The most frequent cause is restricted airflow, from a full lint filter or a clogged vent, not a broken dryer. Fix the airflow first, because a clogged vent also overheats the machine.
Check in This Order
- Empty the lint filter each load, and scrub it with soap occasionally, since fabric softener leaves a film that restricts air.
- Slide the dryer out and inspect the vent hose. Crushed or kinked hoses hold back air.
- Check the outside vent flap while the dryer is operating. It should open wide.
- Do not overload the drum. Clothes need room to tumble.
If the Airflow Is Good
A drum that turns without heat points to a heating part, a thermostat or a control problem. Heat that comes and goes may be a sensor. Damp clothes with plenty of heat suggest moisture sensing is off. We cannot tell these apart without testing, and the parts differ for each.
Houston Factors
Long vent pipes through attics trap lint and summer heat, and humid air makes drying slower in any machine. If your dryer vents a long way, the vent often needs cleaning before anything is replaced.
On an older dryer we say honestly whether the repair is worth it, and the price is given to you in writing before the work starts. See our ASKO dryer repair page.
Here is a quick test: while the dryer is operating, hold your hand at the outside vent. Strong, warm airflow means the vent is probably clear. Weak or no airflow means the vent is clogged, and that should be cleared before any part is replaced. The result also tells us where to start when we come.
