If your dryer will not spin, first check that the door is firmly latched, the controls are unlocked and the load is not jammed. If the dryer powers on but the drum remains still, a broken drive belt, seized drum support or failed motor is possible. The sound it makes, and whether it attempts to start, can help narrow the next step.
Stop using the dryer if it hums without turning, smells hot or burnt, makes grinding noises, or appears to heat while the drum is stationary. Switch it off and disconnect power if you can do so safely. Never defeat a door switch or operate the dryer with panels removed. If you smell gas, leave the area and contact your gas utility or emergency service from outside.
First: does the dryer start, or does only the drum fail to turn?
A blank control panel and a stationary drum point toward a different problem from a machine that lights up, accepts Start and makes motor noise without tumbling. Look at the display, listen from a safe distance and note whether the cycle begins. Do not keep restarting a humming motor: it may be stalled and overheating.
| What happens | Possible direction | Safe next step |
|---|---|---|
| No lights, no sound and no movement | Power supply or appliance electrical fault | Check normal power connections and the labeled breaker; stop for damage or repeat trips |
| Display works but Start does nothing | Control Lock, door latch, selected setting or control fault | Check lock indicator, close door fully and follow manual’s Start instructions |
| Motor sounds as though it runs; drum stays still | Drive belt or belt-driven mechanism | Stop the cycle and arrange belt/drive inspection |
| Low hum, no drum movement | Stalled motor, jammed drum, blower obstruction or starting fault | Switch off immediately and request diagnosis |
| Drum moves briefly then stops | Overload, motor overheating, support friction or control issue | Remove excess laundry when off; seek service if repeated |
| Grinding or scraping as drum tries to turn | Worn or seized support components | Stop use and arrange mechanical inspection |
Six checks you can make without dismantling the dryer
- Close the door firmly. Remove clothing caught between the door and opening. Some models have more than one latch point. A door that looks closed may not engage its safety switch.
- Check Control Lock or Child Lock. If the relevant indicator is on, use the exact unlock procedure in the owner’s manual. Button combinations vary by manufacturer and model.
- Choose a cycle and press Start properly. Some dryers require you to hold Start for several seconds. A paused cycle may need another press after the door has been opened.
- Reduce the load. Take out heavy blankets or excess laundry and try only a normal, permitted load if no unsafe noises or overheating occurred. LG notes that overloading may prevent proper tumbling on supported models.
- Check normal household power. Look for a tripped labeled dryer breaker and any visible cord damage without opening electrical covers. If a breaker trips again, leave it off and call an electrician.
- Record any displayed code. The exact characters and model number matter. Do not assume a code used by one brand applies to another.
Why the dryer motor runs but the drum does not spin
On many conventional dryers, a belt loops around the drum and is driven by the motor, with an idler pulley maintaining tension. If that belt breaks or slips off, the motor may be audible while the drum does not turn. Some models use a belt switch that prevents starting when the belt fails, so silence does not rule out a broken belt.
A loose, broken or displaced belt cannot be confirmed from sound alone. Internal access varies and may expose sharp panels, electrical components and tensioned parts. Have the correct model-specific belt and drive mechanism inspected before buying replacement parts.
Could a seized drum roller or bearing stop the dryer?
Yes. Depending on the design, a dryer drum is supported by rollers, glides or a bearing assembly. A worn part can start with squeaking or thumping and later produce heavy resistance, grinding or an inability to rotate. A damaged idler pulley or jammed blower wheel may also prevent the motor from turning the drive properly.
If your model’s manual permits it, you can switch the dryer off, unplug it, wait for it to cool and gently check whether the empty drum will turn by hand, without forcing it or reaching past its normal opening. A drum that moves unusually freely may indicate belt trouble; one that resists movement may suggest binding support or drive parts. Neither observation proves a diagnosis. Do not try this if the drum is hot, damaged or difficult to reach safely.
Why the dryer hums but will not spin
A humming dryer may have a motor that is trying to start but cannot. Possible reasons include a mechanically jammed drum, a blower obstruction, worn motor components or a starting-circuit fault. The exact cause requires testing. Continuing to hold Start or repeatedly retrying can worsen an overheated motor or another fault.
Turn the dryer off, disconnect power if safely accessible and book service. Do not push the drum while pressing Start, operate with the door switch bypassed or attempt live electrical testing.
Why the dryer stops spinning in the middle of a cycle
First consider whether the cycle ended normally or was interrupted when the door opened. Some automatic cycles end early with a very small load that does not contact the moisture sensors consistently. This can look like a sudden spinning failure although the motor remains functional.
Repeated stops with a normal load, especially after a hum, unusual heat or burning odor, are different. A motor may be overheating or the appliance may have a power, control or mechanical problem. Stop using it until a technician checks the fault; do not assume a restart is a repair.
Do electric and gas dryers have different no-spin causes?
Many causes are shared because both conventional types rely on a motor and a rotating drum: door switches, control settings, belts and drum supports. Their electrical requirements differ. In North America, many full-size electric dryers use a 208/240-volt circuit; conventional gas dryers commonly use a 120-volt outlet to power the motor and controls. Other markets and compact or heat-pump designs can differ, so use the model label instead of a generic voltage assumption.
A gas supply problem typically affects heating, not the basic motor-driven tumbling mechanism. Never move or disconnect gas piping to investigate a drum that will not rotate.
Should you reset a dryer that will not spin?
A manufacturer-approved restart can clear a temporary control interruption, but it cannot fix a broken belt, seized roller, jammed drum or damaged motor. Use only the reset or restart procedure described for your model. Do not repeatedly reset a tripping breaker, and do not keep restarting a machine that hums, overheats or smells burnt.
When is professional repair the right next step?
Arrange a repair if the dryer has power and its door and settings are correct but the drum still will not turn. Request urgent inspection if the motor hums, the drum grinds, the cabinet overheats or the cycle stops repeatedly. An electrician should handle suspect household wiring or recurring breaker trips; qualified appliance service should handle internal motor, belt, roller, bearing and control diagnosis.
Before contacting a repairer, find the complete model number and record whether the display lights up, whether you hear a hum or normal motor sound, any error code and whether the drum stopped suddenly or became noisy first. Ask for a diagnosis and parts-and-labor estimate before deciding whether repair makes sense relative to the dryer’s age and condition.
Bottom line: check the latch, Control Lock, selected cycle, load and power first. A machine that appears to run but will not tumble often needs its belt or drum drive inspected. A humming or grinding dryer should be switched off rather than repeatedly tested.
