The short answer first
On the AGD dryer this symptom is usually the idler pulley, because it spins constantly under belt tension and announces its wear with a squeal long before it fails. The AGD family covers one model number and nothing else, which means there is no revision to identify before ordering a part.
What an owner actually sees
- A fast metallic rattle much quicker than the drum — Blower speed, which means something loose has reached the blower wheel.
- A constant drone from the moment the machine starts — Unchanging noise is the motor rather than anything the drum drives.
- 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.
- 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 AGD family
- Idler pulley worn or its spring tired — Top of the list here. A dry idler bearing gives a high squeal that changes pitch with the drum, and it is the single most common source of the noise people describe as a screech.
- Coin, button or debris in the blower wheel — Second here. It is also the noise that is completely fixed by removing one object, which is why it deserves ranking before anything mechanical.
- Front glides or felt seal worn through — Third on this platform. 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 — Fourth: possible, but not where to start. It is ranked below the cheaper parts because it sounds worse than it usually is, and because it is frequently blamed for an idler.
- Body: A brand-generic article on this symptom starts with the drum support rollers. Here the idler pulley moves ahead of it, because with one model number in scope there is no brand-wide averaging left in the ranking.
The order to work in
- Note whether the noise is a squeal that rises and falls rather than a knock — Pitch that tracks the drum speed is a bearing under tension, which is the idler far more often than the motor.
- Listen for a fast rattle much quicker than the drum rotation — A rattle far faster than the drum is at the blower, and something loose in there needs removing before it damages the wheel.
- 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.
Safety first
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.

Where the owner fix stops
Call promptly for grinding that is getting worse, since a seizing bearing damages parts that are currently fine. Stop using the machine and call if the noise is accompanied by a burning smell or by marks appearing on clothing.
