Why Is My Dryer Taking Too Long to Dry?

When a dryer that used to finish a load in one cycle suddenly needs two or three, the most common culprit isn't a major mechanical failure — it's airflow.

A clogged lint trap or vent. Restricted airflow is by far the most common reason dryers take longer to dry, since the moist air has nowhere to escape efficiently.

An overloaded drum. Too many clothes at once restricts both tumbling and airflow, so the dryer has to work much harder to dry everything evenly.

A partially failed heating element. An element that's still working but not at full strength will dry clothes more slowly rather than not at all.

A failing moisture sensor. On sensor-dry cycles, a miscalibrated sensor can cause the dryer to run inefficiently or end cycles before clothes are actually dry.

Cleaning the lint trap before every load and checking the exterior vent flap are the easiest first steps — if long dry times continue after that, the vent line itself may need a deeper cleaning, or a component may need repair.
