Why Is My Dryer Taking So Long to Dry Clothes?
If clothes need two cycles, the vent is the usual suspect — here’s how to tell and what to do.
If your dryer suddenly takes two cycles to dry a normal load, the most common cause is a clogged dryer vent restricting airflow. When lint builds up in the vent line, the hot, moist air cannot escape efficiently, so clothes stay damp and the dryer works harder, runs hotter and takes longer. It is worth addressing quickly — a blocked vent is not just an efficiency problem, it is also a recognized fire risk.
The most common cause: a clogged vent
Every load sheds lint. The lint screen catches some of it, but the rest travels down the vent and collects along the duct and at the bends, slowly narrowing the path for air. The longer or more angled your vent run is, the faster it clogs — which is why the same dryer can dry fine for years and then start struggling.
Other reasons a dryer runs long
- Overloading, so air cannot circulate through the clothes.
- A lint screen that is clogged or coated with fabric-softener film.
- A crushed or kinked flexible vent hose behind the dryer.
- Heavy, over-wet loads that the washer did not spin out well.
- An aging heating element or thermostat — a repair issue, but rule out airflow first.
Quick checks you can do
- Clean the lint screen, and wash it if it has a waxy softener film.
- Feel the exterior vent hood while the dryer runs — weak or no airflow points to a restriction.
- Check that the hose behind the dryer is not crushed.
- Look for lint building up around the outside vent, and notice if the laundry room gets very hot or humid during a cycle.
Warning signs it’s more than efficiency
Some symptoms are safety signals, not just annoyances:
- Clothes are hot at the end of a cycle but still damp.
- A burning smell.
- The top or body of the dryer gets very hot.
- The outside vent flap barely opens, or lint is packed around it.
- You routinely need more than one cycle.
These point to restricted airflow that can cause the dryer to overheat, which is a genuine fire hazard — so slow drying is worth taking seriously.
When to call for professional vent cleaning
If cleaning the lint screen and checking the hose do not fix it, the vent line itself likely needs clearing — especially on long runs or ones you cannot easily reach. A professional clears the full line and confirms the airflow afterward. See our dryer vent cleaning service, and because it is the same kind of airflow issue, you may also want to read about how often air ducts should be cleaned.
Common Questions
Why does my dryer take two cycles now?
Usually lint has built up in the vent and restricted the airflow. A full vent cleaning typically restores normal drying.
Is a clogged dryer vent dangerous?
Yes — restricted airflow makes the dryer overheat and is a known fire risk, which is why slow drying is worth addressing promptly.
I clean the lint screen every time — why is it still slow?
The screen only catches some lint. The rest collects in the vent line beyond it, and that needs to be cleaned separately.
