The short answer
A AGDG dryer that has become noisy is worth diagnosing by the rhythm of the sound rather than by its character. This page covers a single listing, AGDG70U. A noise that repeats once per drum revolution points at the drum path; one that is continuous regardless of drum position points at the motor or the blower.
What you observe
- A rhythmic thump once per drum revolution — Something on the drum path - a flat spot on a roller, a worn glide, or a seam. The rhythm is the diagnosis. On the AGDG roster the check is the same on every listing it covers.
- A metallic rattle that changes with drum speed — Classic blower-housing debris: a coin or a zip pull being thrown around by the fan.
- The drum turns but the noise continues when it stops — Points at the motor or the blower rather than the drum path, because those keep running.
- A flapping or ticking from the back of the machine — A vent flap, a loose duct connection or the duct itself resonating rather than anything internal.
- NEAR MISS - noise plus a burning smell — Stop immediately and isolate the machine. A burning smell on a dryer is a fire risk, not a noise complaint.
Ranked causes
- Coins, buttons or zip pulls in the blower housing — Top of the list because it arrives overnight rather than gradually, and because it costs nothing but access to correct. Across the AGDG listings this is one finding rather than several.
- Belt, tensioner or idler pulley worn — A glazed belt slaps, and a dry idler pulley squeals. Both build gradually and both get worse as the machine warms up. Part numbers differ across the AGDG roster even where the fault does not, so read the table before ordering.
- Machine not level or walking on the floor — The cheapest cause on the page. A dryer on an uneven floor rocks and gradually walks, and the noise reads as internal. Part numbers differ across the AGDG roster even where the fault does not, so read the table before ordering.
- Exhaust duct loose, resonating or flapping — Worth ruling out before any panel comes off, because it is visible from behind the machine.
- Motor or blower wheel failing — A cracked blower wheel belongs here too: it is uncommon, it sounds alarming, and it needs the machine open to confirm.
- Body: Ranked by finding frequency, cheapest to confirm first. The motor sits last because a motor that is genuinely failing usually announces itself by not starting rather than by making a noise.
The order to work in
- Listen for whether the noise repeats once per drum turn — A rhythm that tracks drum rotation points at the drum path; a continuous noise points at the motor or blower.
- Empty the drum and run it briefly — A noise that changes completely with the load out tells you it is load-related rather than component wear.
- Check pockets and the drum seam for trapped items — A coin caught at the drum seam produces a rhythmic tick that mimics a worn roller exactly.
- Body: Work down this list. The levelling and the duct checks cost nothing and are visible from outside the machine, which is where every diagnosis should start.
Before you open anything
Safety
Isolate the machine before any panel comes off - unplug it or switch off its breaker - and remember a capacitor can hold a charge after the power is off. Sheet-metal edges inside a dryer cabinet are sharp, so wear gloves, and stop immediately if a noise is accompanied by any burning smell.

Where the owner line is
The owner line on this roster is the cabinet panel. Levelling, emptying the drum, checking pockets and inspecting the duct are owner work; rollers, belts, idlers and blower wheels all sit inside and need the machine isolated and opened.
