Does the noise mostly disappear empty or with a small towel load?
Start outside the cabinet. Level the dryer, reduce load size, remove hard items from the drum, and make sure the feet sit solid.

LG Dryer Making Loud Noise? Check Load, Rollers, and Blower
Start by sorting the sound before you price parts. Run a short empty listen. A thump follows drum rotation. A startup squeal points toward roller or idler wear, and a fast low rattle sends the next check to the blower area.
The usual causes are a heavy or uneven load, loose leveling feet, worn drum support rollers, a rough idler pulley, a damaged belt, or debris in the blower housing.
Use one short empty run, one light towel load, then a hand-turn feel with power off. The result decides whether the repair stays outside or moves inside.
Don’t start with: Do not order a control board, motor, or kit of random parts first. Unplug before opening panels. On a gas dryer, close the gas shutoff valve before moving it, and stop for any gas smell.
Sound firstListen for a once-per-turn thump, startup squeal, scrape, or fast rattle before you remove a panel.
Before openingUnplug the dryer, close the gas shutoff valve on gas models before moving it, and copy the full model number.
Do this first
- Turn the dryer off and unplug it if the noise turns into grinding, scraping, hot rubber, hot metal, burning insulation, or smoke.
- Do not keep running a dryer that gets louder each cycle or makes the drum harder to turn.
- For a gas dryer, close the gas shutoff valve before moving it far or opening access panels. Stop for any gas smell and call the gas utility or a qualified pro.
- Keep hands and tools out of the belt, blower, and drum path while the dryer is plugged in.
- Wear gloves around sheet-metal edges if you open the cabinet.
- Stop if you find metal dust, a seized drum, scorched wiring, or a strained gas connector.
- Do not jump a door switch, thermal fuse, or other safety device to keep testing.
60-second noise sort
Is it a heavy thump once per drum turn?
After load size and leveling are ruled out, a once-per-turn thump usually points to the drum support rollers. Unplug the dryer and turn the drum by hand; a lumpy feel keeps the roller inspection on the list.
Is it a squeal or chirp right at startup?
The idler pulley, drum rollers, and belt path move up the list. Inspect them only after the dryer is unplugged.
Is it a fast rattle or roar from low in the cabinet?
A rattle or roar that runs quicker than drum speed usually belongs near the blower wheel, housing, vent outlet, or debris path. Unplug the dryer and check that area for lint, loose debris, cracks, or rubbing before ordering a wheel.
Do you hear scraping, grinding, or feel drag by hand?
Leave the dryer off. Look for drum support failure, a rubbing belt path, blower contact, or motor trouble before running it again.
Did the sound begin after moving the dryer?
Look behind it first. A crushed vent hose, loose foot, shifted cabinet, or strained gas connector changes the repair path. Stop for gas smell and call a pro.
Use the sound to choose the next safe check
The first photo keeps the diagnosis outside. The close-ups show the two places that earn a teardown: drum support and blower housing. Unplug before either internal inspection.
Before you buy anything
Before ordering rollers, an idler pulley, belt, blower wheel, or motor, copy the exact LG model number from the door frame or cabinet tag. Listen empty and with a small towel load, then buy only when the sound and inspection clue point to one part.
What is probably happening
A loud LG dryer is usually giving you a rhythm clue. Match that clue before the cabinet comes apart.
- A bang or cabinet shake that changes with a bulky load usually starts with load size, leveling feet, or a loose item. Check the drum, level the feet, then try a few damp towels. Noise that drops there stays outside the cabinet.
- A thump or rumble that repeats once per drum turn usually puts the drum support rollers on the list.
- A squeal or chirp right at startup often comes from the idler pulley, rollers, or belt path.
- A fast rattle, flutter, or roar from low in the machine often belongs near the blower wheel or vent outlet. Listen low at the front or rear, then unplug the dryer and look for lint, debris, cracks, or rubbing.
- Scraping, grinding, drag by hand, metal dust, or a hot smell is a stop point. Running it again can turn a support-part problem into belt, motor, or cabinet damage.
- A control board is a late check for this symptom, after mechanical clues and model-specific diagnostics point there.
What not to do first
The wrong first move is usually expensive or unsafe. Keep the first pass simple, observable, and reversible.
- Do not order a control board or motor because the dryer is loud.
- Do not keep running long test cycles after the noise turns into scrape, grind, hot smell, or drag.
- Do not open a panel while the dryer is plugged in.
- Do not spray lubricant into the belt, roller, idler, or blower area.
- Do not run a gas dryer after pulling it forward if the connector is kinked, stretched, or there is any gas smell.
- Do not replace the belt just because the dryer is open; replace it when the belt shows wear.
- Do not buy a part from a photo alone. LG dryer rollers, belts, pulleys, and blower wheels still need model-number matching.
Sound result map
Use this split before you remove screws. It keeps load noise, drum-support noise, and blower noise from getting mixed together.
| What you hear | Likely area | Next safe move |
|---|---|---|
| Bang or shake mainly with a bulky load. | Load balance, loose item, cabinet rock, or leveling feet. | Run a light towel load, remove hard items, and level the feet. |
| Thump or rumble once per drum turn. | Drum support rollers or drum support path. | Unplug the dryer, turn the drum by hand, then inspect rollers if the feel is lumpy. |
| Squeal or chirp at startup. | Idler pulley, rollers, or belt path. | Inspect for a gritty idler, rough rollers, and belt edge wear. |
| Fast rattle, flutter, or roar from the lower front or rear. | Blower wheel, blower housing, vent outlet, or debris. | Unplug the dryer and inspect the blower area for lint, loose debris, cracks, or rubbing. |
| Scrape, grind, drag, hot smell, or metal dust. | Rubbing drum, failed support part, damaged belt path, or motor issue. | Leave it off until the rubbing part is found. |
Outside checks before opening the cabinet
These checks cost almost nothing and often separate a real failed part from load slap or a rocking cabinet.
- Run the dryer empty for 30 to 60 seconds and listen from the front, each side, and low near the blower area.
- Try a few damp towels, not a packed load. A big change in sound points back to loading instead of a failed roller.
- Pause the dryer, wait for the drum to stop, unplug it, and rock the cabinet gently corner to corner.
- Adjust the leveling feet until all four feet sit solid and the cabinet no longer twists on the floor.
- Look inside the drum for coins, screws, zipper pulls, bra wires, or anything caught in a baffle or seam.
- Make sure the lint screen seats flat and the front drum felt is not visibly loose or folded into the drum path.
- Look behind the dryer for a crushed vent hose, a loose clamp, or lint around the outlet. Vent restriction is not the usual cause of a drum thump, but it can add blower noise and heat.
Internal clues that justify parts
Open the dryer only after the outside checks fail. Once you are inside, look for the part that matches the sound instead of replacing everything in reach.
- Unplug the dryer first. On a gas dryer, close the gas shutoff valve before moving it far enough to stress the connector.
- Take a photo of the belt path before lifting the drum or moving the idler. That photo saves time during reassembly.
- Drum support rollers earn replacement when they have flat spots, cracked rubber, wobble, rough bearings, or dark rubber dust around the shaft.
- An idler pulley earns replacement when it squeals, feels gritty, wobbles on its shaft, or has a glazed groove where the belt rides.
- A belt earns replacement when it is frayed, cracked, glazed, stretched, or edge-worn. A healthy belt can stay.
- A blower wheel earns replacement when it is cracked, loose on the shaft, rubbing the housing, or still rattling after debris is removed.
- Motor diagnosis comes later, after the drum support, belt path, and blower wheel spin smoothly and the motor itself is still noisy.

Why is my LG dryer suddenly so loud?
A sudden loud noise usually means something mechanical changed fast. The load may have shifted, the cabinet may be out of level, or a roller, idler pulley, or blower wheel may have changed. Electronics are not the first place to spend money for a noise complaint.
What does a bad dryer roller sound like?
Bad dryer drum support rollers usually make a repeating thump, rumble, or low growl that follows drum rotation. Run a short empty listen, unplug the dryer, then turn the drum by hand. If the noise stays empty and the drum feels lumpy, inspect the rollers for flat spots, wobble, cracked rubber, or dark dust before buying a kit.
What does a bad dryer idler pulley sound like?
A bad dryer idler pulley often squeals, chirps, or makes a sharp rubbing sound right as the drum starts moving. Unplug the dryer before opening the cabinet. A pulley that feels gritty, wobbles on its shaft, squeals by hand, or has a glazed belt groove is a supported replacement clue.
Can a clogged vent make an LG dryer noisy?
A clogged or crushed vent can add heat, strain, and odd airflow sounds, but it usually does not cause a once-per-turn thump by itself. Still, inspect the hose and outside exhaust because poor airflow can make blower noise and overheating worse.
Is it safe to keep using a noisy dryer?
Do not keep using it if the noise is getting worse, the drum scrapes, the cabinet smells hot, or the drum is hard to turn. A worn roller, idler pulley, belt, or blower wheel can damage nearby parts if it keeps running.
Should I replace the belt when I replace rollers or an idler pulley?
Replace the belt if it is frayed, cracked, glazed, stretched, or edge-worn while the dryer is apart. Skip it if the belt looks healthy and the noise is clearly from a roller, idler pulley, or blower wheel.
How do I tell blower wheel noise from drum roller noise?
Blower wheel noise is usually quicker than drum rotation and often comes from the lower front or rear blower area. Listen low during a short run, then unplug the dryer and check the blower area for lint, debris, cracks, or rubbing. Roller noise follows the slower drum rhythm and often shows up as a once-per-turn thump, rumble, or lumpy hand-turn feel.
Can an uneven load make the dryer sound broken?
Yes. Heavy towels, shoes, or a mixed load can slap the drum and rock the cabinet. Listen empty for 30 to 60 seconds, then level the feet and try a small damp towel load. If the noise drops sharply, stay with load balance and leveling.
When should I call an appliance tech?
Call for service if there is any gas smell or burning insulation odor, if you see scorched wiring, or if you find metal dust from hard scraping. Service also makes sense when you cannot move a gas dryer safely or the motor is noisy after the drum and blower spin freely.
