Direct answer: A dryer that rattles is usually dealing with something loose or worn, not a heating problem. Start by checking for hard items in the drum, a loose lint screen or exhaust connection, and a dryer cabinet that rocks on the floor before you suspect internal parts.
Most likely: The most common causes are coins or fasteners in the drum baffles, a loose lint filter housing area, a shaky dryer leg, or worn drum support parts that let the drum chatter as it turns.
Listen to when the noise happens. A light metallic rattle right away often points to something loose in the drum or cabinet. A deeper rattle that gets louder as the drum turns leans more toward worn drum support hardware. Reality check: one coin can make a dryer sound much worse than the actual repair. Common wrong move: running more loads and hoping the noise 'works itself out' while a loose part keeps chewing up the drum or front seal.
Don’t start with: Don't start by ordering a motor or control part. Rattling is usually a simple loose-item or support problem first.
Sounds like a coin, zipper, button, or screw bouncing around, especially with lighter loads.
Start here: Empty the dryer, spin the drum by hand, and inspect the drum baffles, lint screen opening, and front lip of the drum for trapped items.
The whole dryer buzzes or chatters against the floor or wall, and the sound changes if you press on a corner.
Start here: Pull the dryer slightly away from the wall, check the leveling feet, and make sure the exhaust connection is not tapping the back panel.
The dryer starts, then a repeating rattle follows the drum rotation and may get worse with heavier loads.
Start here: Suspect worn drum support parts such as dryer drum rollers or a dryer idler pulley after the simple loose-item checks are done.
The noise seems lower in the cabinet and may come with weak airflow or extra lint around the machine.
Start here: Check the lint screen fit, lint housing area, and blower area for debris or a loose blower wheel before assuming a major failure.
Coins, bra wires, screws, and zipper pulls make a sharp rattling sound and are far more common than failed major components.
Quick check: Run the dryer empty for a minute. If the rattle changes or disappears, inspect the drum, baffles, and lint screen opening for trapped items.
A dryer that rocks even a little can rattle against the floor, wall, or exhaust connection, especially at startup.
Quick check: With the dryer off, push on each top corner. If it wobbles, adjust the feet and make sure the vent is not pressing on the back panel.
A loose blower wheel or debris that made it past the lint screen can create a lower, faster rattle from the front or lower cabinet.
Quick check: If the noise seems strongest near the lint screen or lower front and airflow is weaker than normal, inspect that area next.
Flat-spotted dryer drum rollers or a worn dryer idler pulley let the drum and belt run rough, which often sounds like a repeating rattle or chatter.
Quick check: Turn the drum by hand with power disconnected. Rough spots, scraping, or side play point toward internal support wear.
This is the safest and most common fix, and it costs nothing to check before opening the cabinet.
Next move: If the rattle is gone after removing debris, you found the problem. Keep using the dryer, but watch the next load to make sure nothing else is trapped. If the dryer still rattles empty, move on to the cabinet and vent check.
What to conclude: A noise that stays with an empty drum usually comes from the cabinet, blower area, or drum support parts rather than from clothing hardware.
A shaky cabinet can sound like an internal failure when the real problem is just poor footing or a vent pushing on the back panel.
Next move: If the rattle changes or disappears after leveling or moving the vent, the cabinet was transmitting the noise. If the sound is still there and seems to come from the front, lower cabinet, or drum rotation, keep going.
What to conclude: A dryer that rattles no matter how solidly it sits is more likely dealing with debris in the blower area or worn internal support parts.
These two problems can sound similar, but the clues are different enough that you can avoid buying the wrong part.
Next move: If you find and remove debris or tighten a loose panel or housing screw, retest with a small load. If the noise clearly follows drum rotation or the drum feels rough by hand, plan on opening the cabinet to inspect support parts.
Once the easy checks are done, these are the most common internal causes of a true repeating dryer rattle.
Next move: If you find worn rollers or a loose idler, replace the failed support parts as a set where practical, then reassemble and test. If the rollers and idler look solid, inspect the blower wheel next before going deeper.
A loose or damaged blower wheel can rattle hard, but by this point you should have ruled out the simpler causes first.
A good result: If the dryer runs smoothly through an empty test and a small load, the repair path was correct.
If not: If the noise is still strong after these checks, stop throwing parts at it and get a pro to inspect the motor mount, drum supports, and cabinet structure.
What to conclude: A persistent rattle after the common fixes usually means a less obvious internal failure or multiple worn parts at once.

That usually points to loose items in pockets, hardware on the clothes, or drum support parts that only complain once the drum is carrying weight. Test it empty first, then with a small load to separate those two.
Yes. A single coin or screw can make a loud metallic rattle as it hits the drum baffles or slips near the lint housing. It is one of the most common causes.
Only if you have confirmed it is something minor like a loose item or a cabinet that needed leveling. If the noise is getting louder, follows drum rotation, or comes with burning smell or weak airflow, stop using it until you inspect it.
Dryer drum rollers are a top suspect when the noise repeats with each turn of the drum. A worn dryer idler pulley is another common one, especially if the sound is more of a chatter from the belt path area.
Yes, but usually from the vent connection tapping the dryer cabinet or from vibration caused by a dryer that is pushed too tightly against the wall. A blocked vent is more likely to cause long dry times, heat buildup, or a burning-lint smell than a true internal rattle.
That often points toward the blower area or lint housing rather than the drum itself. Look for debris, a loose panel, or a damaged dryer blower wheel, especially if airflow also seems weak.
