“Air fluff” tumbles the clothes with room-temperature air and no heat. Use it to freshen, loosen or de-dust items, and for things that must not get hot. It does not dry wet clothes quickly, and it is not the same as air drying. If your normal cycles act like air fluff, the dryer has lost its heat.
Key takeaways
- Air fluff tumbles with no heat.
- It freshens and loosens items, but is slow at drying wet ones.
- It is for items that must not get hot, and for refreshing.
- If every cycle feels like air fluff, the heating system has a fault.
What air fluff does
The drum turns and room-temperature air moves through it, with no heat from the element or the burner. That removes dust, loosens fibers and freshens items, and it can finish drying something that is only slightly damp, though slowly. Some dryers name it “air fluff,” “air dry,” “fluff” or “no heat.”
What does air fluff do on a dryer?
It tumbles the clothes with room-temperature air and no heat, for a set time. It freshens, loosens and de-dusts items, and suits things that must not get hot. It is slow at drying wet clothes and is not the same as air drying. Names vary by model, so check your manual.
What to use it for, and what not to
| Good uses | Poor uses |
|---|---|
| Freshening clothes that sat in a closet | Drying a wet load of laundry |
| Loosening and de-dusting pillows and soft items, if the care label allows | Items that need heat to dry, such as towels and jeans |
| Finishing an item that is only slightly damp | Replacing a dryer that has lost its heat |
| Items marked for no heat on the care label: see tumble dry symbols | Anything labeled do not tumble dry |
Is air fluff the same as air drying?
No. Air fluff runs the dryer’s drum with room-temperature air, while air drying means hanging or laying clothes out with no machine at all. Air fluff is faster than air drying but far slower than a heated cycle, and it does not dry a wet load well.
If every cycle feels like air fluff
If your normal cycles tumble with no heat, the clothes come out cold and wet, and the dryer is acting like it is on air fluff, the heating system has a problem. Common causes are a blown thermal fuse, a failed heating element or igniter, or a breaker that is only half on. See dryer not heating, how to test a thermal fuse and how to test a gas dryer igniter.
Why does my dryer run but not heat, like it is on air fluff?
Usually a blown thermal fuse, a failed heating element on an electric dryer, an igniter or valve coil fault on a gas dryer, or one half of the double breaker off. A restricted vent often causes the fuse to blow. Check the breaker and the vent first, then have the heating parts tested.
