belt broken.
- Drive belt wraps around the drum. If it breaks, the drum spins freely by hand.
- Idler pulley keeps the belt tight. If it seizes or breaks, the belt slips or snaps.
- Motor turns the belt and the blower. On many dryers the heat only runs while the motor runs.
- Drum rollers carry the drum. Worn ones thump, squeal or drag.
First checks (no tools needed)
- Is it a pause, not a fault? Wrinkle-prevention options (for example Whirlpool’s Wrinkle Shield) tumble the drum only now and then after the cycle ends. Cancel and start a normal timed cycle.
- Is the door fully closed? Close it firmly; you should feel the latch engage. On most dryers an open-door switch stops the drum.
- Did you start it properly? Whirlpool notes that Start, Push to Start or Hold to Start buttons should be pressed and held for two to five seconds.
- Is it overloaded or jammed? Remove the load. A very heavy load, or an item wedged between the drum and the front (a bra wire or sock), can stop the drum. Check around the drum edge with the dryer unplugged.
- Listen. Start it empty for a few seconds. A hum with the drum still, then silence, can mean a jammed drum or a motor that can’t start. A normal running sound with the drum still points to the belt.
⚠️ Caution: unplug first, and leave gas lines alone
Unplug the dryer before you touch the drum, the door switch or any panel. On gas dryers, don’t strain or disconnect the gas line when you move the dryer; if it must be disconnected, have a qualified person do it. Sheet-metal edges inside the cabinet are sharp, so wear gloves. Never run the dryer with a panel off or a switch bypassed.
The hand-turn test
Unplug the dryer first (for a gas dryer, unplugging is enough for this test; you don’t need to touch the gas line). Open the door and turn the drum by hand.
| How the drum turns | What it usually means |
|---|---|
| Spins very easily, almost freely | Broken or slipped-off drive belt. With the belt on, the drum takes noticeable effort to turn. |
| Normal effort, but it scrapes, thumps or squeals | Worn drum rollers, drum glides or the idler pulley |
| Stiff or won’t move | Something jammed, a seized roller, or a blower wheel blocked by debris |
Parts supplier Repair Clinic gives the same test: if the drum “spins too easily the belt has probably failed.” It lists the belt, drum rollers, roller axles, idler pulley, blower wheel and (rarely) the timer as the causes of a drum that won’t turn. Source: Repair Clinic: dryer drum not turning.
If it’s the belt
A broken belt is the most common cause and a common owner repair, but it means opening the cabinet. The panels you remove, and how the belt threads around the idler pulley, differ between models. Before you start:
- Unplug the dryer. On gas models, don’t strain or disconnect the gas line when moving the dryer; if it needs disconnecting, have a qualified person do it.
- Get your model number from the label (usually inside the door opening) and order the belt for that model.
- Use the manufacturer’s service or parts diagram for your model to see how the belt routes. It usually goes around the drum, ribbed side in, then around the idler pulley and the motor pulley.
- While it’s open, spin the idler pulley and look at the drum rollers. A seized pulley or flat-spotted rollers often cause the belt to break, so replacing the belt alone may not last.
- Remove lint from inside the cabinet while it’s open.
- Refit every panel before plugging the dryer back in. Never run it open.
If you’re not comfortable opening the cabinet, a technician can do this quickly, and the part itself is usually inexpensive.
Rollers, glides and the idler pulley
A drum that turns only with effort, or thumps or squeals, usually has worn rollers or glides. A failed idler pulley lets the belt go slack, so the motor runs without turning the drum. These parts are model-specific. Replace them in sets where the manufacturer recommends it.
The belt isn’t broken, so why won’t it spin?
If the belt is intact but the drum still doesn’t turn, look at what the belt runs on. Repair Clinic’s list of causes for a drum that won’t turn covers the belt, the drum rollers and roller axles, the idler pulley and the blower wheel. In practice:
- Belt intact but loose, or off the pulleys: the idler pulley has failed or its spring has let go, so the motor turns without gripping the belt.
- Belt intact and the drum is stiff: a seized roller, or something jammed between the drum and the front or rear panel.
- Motor hums but nothing moves: a jammed drum or blower wheel, or a motor that can’t start. Stop and call a technician; don’t keep restarting it.

When to call a technician
Call a technician if the drum is stiff or locked, if the motor hums without starting or makes a burning smell, or if the breaker trips. Also call one if you don’t want to open the cabinet. Don’t bypass a door switch or belt switch to “test” the dryer. Useful details: the model and serial number, the hand-turn result, what you heard, and whether it’s gas or electric. Print the checklist.
Frequently asked questions
Is it safe to use a dryer that heats but doesn’t spin?
No. With the drum still, the same clothes sit against the heated air flow and can scorch. Stop using it until it’s repaired.
How do I know if it’s the belt or the motor?
Unplug it and turn the drum by hand. A drum that spins very freely usually means a broken belt. If the dryer heats at all, the motor is usually running, which also points away from the motor.
Why did my belt break?
Belts wear out with age, but a seized idler pulley, worn rollers or overloading speed that up. Check those parts when the belt is replaced.
How much does it cost to fix a dryer that’s not spinning?
Fixr lists $150 to $250 for a belt replacement, $100 to $150 for drum rollers and $250 to $450 for a motor, plus a $50 to $80 diagnostic visit.
The motor runs but the drum doesn’t turn. What is it?
Usually the belt has broken or slipped off, or the idler pulley has failed. Unplug the dryer and turn the drum by hand: if it spins very freely, it’s the belt.
