A dryer shaking has no balance system behind it, because a dryer does not have one. No suspension, no counterweight, no spin-balance routine refusing to proceed — just a drum turning at walking pace on rollers, a blower wheel beside it, four adjustable feet underneath. The washer explanation everyone reaches for does not apply. The shortlist is the feet, the load, and three rotating parts that no longer turn smoothly.
A dryer shaking has no balance system to blame
A washer spins a wet load at over a thousand revolutions a minute, which is why it has suspension and why it aborts a cycle rather than accelerate a load it cannot balance. A dryer drum turns slowly, and nothing in it reacts to vibration — so nothing pauses, nothing throws a code, and the cabinet passes whatever is happening mechanically straight into the floor undampened. The shaking is a direct report of a condition, not a control system expressing an opinion.
GE Appliances publishes the normal-versus-not list for dryer sound, and vibration sits in the second column. Not normal: “A thumping sound. A humming sound” (GE Appliances).
Level is not the same as stable, and the feet decide which
This is the part most pages get wrong. Levelling a dryer is not about getting a bubble between two lines — it is about getting all four feet properly loaded, and those are different jobs.
Samsung states the thing nobody else does: “When leveling the dryer, the leveling feet should only extend the minimum amount necessary. If the legs are too long, the dryer may still vibrate, even if the top is level” (Samsung). An extended foot is a lever, so a cabinet on four long screws can be level and still free to rock. The procedure therefore runs backwards: “Retract the leveling feet completely, and then use a carpenter’s level to check which feet need adjusting.”
GE adds the clause that earns its place: “nothing is leaning against the Dryer.” A broom resting on a running cabinet knocks exactly like a failing part. None of this reaches a dryer that is not on the floor at all: stacked above a washer its feet carry nothing, and the brackets of a washer dryer stacking kit are what hold it steady instead, so a missing or loose kit shows up as shaking no amount of levelling will settle.
Four parts that make a running dryer move
Three rotate and one holds the machine up. Each gives the shaking its own rhythm, which separates them without opening anything.
- Drum support rollers. A slow thump, once per drum revolution. Whirlpool documents a benign version with an expiry date: on a dryer left unused, “the drum support rollers may flatten where they touch the drum when not in use. As the dryer runs, the rollers should regain their shape” (Whirlpool). Still thumping after several cycles and that excuse has run out.
- The idler pulley. From the front, worse once warm. Whirlpool: “a worn-out idler pulley.”
- The blower wheel. A fast buzzing rumble felt in the floor, because it turns far quicker than the drum. Whirlpool: a rumble “can result from the blower wheel being loose, off-balance, or obstructed by lint or debris.”
- Loose cabinet screws. Free to fix. GE: “Check all exposed screws and make sure they are tight.”
A drum that has stopped turning while the motor runs is past shaking (dryer not spinning).
Run it empty and the load stops being a suspect
Two minutes, no tools. Empty the drum, shut the door, start a timed cycle with no heat, and stand there. A smooth empty drum means the load was doing it — trainers, a rolled duvet that never unrolls, one heavy wet towel with nothing to tumble against. One that still shakes has only itself to blame, and the rhythm above says which part.
Then pull the lint screen and look down the chute with a torch. Maytag notes items “can occasionally fall into the chute and hit the blower wheel, causing a rattling or knocking sound.” A coin against a blower wheel is not a repair. It is a coin.
FAQ
Is some dryer vibration normal?
The sound of the drum turning is normal. GE lists a thumping sound and a humming sound as not normal, so anything you feel through the floor from across the room has crossed that line.
Can an unbalanced load make a dryer shake?
Yes, and rule it out first. Heavy single items and solid objects such as trainers thump because nothing cushions them. Unlike a washer, a dryer will not refuse the load.
How do I stop my dryer from shaking?
Retract all four feet, level the cabinet with them wound in, then extend each only as far as the floor requires. Check nothing leans on it and the exposed screws are tight.
Can a shaking dryer damage itself?
Yes. GE advises you “discontinue use of the Dryer until it has been checked by a qualified servicer. Continued use may cause wear of other parts, making the repair more costly” (dryer making loud noise).
Retract the feet, then listen to an empty drum
Wind all four feet in, level it with them retracted, bring each up only as far as it needs, then run it empty for two minutes.
A quiet empty dryer means a loading habit, not a repair. One that still shakes, count the beats: slow and once per turn is rollers, front and warm is the idler, fast and in the floor is the blower.
