The short answer
On a compact dryer most noise is the cabinet, the mounting or something in the drum rather than a worn part, because the light construction transmits everything. Empty the drum and run it for a minute - that single test separates load noise from machine noise before any tool comes out.
What you actually see and hear
- A rhythmic thump or squeak once per drum revolution — A glide, roller or seal, or something stuck to the drum wall.
- A rattle that changes when you touch the cabinet or the vent hose — Not a fault at all: the cabinet or the hose is resonating against a wall or shelf.
- A scraping metallic sound that comes and goes with the load — A coin, a zip pull or an underwire riding between drum and front bulkhead.
- NEAR MISS - a loud drone with poor drying and a hot cabinet — That is airflow, not mechanics, and it belongs on the heating page.
Causes, most likely first on this machine
- Loose mounting, shelf or vent hose contact — First on a compact machine, and it is the cause a technician visit most often finds. A light cabinet on a worktop drums against anything that touches it, and the vent hose is the usual culprit.
- An object in the drum or trapped at the front seal — Second, because a small drum has very little clearance and coins reach the seal easily. It is free to fix and it is loud out of all proportion.
- Worn drum glides, seal or rollers — Third. Real wear, but slower to arrive on a machine used a few loads a week than the two causes above.
- Blower wheel obstruction — Fourth. Lint and small items get past a compact filter and rattle in the blower, which sounds like it is coming from the drum.
- Motor or belt — Last. Genuine but least likely, and it is the one that cannot be checked without opening the cabinet.
Check in this order, and why
- Run the dryer empty for a minute — Separates load noise from machine noise immediately, with no tools.
- Pull the machine clear of the wall and shelf and run it again — If the noise changes or stops, it was contact and nothing inside is wrong.
- Turn the drum by hand with the power off — Listen for a single scrape or thump per turn and feel for roughness.
- Check the front seal and the lint filter housing — The two places small objects come to rest on a compact machine.
What an owner can safely check
- Empty the drum and run a short timed cycle — Confirms in a minute whether the noise belongs to the load.
About 5 min
- Move the machine away from walls, shelves and the vent hose — Support the hose so it does not rest on the cabinet.
About 10 min
- Check the machine is level and sitting on all four feet — A compact cabinet rocks easily and rocking is loud.
About 10 min
- Clean the lint filter and its housing, and feel round the front seal — Coins and zip pulls collect exactly here.
Tools: torch, soft brushAbout 15 min
- STOP HERE if the noise needs a panel off to reach — Drum glides, rollers and blower work is behind live terminals on this class of machine.
Before you open anything
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 of this class runs on a standard household branch circuit of fifteen or twenty amps, which means a shared circuit is a real possibility - switch off at the breaker, not just at the socket. Never run the machine with the front or rear panel off to watch the drum.
When to call a technician
Call once the drum is empty, the cabinet is clear of everything it might touch and the noise is still there once per revolution - that is a glide, a roller or the blower, all of them behind a panel. Call immediately if the noise arrived with a burning smell or with the cabinet getting hot, because on a compact machine that combination means airflow has been lost and heat is going somewhere it should not. A rhythmic noise with normal drying can wait for a convenient appointment.

What this page does not cover
This page is written for the compact plug-in dryer class, not for one family or model line. Where a brand- or model-specific page exists for your unit it is the more specific answer and it is linked above, so go there first if your machine is named. What is deliberately not here: drum roller and belt part numbers, thermostat ratings, wiring colours and the exact vent kit for your cabinet, all of which differ by family and belong on the page for that family.
