What this means on these models
On the NEC dryer this symptom is usually the drive belt, because a belt that has begun to fail makes noise for weeks before it breaks and strands the machine. The NEC family spans more than one size or configuration code, and those differences change the parts rather than the order of the checks.
What you observe on these models
- Scraping, with grey marks appearing on light clothing — Front glides or felt worn through to metal.
- A deep grinding that has got worse over months — The one noise here that tends to end with a seized drum if it is left.
- A thump that changes when the machine is moved — Levelling and floor, which is not a fault at all.
- A rhythmic thump in time with the drum — Once per revolution puts it at the drum supports or the belt, not at the motor.
- NEAR MISS — a loud bang and then the drum stops turning — A noise that ends in no rotation is a broken belt or a seized part, and the will-not-start page covers what to do next.
Causes, most likely first on the NEC family
- Drive belt frayed, glazed or starting to part — Ranked first on this family. Taking the noise seriously at this stage is the difference between a planned repair and a load of wet washing.
- Front glides or felt seal worn through — Next, and close behind it. Worn glides give a scraping or rubbing noise that is constant rather than rhythmic, and they often leave marks on clothing as well.
- Drive motor bearing worn — Next after those two. It is ranked below the cheaper parts because it sounds worse than it usually is, and because it is frequently blamed for an idler.
- Machine not level or walking on the floor — Fourth, and the least likely of the four. A short foot or a springy floor produces a low-frequency thump that changes completely when the machine is moved a few inches.
- Body: A brand-generic article on this symptom starts with the drum support rollers. Here the drive belt moves ahead of it, because the size codes in this family share a subsystem, and that shared subsystem is where the failures concentrate.
What to check first, and why that order
- Listen for a soft repeating slap that keeps time with the drum — A soft, regular thump with no grinding is usually belt rather than bearing, and the belt is the cheaper part.
- Look for scorch marks or grey scuffing on light-coloured washing — Marks on clothing alongside a scraping noise names the front seal without opening anything.
- Note whether the noise is constant or keeps time with the drum — Constant and unchanging is the motor.
Before any panel comes off
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. A dryer is heavy and its cabinet edges are sharp, so get help before moving it and never reach into a drum or a blower while power is connected. If the machine is gas-fed, do not move it far enough to strain the flexible connector; if you smell gas, leave the building and call the gas utility from outside.

When this becomes a service call
Stop using the machine and call if the noise is accompanied by a burning smell or by marks appearing on clothing. Call when the noise survives the free checks — levelling, panels pressed, machine run empty — because the rest is behind the cabinet.
