If a normal load now needs a second cycle, the dryer usually isn't moving heat and moisture out of the drum. The U.S. Consumer Product Safety Commission says clothes that stay damp, or that take longer than a typical cycle, can mean the lint screen or the exhaust duct is blocked.
That's where we start. But it's not the whole story. We've pulled crushed foil hose out from behind a machine that still "looked fine." We've opened a stuck outdoor flap, and we've found lint packed at an elbow on a roof or attic run. Once in a while it's an appliance problem that cleaning won't fix. Don't just wipe the short connector behind the dryer. You want the full exhaust path checked.
Why does a second drying cycle happen?
Short answer: A dryer dries clothes by pushing hot, moist air through the vent and out of the house. When that path is restricted, moisture stays in the drum and the load finishes wet.
The lint screen catches a lot of lint. It doesn't catch all of it. Fiber still travels into the exhaust line and packs at elbows, crushed sections, and the outdoor hood. Heat still builds in the cabinet. Moisture has nowhere to go. Cycle ends. Towels still damp. Sound familiar?
Running it again adds time and heat. It doesn't open the restriction.
CPSC Publication 5022 is plain about this: fires can occur when lint builds up in the dryer or in the exhaust duct, because lint can block airflow and cause excessive heat. Longer drying times are listed there as a warning sign. Not a minor inconvenience.
Is a clogged vent the only reason clothes stay damp?
Short answer: No. One symptom doesn't prove a blockage.
Before anyone opens a wall or climbs a roof, rule out the simple stuff:
- The lint screen is packed, wet, or filmed over with fabric-softener residue.
- The load is larger or wetter than the dryer can handle in one cycle.
- The short hose behind the dryer is crushed, kinked, or pulled off the wall collar.
- The outdoor flap is stuck shut.
Common. And easy to miss if you only look at the appliance settings. If the screen is clean, the hose is open, and a normal load still needs two cycles, the restriction is often farther down the line. Or the dryer itself has a heating, thermostat, or blower problem. Cleaning should find why airflow is restricted. And we say so when cleaning alone won't correct it.
What are the signs of a clogged dryer vent?
Short answer: Longer drying times are the one most people notice first. Heat, smell, lint, and weak outdoor airflow usually show up with it.
If you're seeing one of these, have the path inspected. Same signs already listed on our dryer vent cleaning page and in the FAQs.
| What you notice | What it often points to | What to do |
|---|---|---|
| Clothes still damp after a normal cycle | Heat and moisture are not leaving the drum | Clean the lint screen. Check the outdoor hood. Then inspect the full path. |
| Laundry room or dryer cabinet unusually hot | Exhaust is backing into the room | Stop stacking cycles. Inspect the line and the termination. |
| Burning smell while the dryer runs | Lint, a crushed hose, or an appliance fault | Stop the dryer. Don't keep running it to "finish the load." |
| Visible lint behind the dryer or at the outdoor hood | Lint is escaping the screen and collecting in the path | Cleaning behind the dryer is not the same as cleaning the vent. |
| Weak or no air at the exterior vent | Restriction in the line or a flap that will not open | That's a reason to inspect the full exhaust path. |
| Vent has not been cleaned in a long time, or it is a long / roof run | Lint has had time and distance to collect | Schedule a full-path inspection, not a hose wipe. |
A burning smell is a stop-the-dryer sign. Not a "run one more cycle" sign. Lint can be the cause. A failing motor, belt, or electrical part can be the cause too. Don't treat every odor as a simple cleaning job.
How can I check airflow at the exterior vent?
Short answer: Run the dryer and check whether air is actually leaving the house.
CPSC tells homeowners to check the outside dryer vent while the dryer is operating and to make sure the outdoor flap will open. NFPA gives the same check: confirm the exhaust pipe is not restricted and the outdoor flap opens, then clean lint out of the vent pipe.
Here's the check, if you can reach the hood from the ground:
- Clean the lint screen.
- Start a cycle with a normal load.
- Go to the outdoor hood—if you can reach it safely from the ground.
- Confirm the flap opens and you can feel steady exhaust.
If the flap stays shut, or the air is weak, the path is restricted somewhere between the dryer and the hood. Could be the short hose. Could be a mid-run elbow packed with lint. Could be the hood itself, painted shut or packed from the inside.
And a lot of Central Florida homes and condos terminate through an attic or the roof. If you can't see the termination from the ground, don't get on the roof to force a check. Tell us where the dryer sits and, if you know, where the vent exits. That's enough to plan the inspection.
Is cleaning behind the dryer the same as cleaning the vent?
Short answer: No.
The short connection behind the dryer is one piece of the exhaust path. That's it. A complete service takes the line to the exterior termination and checks what we can reach at both ends. Our FAQs already say this. People still miss it. They vacuum the hose, slide the dryer back, and need two cycles the next week.
Flexible plastic or foil accordion duct is a frequent find in that short run. CPSC recommends replacing that material with rigid or corrugated semi-rigid metal duct because plastic and foil trap lint more easily and crush or kink. If we find a damaged, crushed, or non-metal connector, we photograph it and walk you through what cleaning can and can't fix. We don't treat a hose wipe as a completed vent cleaning.
How often should dryer vents be cleaned?
Short answer: Clean the lint screen before or after every load. Clean lint out of the vent pipe at least once a year. Some systems need it sooner.
That yearly vent-pipe interval isn't a marketing line. CPSC's March 2023 safety release says to clean lint out of the vent pipe at least once a year. NFPA's dryer-safety guidance says the same: clean lint out of the vent pipe once a year. NADCA, the air-duct and dryer-vent trade association, recommends a professional dryer-vent cleaning once a year and is clear that emptying the lint trap isn't enough.
Annual is a baseline. Not a rule that every house can wait twelve months. In the field, we see faster buildup when:
- The dryer runs most days.
- The vent is long, has several elbows, or exits through the roof.
- The connector behind the dryer is foil, plastic, or crushed.
- Pets, towels, and rugs put more lint into the line.
- The outdoor hood sits in weather, insects, or debris—common on Brevard exterior walls.
But if drying time is already stretching into a second cycle, don't wait for the calendar. The system is telling you the path is restricted now.
What does a complete dryer vent cleaning include?
Short answer: Inspect the accessible path, clean the full exhaust line, check the termination, and leave a record of what changed.
That's the work on our residential dryer vent cleaning page:
- A visual review of the accessible dryer connection and vent path
- We use a brush and a vacuum on the line
- A check of the accessible exterior termination or roof vent
- Airflow observations before and after service when they apply
- Photos and clear findings
- Recommendations when we find a damaged hose, a blocked termination, or another condition cleaning will not correct
Roof and attic runs are a little different from a short wall termination. Access, length, height, and weather all change the job. We confirm the approach before work begins.
A short note for property managers
The same two-cycle complaint shows up unit by unit in apartments, condos, and HOA buildings. Shared walls, roof stacks, and occupied units change access and reporting. We scope that work separately—unit count, termination type, and a completion record that shows which units were done and which we couldn't reach. Start on the commercial and multifamily page if that's the situation.
When should I stop using the dryer and call?
Short answer: Stop stacking cycles when the clothes stay wet, the room gets hot, you smell burning, or the outdoor vent isn't moving air.
Keep using a restricted dryer and you add heat to a line that may already hold lint. NFPA's 2017 analysis of 2010–2014 home fires found that failure to clean was the leading factor in one-third (33%) of clothes-dryer fires, and that dust, fiber, or lint was the leading item first ignited in those dryer fires (27%). Those figures are historical. They're still the reason we treat a two-cycle dryer as a vent problem first, not as a "buy more time on the knob" problem.
Call if any of these are true:
- A normal load now takes two cycles.
- The laundry room is hotter than it used to be.
- You notice a burning smell or a lot of lint around the machine.
- The outdoor hood is weak, stuck, or packed.
- You don't know when the full vent was last cleaned.

Frequently asked questions
Why is my dryer taking two cycles to dry?
Because heat and moisture aren't leaving the drum the way they should. CPSC lists damp clothes and longer-than-normal drying times as a sign the lint screen or exhaust duct may be blocked. Confirm the screen is clean, then check outdoor airflow and the full vent path.
What are the signs of a clogged dryer vent?
Longer drying times, a hot dryer or laundry room, a burning smell, visible lint, and weak airflow at the exterior vent. A stuck outdoor flap or a vent that hasn't been cleaned in a long time belongs on the same list. One sign is enough to inspect. It isn't enough to assume the only problem is lint.
How often should dryer vents be cleaned?
Clean the lint screen with every load. CPSC and NFPA both say to clean lint out of the vent pipe at least once a year. NADCA recommends a professional cleaning once a year. Long runs, roof terminations, crushed connectors, and heavy use often need attention sooner—especially once drying time has already stretched.
