A dryer not spinning is two different faults wearing one symptom, and a single question separates them: does the motor run? If you hear the motor and the drum sits there, the drive belt has broken or come off its idler pulley — far and away the most common cause. If you press start and get nothing at all, no hum and no motor, the fault sits upstream: power, the door switch, the start switch, or a blown thermal fuse. Two different repairs, and most pages hand you ten parts without saying which half you are in.
Heat is a separate system, so set it aside. The drum and the heating element are independent, which is why a machine can tumble perfectly and dry nothing — if yours turns but the load comes out cold, you want dryer not heating. This page is about the drum that will not turn.
Two faults, one symptom: what to listen for
Everything a dryer does to turn the drum runs through one chain. The control gives the motor permission, the motor spins a small pulley, a long thin belt wrapped around the entire drum turns it, and a spring-loaded idler keeps that belt tight. Break the chain anywhere and the drum stops. What tells you where it broke is not a part number and not an error code — it is the noise the machine makes in the four seconds after you press start.
So do that first, with the room quiet. Close the door, select a timed cycle, press start, and listen rather than look. A dryer not spinning sorts into one of three boxes on that sound alone.
The check that costs nothing
Open the door and turn the drum with your hand, one full revolution. Five seconds, no tools, and it is the most informative thing you will do today. Maytag puts the baseline plainly: “Typically, the drum should not be difficult to move by hand” (how to fix a dryer that won’t spin). You are feeling for resistance, not for movement.
A healthy drum turns with a little drag, because the belt is wrapped around it and the motor pulley sits on the other end. A drum that spins freely and keeps coasting has nothing attached to it — the belt is broken or off. A drum that fights you, feels gritty or grinds is the opposite fault: a seized roller, a failed rear bearing, or something jammed in the blower.
Motor runs, drum still: the belt and the idler pulley
Both major manufacturers give the identical tell here, which is unusual enough to note. Whirlpool: “You can tell your dryer belt may have worn out if you can hear your dryer motor running, but your dryer isn’t spinning” (10 reasons your dryer won’t spin). Maytag says the same in different words. Put that with a drum that spins freely by hand and you have a diagnosis rather than a guess — a thin loop of rubber holding your laundry hostage.
The belt is not the only thing in that loop, and this is where people buy the wrong part. If it is intact but hanging slack, the fault is the idler pulley that tensions it: a broken spring, a seized wheel, or a belt that jumped off. A slack belt slips instead of turning the drum. One caveat before silence rules the belt out — some dryers carry a belt switch beside the idler arm that shuts the machine down when the belt breaks, so a broken belt can make no noise at all.
Nothing at all: door switch, start switch, thermal fuse
A dryer will not run with the door detected open. That is an interlock, and a worn door switch is one of the cheapest and most common faults on the machine — presenting, unhelpfully, as a completely dead appliance. Maytag: “If the door to your dryer won’t latch, your dryer may not start properly and may not begin to spin.” Whirlpool adds the detail that catches people out: “Be aware that some dryer models have a top and bottom latch, both of which must be secure or your dryer won’t start.”
Test it by observation. Close the door firmly, listen for the click, then open and close it a few times to see whether the machine ever starts. On most dryers the drum light goes out when the switch makes contact, so watch the lamp — a light still on with the door shut is the switch telling you it never engaged. Never wedge, tape or bypass a door switch. Rule out the control lock too, and cycle the breaker fully off and back on rather than looking at it: a partly tripped breaker still looks armed.
Then the thermal fuse, which is why “no heat” and “no tumble” are so often one fault. Whirlpool: “Dryers are mandated to carry a thermal fuse to prevent fires. These fuses are a one-time device: when the temperatures within the dryer get too high, they will go off, shutting down the dryer” (dryer not heating). On many dryers that fuse sits in the motor circuit, so when it goes the machine does nothing.
And a one-time device does not go off at random. Something made the dryer too hot, nearly always a restricted vent — NFPA’s Home Dryer Fires found a third of dryer fires came from a failure to clean. Fit a new fuse into an unchanged duct and you have bought the same repair twice (dryer taking too long to dry).
A hum with nothing turning, and two things nobody checks
A hum means the motor has power and is trying, which rules out the control board, the wiring and the switches before you open anything — the same logic that applies to a washing machine drain pump humming. What is left is something physically stopping it: a seized drum roller, an item jammed between drum and bulkhead, or a motor that can no longer start itself. Do not leave it humming. Switch the machine off.
Two things none of the ranking pages mention. Load matters — a dryer that turns an empty drum but stalls once washing goes in has a slipping belt or a tired idler spring, not a dead motor, so test it both ways. And gas or electric is irrelevant: the drum motor is an ordinary 120-volt motor on both.
What a dryer not spinning is worth repairing
No manufacturer publishes repair prices, and every dollar figure on this subject comes from a page that wants to book you a technician, so this site will not invent one. The shape is safe to state: belts, idler pulleys, drum rollers, door switches and thermal fuses sit at the cheap end and account for most of these machines, while the drive motor and the control board sit at the expensive end — the two repairs both Whirlpool and Maytag hand to a professional.
The convention worth knowing is the 50% rule, reported trade practice rather than measured data: if a repair costs more than half a comparable new machine, replace. A belt never comes near that line. A control board on an older dryer often does.
A seized drum or a second blown fuse ends it here
These are conditions you can look at and confirm, not a sign-off.
- The drum will not turn by hand with the belt slipped off. That is a bearing or a roller.
- You smell burning, or see scorching at the plug, cord or outlet. Off at the breaker, not the switch (dryer burning smell).
- A replaced thermal fuse blows again. The vent is still restricted. Do not fit a third.
- The motor hums, gets hot to the touch, then stops on its own.
- You smell gas near a gas dryer. Operate no switch. Leave, then call your supplier from outside.
Never bypass a door switch, a thermal fuse or a safety thermostat, and never wire around one to test the machine.
FAQ
Why is my dryer running but not spinning?
The motor turns and the drum does not, so the connection between them failed — the drive belt, or the idler pulley that tensions it. Turn the drum by hand: if it spins freely, the belt is broken or off.
How do I know if my dryer belt is broken?
Two signs together. You hear the motor run while the drum stays still, and the drum turns by hand with almost no drag. A drum that resists you means something else failed.
Can I still use a dryer if it doesn’t spin?
No. Whirlpool states it directly: “You may also further damage components of your dryer if you continue to use it if it doesn’t spin.” Clothes sitting still in a heated drum is also how a vent overheats.
Why does my dryer hum but not spin?
Something is physically blocking the drum, or the motor cannot start under load. Seized rollers and a failed start capacitor both do this. Switch it off — a stalled motor gets hot fast.
Can a blown thermal fuse stop a dryer from spinning?
Yes, which surprises people who expect a fuse to affect only heat. On many dryers it sits in the motor circuit, so a blown one kills the machine. Clear the vent before fitting a replacement.
Listen, turn the drum, watch the lamp
Listen, turn the drum by hand, then watch the door lamp. Three checks, under a minute, nothing bought — and between them they sort almost every dryer not spinning into belt, switch or bearing. If the drum spins freely, stop reading and buy a belt.
And if a thermal fuse killed it, the fuse is the message rather than the fault. Same split as a washer that won’t spin: usually a refusal, not a failure, and refusals have reasons you can find.
