Dryer Not Spinning: Complete Diagnostic, Fixes & When to Repair or Bin It
You press start on the dryer. You can hear the motor running — a steady hum from the back of the machine. But the drum sits still. You open the door and the clothes are exactly where you loaded them. Or the drum turns for a few seconds and then stops. Or it turns with a light load and stalls the moment you fill it with wet washing.
The good news is that the drum not turning is a mechanical fault, not an electrical one. The heating system and the drive system are separate, and if the motor runs but nothing spins, the fault is in the belt, the rollers, the idler pulley, or the drum support bearing. In the vast majority of cases, it’s a broken drive belt — a $10 to $25 part that takes about an hour to replace on most machines. Motor failure, the fault most people fear, is uncommon and comes last in the diagnostic order.
This post walks through every common cause in order of likelihood, tells you how to test each one, and gives you the repair-or-replace threshold for each. If your dryer turns but won’t heat, or takes multiple cycles to dry, see the full pillar guide: Dryer Repair: Why It Won’t Heat, Won’t Turn, or Won’t Dry →
Quick Checks Before You Open Anything
Before you reach for tools, run through these. They cost nothing and they separate a drive fault from a different problem entirely.
Can you hear the motor running? If there’s a steady hum but no drum movement, it’s a drive fault — carry on below. If there’s no sound at all, it isn’t a drive fault: check the door is fully latched, the door switch clicks, the start button has engaged, and the circuit breaker hasn’t tripped. Electric dryers use a double-pole breaker — if one pole trips, the motor may not run at all.
Is the drum overloaded? A heavy load — towels, bedding, a single duvet — can stall a drum on a worn belt. Remove half the load and run a short cycle.
Will the drum turn by hand? Open the door and push it. A drum that turns easily points to the belt or motor. A drum that won’t budge at all points to a jam or a seized roller.
Is there a foreign object in the drum? A bra wire, a coin, or a small item trapped between the drum and the cabinet will stop it rotating. Check before assuming a part has failed.
Is the drum sagging or wobbling at the front or rear? That points to a worn support bearing rather than the belt.
If none of those resolve it, work through the faults below in order.
1. Broken, Slipped, or Stretched Drive Belt
Why it stops the drum: The belt connects the motor pulley to the drum, held in tension by the idler pulley. It’s a consumable wear item — it stretches, cracks, glazes, and eventually snaps. When it fails, the motor runs freely but nothing turns the drum.
There are three versions of this fault, and they behave differently:
Broken — the belt has snapped. The drum won’t turn at all.
Slipped — the belt has jumped off a pulley rather than snapped, often after an unbalanced load or a jammed item.
Stretched or glazed — the belt is intact but has lost its grip. The drum turns when empty and stalls under a load.
Motor hums but the drum doesn’t turn at all
Drum turns when empty but stops when loaded
Drum turns slowly or intermittently
Burning rubber smell from the rear of the dryer
Belt visible behind the rear panel, broken or off the pulleys
How to test it:
Unplug the dryer and remove the rear panel. Inspect the belt around the drum. Look for a snap, but don’t stop there — check for glazing, cracking, fraying, and stretching too. A belt that looks intact but has lost its grip causes the same symptom as a broken one under load. Check that the belt sits correctly on both the motor pulley and the idler pulley; a belt that has jumped off is a slipped belt, not a broken one.
Cost: Part $10–$25. Labour $120–$180.
Repair or Bin? Repair. It’s the cheapest and most common fix on this list, and always worth doing.
2. Seized Drum Roller
Why it stops the drum: The drum sits on small rollers that support it as it rotates. Their bearings wear with use. A roller that’s rough, stiff, or seized makes the drum difficult to turn — and the belt eventually slips or breaks under the load.
Symptoms:
Loud squealing, screeching, or thumping during operation
Drum stiff or difficult to turn by hand
Drum turns slowly or intermittently
Belt wears quickly or slips repeatedly
How to test it:
Unplug the dryer and access the drum rollers (usually behind the front panel, or by lifting the drum). Spin each roller by hand — it should rotate smoothly and quietly. A roller that feels rough, stiff, noisy, or has play in its bearing has failed. Replace all rollers as a set — if one has worn out, the others are the same age and will follow.
Cost: Part $15–$25 per roller. A full set is $30–$100. Labour $150–$250.
Repair or Bin? Repair. Always worth replacing on any machine.
3. Failed Idler Pulley
Why it stops the drum: The idler pulley is spring-loaded and holds the belt under tension against the drum. If its bearing seizes, or the spring breaks, the belt goes slack and can’t drive the drum.
Symptoms:
Belt intact but slipping — the drum turns slowly or stalls under load
Squealing or grinding from the rear of the dryer
The pulley wobbles or doesn’t spin freely by hand
Belt shows glazing on one edge
How to test it:
Unplug the dryer and access the idler pulley from the rear. Spin the pulley by hand — it should rotate smoothly with no play or grinding. Check the spring is intact and holding tension on the belt. A pulley that’s stiff, noisy, or loose on its shaft has failed.
Cost: Part $15–$25. Labour $120–$180.
Repair or Bin? Repair. Cheap, and worth replacing alongside the belt.
4. Failed Motor or Loose Motor Pulley
Why it stops the drum: The motor drives the belt. If the motor itself has failed, or the drive pulley on the motor shaft has come loose, the belt isn’t driven. This is uncommon — and it’s covered after the belt, rollers, and pulley for that reason.
Symptoms:
Motor hums but nothing moves, then the thermal overload trips
Motor doesn’t run at all, with a known-good belt
Burning smell from the motor area
Motor pulley spins freely on the shaft without driving the belt
How to test it:
Unplug the dryer. First confirm the belt, rollers, and idler pulley are sound — motor failure is only the diagnosis once the mechanical side is ruled out. Check the motor pulley is tight on the shaft and the drive coupling (if fitted) is intact. Measure motor winding resistance with a multimeter and test for voltage at the motor during a start cycle. A motor that hums without turning, with a good belt and a free drum, has failed.
Cost: Motor $80–$150. Motor pulley or drive coupling $15–$40. Labour $200–$350.
Repair or Bin? Repair on any dryer under eight years old. Borderline beyond that.
5. Worn Drum Support Bearing
Why it stops the drum: The support bearing carries the rear of the drum (or the centre spindle on top-loaders). When it wears out, the drum wobbles or sags, the belt tracks unevenly, and eventually the drum won’t rotate freely.
This is the one fault on the list where the repair cost can approach the value of the machine — on some dryers the bearing isn’t replaceable separately, and the whole rear bulkhead has to be swapped.
Symptoms:
Drum wobbles or sags at the front or rear
Loud rumbling or grinding as the drum rotates
Drum feels stiff or binds when turned by hand with the belt off
Belt tracks unevenly or wears on one edge
How to test it:
Unplug the dryer. Remove the belt so the drum is free of the motor, then turn the drum by hand. A drum that still rumbles, binds, or wobbles with the belt off has a bearing fault. Check for play at the rear bearing housing and look for rust or wear.
Cost: Bearing $15–$30 if replaceable separately. Rear bulkhead assembly $150–$300. Labour $250–$400.
Repair or Bin? Worth doing on any dryer under ten years old if the bearing is separately replaceable. If it needs a rear bulkhead, it’s borderline on dryers over eight years old — and usually a bin decision over ten.

Repair vs Replace: The 50% Rule
If the repair costs more than 50% of the price of a new equivalent dryer, replace it.
Typical repair costs:
Cheap fixes (belt, idler pulley): $10–$25 in parts
Medium fixes (drum roller set): $30–$100 in parts
Expensive fixes (motor, motor pulley): $80–$150 in parts
Structural fixes (rear bulkhead assembly): $150–$300 in parts
New dryer cost: $400–$1,200.
When to repair:
Dryer is under 7 years old
The fault is the belt, roller set, or idler pulley
Repair cost is under $150
When to bin:
Dryer is over 10 years old
The fault needs a rear bulkhead assembly
Heat pump dryer with a sealed system fault
Repair cost is over $250
Multiple faults at once
The key distinction: belt, roller, and pulley faults are always worth fixing. A motor failure is worth fixing on a newer machine. Drum bearing or bulkhead failure is the only scenario where the repair approaches the value of the dryer.

FAQ
Why is my dryer motor running but the drum not turning?
A broken drive belt is the most common cause. The belt connects the motor to the drum and is a consumable wear item. Replacement belts cost $10 to $25 and take about an hour to fit.
Why does my dryer drum turn when empty but stop when loaded?
A stretched or glazed drive belt that has lost its grip. It has enough tension to turn the empty drum but slips under the weight of wet clothes. Replace the belt.
Why is my dryer making a squealing noise?
A worn or seized drum roller or a failing idler pulley. Both are inexpensive wear items. Spin each roller by hand — if it feels rough, stiff, or noisy, it needs replacing.
Can I replace a dryer belt myself?
Yes, on most dryers. It requires removing the rear or front panel depending on the model, routing the belt around the drum and pulleys, and reassembling. Check the correct routing for your configuration before refitting.
Why is my Samsung dryer not spinning?
The same diagnostic order applies across brands. On a Samsung dryer, check the belt first, then the rollers and idler pulley. Belt and idler faults are the most common.
Why is my LG dryer not spinning?
Check the belt first, then the rollers. LG dryers also report drive faults as specific error codes — dE, tE, and hE — which the LG guide decodes.
Is it worth repairing a dryer drum that won’t turn?
Usually yes. Belt, roller, and pulley faults are all cheap to fix. The exception is drum bearing failure that requires replacing the rear bulkhead, where the repair cost often exceeds the value of a dryer over ten years old.
