Laundry should be fast and simple. If your dryer takes too long to dry clothes, the problem wastes time, energy, and money. Long cycles can also overheat parts and shorten the life of the machine. You can often fix the cause with a few basic checks. This guide will help you find what’s slowing things down so your dryer works like it should.
What Causes a Dryer to Run Too Long?
Dryers need strong airflow to move hot air through the machine. When airflow is blocked, the heat can shut off early, leaving your clothes damp. This is one of the most common causes of long drying times.
Here are a few spots to check:
- The vent hose connected to the back of the dryer
- The wall duct that leads to the outside
- The outside vent cap or screen
If lint or dust clogs any part of the system, air can back up. This prevents the heat from staying on and causes the dryer to run much longer than it should.
Key Takeaway: A blocked vent can keep your dryer from heating properly. Always make sure the air has a clear path out of the machine.
Dryer Takes Too Long to Dry Clothes? Check the Washer Too
Sometimes, the dryer is working fine, but the washer is not. A common problem is a leaking water valve inside the washer. After the spin cycle finishes, water may keep dripping in, soaking the clothes again.
When that happens, the dryer has to remove more water than normal. This makes the cycle take much longer.
Pro Tip: After the washer finishes spinning, check how wet the clothes feel. If they are wetter than usual, the washer could be the source of the problem.
Make Sure the Dryer Heat Stays On
Dryers are designed to heat only when certain conditions are met. Most use an airflow switch that completes the heating circuit. If airflow drops, that switch can shut off the heat.
Ask yourself:
- Does the dryer feel hot the whole time it runs?
- Are the clothes warm but still wet at the end?
If the heat turns off early or never comes on, airflow or a faulty switch could be to blame.

Moisture Sensors and Load Type Settings Matter
Modern dryers have moisture sensors. These sensors check how wet your clothes are. Then, they adjust the drying time to match. These sensors are smart, but they work best when you choose the correct load type.
For example:
- Thick cotton towels take longer to dry than lightweight sheets
- Polyester blends need less heat than 100% cotton
- Large, heavy loads take more time than smaller ones
If you choose the right cycle, the dryer uses the right heat. It also checks the moisture level as the clothes dry.
Key Takeaway: Use the correct setting based on what you’re drying. Let the dryer’s technology do its job by giving it the right input.
