Direct answer: A Samsung dryer squeaking noise is most often a worn drum support roller, a dry or failing idler pulley, or something rubbing at the front or rear drum support. Start by confirming whether the squeak changes with load size, starts immediately, or shows up only after the dryer warms up.
Most likely: If the squeak is rhythmic and repeats with every drum turn, worn dryer drum support rollers are the first thing I suspect. A sharper constant squeal points more toward the dryer idler pulley or belt path.
Listen for the kind of squeak you have before you open anything up. A once-per-revolution chirp, a steady high-pitched squeal, and a metal rub each send you in a different direction. Reality check: a dryer can keep running for a while with a squeak, but worn support parts usually get worse, not better. Common wrong move: spraying lubricant inside the cabinet without finding the source first.
Don’t start with: Do not start by ordering a control board or guessing at a motor. Noise complaints are usually mechanical, and the sound pattern tells you more than the brand name does.
The sound repeats in a regular rhythm, almost like a chirp each time the drum comes around.
Start here: Start with the drum support path: look for worn dryer drum support rollers, a flat spot, or something rubbing the drum edge.
The noise starts quickly and stays fairly constant instead of pulsing with the drum.
Start here: Check the dryer idler pulley and belt path first. That sound is often a pulley bearing drying out or seizing.
The first few minutes sound normal, then the squeak builds as the dryer runs.
Start here: Lean toward worn support rollers or an idler pulley that gets noisy as heat builds.
An empty drum sounds better, but a normal load brings the squeak back.
Start here: Check for overloading, items caught in the drum seam, and support parts that complain more under weight.
This is the most common cause when the squeak repeats with each drum revolution or gets worse with heavier loads.
Quick check: Run the dryer empty for a minute, then with a few towels. If the sound becomes more rhythmic and louder under load, the rollers move to the top of the list.
A sharp, steady squeal that starts right away often comes from the pulley that keeps tension on the dryer belt.
Quick check: Listen near the lower front or lower side of the cabinet. If the squeal is more constant than rhythmic, suspect the idler pulley.
A belt that is glazed, frayed, or riding out of line can chirp or squeal, especially during startup.
Quick check: Watch for a burning-rubber smell, thumping before the squeak, or a squeak that changes as the drum gets up to speed.
Coins, bra wires, zippers, or a rough drum edge can make a lighter squeak or scrape that sounds like a bad part.
Quick check: Turn the drum by hand with power disconnected and listen for a single rub point or a scratch you can feel at the drum opening.
The sound pattern usually separates a support roller problem from a pulley squeal or a simple rubbing item. That saves a lot of unnecessary teardown.
Next move: If you find and remove a trapped item and the squeak is gone, you likely had a simple drum-path rub and no parts are needed. If the noise remains, use the sound pattern to guide the next checks instead of guessing at parts.
What to conclude: A repeating chirp points toward rotating support parts. A steady squeal points more toward the idler pulley or belt path. A single rub point can still be a foreign object or drum contact issue.
Poor airflow and heavy loads can make a weak support part complain sooner, and sometimes the noise is only showing up because the dryer is running hotter and longer than normal.
Next move: If the squeak drops off with a smaller load or after correcting a badly kinked vent hose, the support parts may still be worn but not yet fully failed. If the same squeak is there with a small load and a clear vent connection, move on to internal mechanical parts.
What to conclude: Load-sensitive noise still usually comes back to rollers or the belt path, but this step helps you avoid blaming the wrong thing for a heat-related complaint.
These two failures sound similar to a lot of homeowners, but they do not usually sound the same in the field. Separating them early keeps you from buying the wrong part.
Next move: If one pulley or roller feels rough, binds, or wobbles, you have a solid repair direction and can stop chasing less likely causes. If the belt path and rollers all look and feel normal, inspect the drum support surfaces and motor area next.
If the rollers and pulley are not the obvious problem, the drum may be rubbing because a support surface is worn or the drum is sitting slightly out of position.
Next move: If you find clear rub marks or a loose, worn support point, correct that mechanical wear before running the dryer again. If there is no visible rub point and the noise source is still unclear, the remaining likely cause is a motor bearing or a less obvious internal support issue.
By this point you should have a real mechanical clue, not just a guess. Most squeaks end with rollers, an idler pulley, or a belt. If none of those check out, the job gets less DIY-friendly.
A good result: If the squeak is gone and the drum turns smoothly, you found the right mechanical fix.
If not: If the squeak is still there after confirmed support-part repairs, stop and have the dryer checked for a motor bearing or deeper internal alignment problem.
What to conclude: A noise that survives good rollers, a good idler pulley, and a good belt is no longer a simple wear-item repair. That is where I stop guessing and start treating it like a motor or structural issue.

Because the usual cause is a worn moving support part, not an electrical failure. The dryer can keep tumbling for a while with a bad roller or idler pulley, but the noise usually gets worse and can lead to belt damage if ignored.
It can be if the squeak comes with a burning smell, heavy scraping, or overheating. A simple chirp from a worn roller is usually not an emergency, but metal rubbing, scorched lint, or a dragging drum means stop using it until it is repaired.
Usually no. Spraying lubricant inside the dryer often attracts lint, contaminates the belt path, and masks the real problem for a short time. If a roller or idler pulley is worn, replacement is the better fix.
A steady high-pitched squeal points more toward the dryer idler pulley. A rhythmic squeak or chirp that repeats with each drum turn points more toward dryer drum support rollers. Hand inspection usually confirms it because the bad part feels rough, loose, or seized.
Only if the dryer drum belt shows wear. If it is frayed, glazed, cracked, or has been rubbing out of line, replace it while the dryer is apart. If the belt still looks healthy and the noise source is clearly a roller or pulley, you do not need to replace parts just because the cabinet is open.
