When an Amana dryer runs but the drum will not spin, the prime suspect is a broken drive belt — and it is easy to confirm. Amana dryers, built on the Whirlpool platform, use a thin belt that wraps the drum and is driven by the motor; with age it cracks and snaps, leaving the motor humming with nothing to turn. The other causes — a worn drum roller, a seized idler pulley, or a motor that has lost its drive — are less common but follow a clear order of likelihood. Here is how to tell which you have.
Quick answer#
Open the door and spin the drum by hand. If it turns freely with almost no resistance, the belt has broken — the number-one cause and an inexpensive fix. If it resists or drags, look at the rollers and idler. If the motor does not even hum, the problem is the motor or its power, not the belt. A drum that will not tumble should be taken out of service until it is repaired, because clothes then sit against the heat.

Confirm the belt first#
The belt test takes seconds and settles most cases:
- With the dryer off, open the door and grip the drum.
- Rotate it by hand. A drum with an intact belt fights back — the belt and idler load it up. A drum that spins loose and floppy has a broken or off belt.
- Listen on a start attempt: motor humming with a stationary, free-spinning drum is the broken-belt signature.
On these Whirlpool-built Amana models — NED4655EW, NGD4655EW, and NED5240TQ among them — the belt is a common wear part and a standard replacement.
Causes by likelihood#
| Cause | Share of no-spin cases | Symptom |
|---|---|---|
| Broken drive belt | 40% | Motor hums, drum spins free by hand |
| Worn drum rollers | 25% | Drum drags, may thump or resist turning |
| Seized idler pulley | 15% | Belt present but binding or squealing |
| Drive motor failure | 10% | No hum, or hum with no attempt to turn |
The remaining share are a failed belt switch (which cuts the motor when the belt breaks on some models) or a foreign object jamming the drum.
Safety First — Know the Risks
Gas dryers carry carbon monoxide and explosion risk. Even electric dryers involve 240V circuits that can deliver a fatal shock. Our techs are licensed and insured — let them handle the risk.

The other causes, in order#
Drum rollers#
The drum rides on support rollers that wear and flat-spot over years. Worn rollers make the drum drag and can produce a thumping or grinding as it tries to turn. If the belt is intact but the drum resists, the rollers are the next check — replaced as a set.
Idler pulley#
The idler tensions the belt. When its bearing seizes, it can bind the belt or squeal loudly, and a badly seized idler stops the drum. It is usually replaced alongside the belt since both are accessed together.
Drive motor#
If there is no hum at all, or the motor hums but makes no attempt to turn and the belt is fine, the motor may have failed. This is the least common and the most involved of the group, and a technician confirms it before replacing.
Which causes need a technician#
- Motor failure — diagnosed and replaced with the cabinet open.
- Belt, rollers, idler — mechanically straightforward but require opening the dryer; comfortable DIYers do these, but a technician makes quick work of the whole drive set at once.
Because the belt, rollers, and idler are accessed together, replacing all three while the machine is open is common and prevents a repeat visit for the next worn part.
The Real Cost of DIY
Average DIY attempt: $150-400 in tools you may use once, plus the risk of further damage. Our diagnostic visit costs $0 — we find the problem and give you an honest quote.

Why stop using it#
A dryer that heats but does not tumble concentrates heat on stationary clothes. On both gas and electric Amana models that is inefficient and a scorch or fire risk, so a no-spin dryer should be switched off until it is fixed — do not run it "just to finish the load."
Preventing a no-spin dryer#
- Do not overload the drum; heavy loads accelerate belt, roller, and idler wear.
- Address a new squeal or thump early — it is often the idler or rollers warning before the belt lets go.
- Keep the dryer level so the drum load is even on the rollers.

Frequently Asked Questions#
Why won't my Amana dryer drum spin?#
If the motor hums but the drum sits still, a broken drive belt is the most likely cause — the belt wraps the drum and snaps with age, leaving the motor running with nothing to turn. Other causes are a failed drum roller, a seized idler pulley, or a motor that has lost the drive.
How do I know if my Amana dryer belt is broken?#
Open the door and try to turn the drum by hand. If it spins with almost no resistance and flops freely, the belt has snapped — a good belt gives firm resistance. A broken belt is the classic reason the machine runs but the drum will not move.
Can I keep using an Amana dryer that won't spin?#
No — if the drum will not turn, clothes sit against the heat source without tumbling, which is inefficient and a scorch risk on gas and electric models alike. Stop using it until the belt, roller, or motor problem is fixed.
Is an Amana dryer not spinning worth repairing?#
Usually yes. A drive belt, roller, or idler is an inexpensive part on these Whirlpool-built machines, and the repair is far cheaper than a new dryer on a unit under about ten years old.
