Direct answer: An LG dryer squeaking noise is most often a worn drum support roller or idler pulley, especially when the squeak starts as the drum begins turning and gets louder as the dryer warms up.
Most likely: Start by figuring out whether the squeak is coming from inside the cabinet or from the vent area behind the dryer. If the sound is clearly inside the dryer and happens every rotation, worn drum support parts are the leading suspects.
A sharp squeak, chirp, or rubbery squeal usually means something that supports or drives the drum is dry, worn, or dragging. Reality check: dryers often squeak for a while before they quit, but that noise is usually a warning, not a harmless quirk. Common wrong move: spraying lubricant into the dryer without opening it up first. That can sling oil onto the belt, drum, or lint and make the repair messier.
Don’t start with: Don't start by buying a heating part or control board. Those don't match a simple squeak complaint, and they waste money fast.
The sound repeats in a steady rhythm as the drum turns, almost like one bad spot comes around each rotation.
Start here: Start with the drum support roller and dryer belt path. A repeating rhythm usually points to a moving drum support part, not the motor.
The dryer starts tumbling, then makes a constant squeal that may ease up after a minute.
Start here: Check the idler pulley and dryer belt area first. That startup squeal is a classic belt-tension support noise.
The noise is louder behind the dryer, near the wall, or at the outside vent hood.
Start here: Check the vent hose, wall connection, and outside flap before opening the dryer. A loose or rubbing vent can sound a lot like an internal squeak.
The dryer squeaks, struggles to turn, or leaves a hot rubber smell during the cycle.
Start here: Stop using it and inspect for a dragging dryer belt, seized roller, or stuck idler pulley. That combination can turn into a belt failure fast.
This is the most common source of a repeating squeak or chirp on a tumbling dryer. The roller bushing dries out or the wheel develops a flat spot, so the drum squeaks once each turn or gets noisy as it warms up.
Quick check: Run the dryer empty for a minute. If the squeak stays on the same rhythm with no clothes inside, suspect a drum support roller.
A constant startup squeal or sharp chirp that changes as the belt tightens often comes from the idler pulley. It sits in the belt path and makes noise when its bearing wears.
Quick check: Listen during the first 10 to 20 seconds after pressing start. If the squeal is strongest right away and follows belt tension, the idler pulley moves up the list.
A belt can squeak when it gets polished, frayed, or starts dragging on a misaligned pulley or stuck roller. You may also notice weak tumbling or a rubber smell.
Quick check: If the dryer squeaks under a normal load but sounds better empty, inspect the belt path after ruling out an overloaded drum and vent restriction.
A loose foil-style vent, kinked hose, or vibrating wall connection can make a squeak or chirp that sounds internal from the laundry room.
Quick check: Pull the dryer forward slightly and listen at the back while it runs. If the sound changes when you steady the vent hose by hand, start there.
You want to separate an internal drum-support noise from a vent or installation noise before taking the dryer apart.
Next move: If the noise changes or disappears when the vent hose is steadied or repositioned, fix the vent routing and test again before opening the dryer. If the squeak is still clearly coming from inside the dryer, the problem is likely in the drum support or belt path.
What to conclude: A noise outside the cabinet points to vent rubbing or vibration. A steady internal squeak points to rollers, the idler pulley, or the dryer belt.
An overloaded drum or restricted airflow can make normal support wear sound much worse and can also overheat the belt path.
Next move: If the squeak is gone after correcting the load or vent routing, keep using the dryer but watch for the noise returning. Support parts may still be wearing. If the squeak remains empty and loaded, especially with a steady rhythm, internal wear is more likely than a simple airflow issue.
What to conclude: Load-sensitive noise can still involve worn support parts, but this step keeps you from blaming the dryer when the vent or load is the real trigger.
These three parts cause most squeaks that come from inside a dryer cabinet, and the sound pattern usually tells you which one is leading.
Next move: If you find one rough or seized support part, you have a solid repair direction. Replace the failed part and inspect the rest of the belt path before reassembly. If all support parts spin smoothly and the belt looks good, the noise may be coming from a motor bearing or another internal issue that is less DIY-friendly.
Once the noisy part is identified, a focused repair is cheaper and more reliable than guessing. This is where parts actually make sense.
Next move: If the dryer runs quietly through startup and a full warm cycle, the repair was on target. If the squeak is still there after replacing the confirmed worn support part, stop before buying more parts blindly and consider a motor-bearing diagnosis or professional service.
A quick empty test is not enough. You want to know whether the squeak is truly gone under heat and load, or whether a deeper problem is still there.
A good result: If the dryer stays quiet through a full small-load cycle, you can return it to normal use.
If not: If the squeak persists after the obvious support parts check out, the next move is professional diagnosis rather than more guess-and-buy parts.
What to conclude: A quiet startup and quiet loaded cycle confirm the repair. A persistent squeak after good rollers, pulley, and belt points away from the common DIY fixes.

That usually points to the dryer idler pulley or another belt-path support part starting dry and noisy under initial tension. If the squeal fades after a minute, the idler pulley moves high on the list.
Maybe for a very short time, but it is not a good bet. A squeak often means a roller, pulley, or belt is wearing out. If you also smell rubber, hear grinding, or the drum struggles, stop using it.
Not usually. Most squeaks come from the dryer drum support rollers, idler pulley, or belt. A motor issue is more likely after those parts check out and the noise still stays inside the cabinet.
No. On most dryers that is a temporary mess, not a real repair. Oil can spread onto the belt and lint. If a roller or idler pulley is rough enough to squeak, replacement is the better fix.
Heat can make a worn roller bushing, idler pulley bearing, or glazed belt complain more loudly. It can also make a restricted vent raise cabinet heat, which makes an already worn support part noisier.
