You throw a load of laundry in the dryer, go do something else, and come back an hour later to find your clothes still damp. You run it again. Still damp. Sound familiar?
A dryer that takes too long is one of the most common appliance problems homeowners deal with. The good news: most causes are easy to understand, and some are even easy to fix yourself.
Here's a simple breakdown of what's likely going on.
The Most Common Reason: A Clogged Lint Trap or Vent
This is the number one cause, and it surprises people every time.
Your dryer needs to push hot, moist air out of the drum and away from your home through a vent. When that vent gets clogged — with lint, debris, or even a bird's nest if the outdoor vent flap isn't covered — the moisture has nowhere to go. The dryer keeps running, but your clothes stay wet.
What to Check
- The lint trap — clean it before every single load. Seriously, every load.
- The vent hose behind the dryer — disconnect it and check for blockages
- The outdoor vent — go outside and make sure the flap opens freely when the dryer is running
Cleaning the full vent system once a year is a good habit. If you have a long vent run (more than 4–5 metres), consider having it professionally cleaned.
It Could Also Be One of These Problems
If the vent is clear and your dryer still runs slowly, here are other possible causes:
- Overloading — a drum packed too full can't tumble properly. Air can't circulate, and drying takes much longer. Try smaller loads.
- Heating element failure — in electric dryers, the heating element can partially fail. The dryer runs and tumbles but doesn't get hot enough to dry efficiently.
- Thermostat issues — the dryer's thermostat controls temperature. A faulty one can cause the dryer to run cool even when it shouldn't.
- Gas supply problems — in gas dryers, weak or inconsistent gas flow can reduce heat output.
- Worn drum seals — the felt seals around the drum keep heat inside. When they wear out, heat escapes and drying becomes slow and inefficient.
When to Call a Professional
Some things you can check yourself — the lint trap, the vent, the load size. But when the issue involves electrical components, heating elements, or gas connections, it's always better to have a certified technician take a look.
Trying to repair these yourself can be dangerous, and it can also void any warranty on the appliance.
If your dryer is taking more than one cycle to dry a normal load, making strange noises, or running hot without actually drying, those are clear signs something mechanical needs attention.
How to Prevent Slow Drying in the Future
A few simple habits go a long way:
- Clean the lint trap before every load
- Don't overload the drum — fill it about 75% full
- Run a spin cycle with no heat first to remove excess water from clothes before drying
- Check the outdoor vent every few months to make sure it's clear
- Have your full vent system cleaned once a year
