Where the moisture goes (drying isn't baking — it's carrying)
A dryer doesn't "bake water away" — hot air moves through the clothes and carries the vapor outside. The workhorse is airflow, not heat. So when clothes won't dry, the heating element is rarely the culprit: the heat is still there, but the carrying route is sealed off by lint — or the supervisor is misreading "done." And that sealing lint is highly flammable — which is why needing two cycles is a warning, not a nuisance.
Match the evidence
- Clothes come out hot but still damp → Heat is fine, check the air path: run the "water-bead test" on the lint screen — if a drop of water beads up instead of soaking through, dryer-sheet softener has left a film. Wash it out with warm soapy water. Then pull the machine out and clear the exhaust duct and exterior vent hood.
- Cycle ends early, clothes never fully dry → Dirty moisture sensor bars: two metal strips near the drum opening, blinded by softener film — the dryer thinks the load is dry and quits early. Wipe them bright with alcohol wipes, then verify with a timed-dry run on a small load.
- A packed-full drum every time, with a permanently damp center clump → Overloading: clothes can't tumble and air can't reach the center. The three-quarters rule plus splitting bulky items saves electricity versus cramming and running twice.
One honest limit: screen clean, duct clear, load reasonable — and clothes still come out hot but damp — the heating element is half-dead (half the heat, innocent airflow). That's 240-volt work; call a tech. A dryer top that's hot to the touch, or a burning smell, isn't a "troubleshooting item" — it's a stop-using-now signal. And never run the dryer with the exhaust duct disconnected — moisture and lint go straight into the room.
