Dryer Taking Too Long to Dry? 8 Causes and What to Check
Most of the time it's airflow: a clogged vent, a crushed hose behind the dryer or a stuck outside flap. Check those first. If strong, warm air comes out of the outside vent and clothes still don't dry, the problem is likely inside the dryer and an appliance technician is the right call.
First: is it the vent or the dryer?
Run the dryer on high for five minutes, then check two things:
| What you find | Likely cause |
|---|---|
| Weak or no air at the outside vent, dryer cabinet hot | Airflow: vent, hose or cap |
| Strong air outside, but it's cool | Heat: a problem inside the dryer |
| Strong, warm air outside, clothes still wet | Load, washer spin, or the dryer's moisture sensor |
The 8 causes, in the order to check
1. A full or clogged lint screen
Empty it every load. Dryer sheets leave an invisible film; if water beads on the screen instead of passing through, wash it with warm soapy water.
2. A clogged dryer vent
The most common cause we find. Lint builds up along the duct and packs at the cap. See the signs of a clogged dryer vent.
3. A crushed transition hose
Pushing the dryer back can flatten the hose behind it and cut the airflow in half. See transition hose replacement.
4. A stuck outside flap
Rust, paint or packed lint can keep the flap from opening. See cap replacement.
5. A vent that's too long
Long runs with many bends slow the air even when they're clean. See the Florida dryer vent code and rerouting.
6. Overloading, or a washer that isn't spinning
Big loads tumble poorly, and clothes that come out of the washer dripping take far longer. If the washer leaves clothes soaked, the washer needs attention.
7. Dirty moisture sensor bars
On sensor-dry cycles, a film on the metal bars inside the drum can end the cycle early. Wipe them with rubbing alcohol, following your dryer's manual.
8. A heating problem
If the air coming out is cool, the dryer isn't heating: on electric dryers often the heating element or a thermal fuse, on gas dryers often the igniter or gas valve. A blown thermal fuse is frequently the result of a clogged vent, so have both checked.
What we check on a visit
We measure the airflow at the outside vent, clean the full line from the dryer to the cap, check the hose and the cap, and measure again. If the vent tests clear and the dryer still doesn't dry, we tell you, so you can call an appliance technician without paying for a vent job you don't need.

Questions
How long should a dryer take to dry a load?
Most loads of towels dry in one normal cycle on high, often under an hour. If it now takes two cycles, something changed.
Why does my dryer get hot but clothes stay wet?
Heat without airflow. The wet air can't get out, which almost always points to the vent, the hose or the outside cap.
Can a clogged vent blow the thermal fuse?
Yes. When the vent is restricted the dryer overheats, and the thermal fuse is designed to blow to stop it. Replacing the fuse without clearing the vent means it will blow again.
Will a new dryer fix slow drying?
Not if the vent is the problem. A new dryer on a clogged vent dries just as slowly.
