LG dryer making noise: identify the phase. Noise during tumbling = drum rollers or glides worn. Squealing = belt or idler pulley. Rattling = loose object in drum or blower wheel debris.
When I get a call for a noisy LG, I usually check the drum rollers first because they tend to flatten if the dryer sits for a while with a heavy load. Ignoring these sounds can lead to bigger problems like a snapped belt or a burnt-out motor. Fixing it early usually saves you a few hundred dollars in parts and prevents a complete breakdown during laundry day.
LG dryers are built with a specific roller and shaft design that gets pretty loud when the lubrication dries out or hair wraps around the axles. You might think it's a major mechanical failure, but honestly it's usually just a worn $30 part that needs about an hour to swap out. These machines can last 15 years if you catch this stuff early.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Component failure in the LG dryer40%
Sensor or thermostat out of operating range24%
Control board fault14%
Power or electrical supply issue12%
Mechanical wear requiring inspection10%
Symptoms You May Notice
A thumping that beats rhythmically once per drum rotation. Gets louder with a full load and almost disappears with an empty drum, which is actually how you know it's the rollers.
High-pitched squealing that starts the moment the dryer kicks on and doesn't stop until you shut it off.
Rattling or clanking that changes tempo as the drum speeds up, like loose change in there but you already checked all the pockets.
The drum catches or drags when you spin it by hand with the door open. Should spin pretty freely if everything's in good shape.
Grinding that starts after about 5 to 10 minutes of running, once the components heat up and expand slightly.
Can you reset a Lg dryer to clear the NOISE code?
While a reset won't fix a mechanical thumping, it can clear the control board if a sensor is tripping. Power the unit down and unplug it for a full minute. While it is unplugged, press and hold the Start/Pause button for five seconds to discharge the capacitors. Plug it back in and see if the noise persists.

Frequently Asked Questions
How much does it cost to fix a LG dryer making noise?
You're typically looking at $150 to $350 for a professional repair. Most of that's labor because LG dryers need significant disassembly to reach the internal parts. DIY is way more affordable. A quality roller kit runs $25 to $50, an idler pulley is $15 to $30, and a belt is another $15 or so. Do all three at once while you're already in there and you're spending maybe $70 in parts total. That's honestly the move if the machine is 5 to 10 years old and you want to be done with it for another 5 years.
Is it worth repairing a LG dryer making noise?
Yeah, almost always. These machines are built to last 10 to 15 years and noise issues are almost always just worn wear parts like rollers, belts, or pulleys. Unless the motor has seized or the drum itself is cracked, spending $50 to $70 on parts beats dropping $900 on a new unit every single time. I rarely tell a customer to scrap an LG just because it's squeaking. If it's under 12 years old, fix it.
Can I fix a LG dryer making noise myself?
If you're comfortable removing a few dozen screws and keeping track of where they go, yes, you can handle this. LG's design is pretty logical once you get the panels off, though you do have to pull the top and front to get inside properly. Take photos before you disconnect the belt so you know exactly how it routes around the drum, idler pulley, and motor pulley. Getting that routing and tension right is honestly the trickiest part of the whole job. Budget about 90 minutes your first time.
What does a failing drum roller actually sound like?
Usually a rhythmic thumping or bumping, kind of like someone slowly knocking on a door. It repeats once per drum rotation, so it's slow when the dryer first starts and picks up pace slightly as the drum gets moving. With a heavy load it's louder, and sometimes with an empty drum it almost disappears completely. That load-dependent quality is pretty much a dead giveaway it's the rollers and not the belt or pulley. If the noise changes based on how much laundry is in there, start with the rollers.
Why does my LG dryer squeal only when it first starts and then stop?
That's classic early-stage idler pulley behavior. When the bearing is just starting to go, it'll squeal when it's cold and then quiet down once the grease inside warms up a bit. Don't be fooled into thinking it fixed itself. It didn't. Within a few weeks or months it'll squeal through the whole cycle, and eventually the pulley seizes completely, the belt snaps, and now you've got a dryer that won't tumble at all. Way easier to fix a squealing pulley than a snapped belt with a seized pulley. Catch it early.
How long do LG dryer rollers usually last?
Honestly, 5 to 8 years with average use. Heavy loads constantly, more like 4 to 6 years. Light use in a single-person household and you might get 10 years out of them. The original factory rollers are decent but nothing special. When you replace them, go with a name-brand compatible roller kit rather than the absolute cheapest option you can find on a random marketplace site. The $8 rollers from unknown sellers tend to wear out fast and you'll be back in there doing it all over again in a year.
