Dryer Not Spinning? Is It the Belt? A Quick Way to Tell

Quick answer
If your dryer is not spinning but you can hear the motor hum or run, the drive belt has probably snapped. Unplug the dryer, open the door and turn the drum by hand. If it spins loose with almost no drag, the belt is the problem. A new drive belt, often a universal one, is a repair many people finish in under an hour, and it costs far less than a service call.
Free fix vs. permanent fix
The two-minute hand test and basic checks
- Unplug the dryer, then open the door
- Turn the drum by hand and feel for drag
- Look for a sock or item jammed behind the drum
- Check that the door latch closes fully
How long it lasts: Not a repair. It shows whether the belt is the cause, so you buy the right part once.
A new drive belt, universal or model-specific
The belt is the only link between the motor and the drum. When it snaps, the motor runs and the drum sits still. Nothing free gets it moving again, but the belt is a low-cost part and the job is mostly screws and clips.
What to get: Universal dryer drive belt
How long it lasts: Years. A fresh belt lasts a long time if the drum rollers and idler pulley are in good shape.

Dryer idler pulley
Replace it if it wobbles or squeals
Why it happens
A snapped or stretched belt
The rubber belt wraps around the drum and the motor pulley. After years of heat and heavy loads it cracks, stretches or breaks. Then the motor runs and the drum stays still.
A worn idler pulley
A spring-loaded pulley holds the belt tight. When its bearing wears, the belt slips or jumps off, often with a squeal first.
A seized drum roller or bearing
If the drum is hard to turn by hand, a roller or bearing may have locked. The belt can slip or burn against it.
A jammed item
A sock or small item stuck between the drum and the cabinet can stop the drum cold.
A failing motor
If the motor hums but the drum will not turn even with a good belt, the motor or its start parts may have failed.

Do these in order, starting with the simplest.
-
Unplug and check the basics
Unplug the dryer. For a gas dryer, also close the gas shutoff if you plan to pull it out. Open the door and look for a sock caught behind the drum or a load wedged against the door.
-
Spin the drum by hand
With the dryer unplugged, push the drum around by hand. A good belt gives some drag and a steady feel. If it spins easily with almost no drag, the belt is broken. If it will not move or grinds, something is seized or jammed instead.
-
Find your model number
Look for the label inside the door opening, on the back, or along the side. Search for the belt by that number to confirm its length and number of ribs. A universal belt fits many models, but check the size against your old belt or the listing's fit list.
-
Open the cabinet
Tool used: Putty knifeMany models open at the top. Slide a putty knife under the seam to release the two spring clips and tip the top up. Others open at the front after you remove screws along the bottom. If the front panel has a door switch with wires, unplug the connector gently.
-
Photograph the route, then lift out the drum
Tool used: Phone cameraTake photos of the belt, the idler pulley and the wiring before you touch anything. Remove the front panel or drum support as your model's guide shows, then lift or slide the drum out. It is heavy, so ask for help.
-
Fit the new belt
Tool used: Universal dryer drive beltLoop the new belt around the drum with the ribs facing the same way as on the old belt. Route it around the idler pulley and the motor pulley as in your photo, push the idler's spring down to slip the belt on, then refit the drum and panel. Vacuum the lint out of the cabinet while it is open. Plug in and test a short cycle.

When free fixes aren't enough
If the drum spins freely by hand and the belt is intact, look at the idler pulley and the drum rollers. A worn pulley or roller can make the belt slip. If the drum is hard to turn, or you smell burning, hear grinding or see melted rubber, stop using the dryer, since the motor or bearings may be failing. If the belt is fine and the dryer hums but the drum will not turn, the motor may need replacing. On a dryer well past 10 years old, weigh that repair against a new dryer. A gas smell means stop and call the gas company.

How we picked: How we picked: this page is based on dryer repair guides, appliance manuals and what owners report in reviews of drive belts and idler pulleys. We do not test products by hand.
Hum, click or silence? What the sound tells you
- Hums but the drum is still: the belt is the most likely cause, or the motor.
- Total silence and no motor sound: check power, the breaker, the door switch and the start switch.
- Loud squeal while it spins: the idler pulley or a drum roller is wearing out.
Safety first inside the cabinet
- Always unplug the dryer before you open it.
- Wear gloves, since metal edges are sharp.
- Do not disconnect a gas line unless you know how. If you smell gas, leave the house and call the gas company.
- Clear the lint while you are inside. Built-up lint is a fire risk.
What to skip
Buying a belt before the hand test, and running it with a slipping belt
Do not buy a belt until the test shows the drum spins loose. A slack belt, a dead motor and a stuck bearing look alike from outside. Also skip running a dryer whose belt is slipping or smells of burning rubber, since the heat can damage the motor.
