Start here
A LG Signature that has become noisy is usually reporting wear in something that turns, or an object where it should not be. Work down the ranking below and note whether the sound keeps time with the drum before touching anything.
What the fault looks like
- A squeal that rises and falls with the drum — A belt or a bearing, and both get worse rather than staying constant.
- A rattle that comes and goes through the cycle — Loose change, a zip or a button tumbling with the load.
- A scraping that is worse with a heavy load — The drum riding down onto something as the load shifts, which points at rollers or glides.
- NEAR MISS — a roar that is really airflow — A duct that has come loose behind the machine makes a noise people take for a mechanical fault.
What goes wrong here, in order
- The machine is not level, or the duct is loose — A dryer that rocks drums against the floor or a neighbouring machine, and a flexible duct that has worked loose behind it roars and vibrates. Stacked machines make both worse because everything is transmitted through the frame. This is the one to start with: how it sits and how it is connected explain most of the noise complaints on a machine like this. LG Signature is the built-in end of the LG range: the same platform lineage, but installed into cabinetry, which changes what can go wrong and what it takes to get at it.
- Lint in the blower wheel — The blower that moves the air can collect lint, a sock, or a scrap of paper. The result is a flapping or a rattle that changes with the airflow, and it usually comes with a machine that has begun to dry slowly as well. Second on this brand: it explains a noise that comes with slower drying, which is a useful pairing.
- Normal operating sounds — A dryer clicks as its thermostat cycles, ticks as buttons and zips tumble past the baffles, and hums with the motor. On a machine that has just replaced a quieter one, every one of those sounds is new and alarming. Third: it is worth eliminating by timing before anything is opened.
- Something in the drum or in the seal — Coins, buttons and underwire escape pockets and lodge between the drum and its front seal. They rattle, scrape and, left there, score the drum surface and snag clothes — which is why this is worth clearing even when the noise is tolerable. Fourth in order: it explains the intermittent rattles rather than the constant noises.
Check in this order, and why
- Push each top corner and check the duct is still connected — Any rock means a foot is short; a duct hanging loose behind the machine roars in a way people mistake for a bearing.
- Note whether the noise came with slower drying — A rattle plus a longer cycle points at the air path rather than at the drum, and that pairing is worth telling a technician.
- Run the machine empty for a few minutes and listen — Noise that disappears with an empty drum was the load; noise that remains belongs to the machine.
The owner checks, step by step
- Level the machine and reconnect the duct properly — Adjust the feet until it does not rock, and make sure the duct is on square with nothing crushed behind the machine.

- Clear the lint filter and its housing, and check the duct — Vacuum the filter slot and the duct connection. A blower obstruction itself is behind a panel and is not an owner job.

- STOP before removing a panel to reach the rollers, the belt or the blower — Live terminals sit behind it and the drum is heavy. Naming the likely cause is the useful end of an owner check.
Safety, before the checks
Safety
Switch the dryer off at its breaker or unplug it before any panel comes off — a capacitor can hold a charge after the power is off. If you smell gas at a gas dryer: do not switch anything on or off, leave the building, and call the gas utility or 911 from outside. Do not look for the leak yourself.
Where the owner's part ends
Call when the drum is empty, the machine is level, the duct is sound and the noise keeps time with the drum — that is rollers, glides or a belt, and all three are behind a panel. Call at once for any smell of burning or gas.

What is deliberately not here
Generalized information. This page covers noise on LG Signature dryers as a class rather than one family or model line; a family-specific page, where one exists, is the more precise answer and is linked above. Not covered here: roller and belt part numbers, disassembly steps and figures that vary between families.
