Dryer Stops Mid-Cycle: Causes and What to Check
You start the dryer and walk away. Later you find it stopped, and the clothes are still damp. A dryer that stops mid-cycle is annoying, but the cause is often simple. This guide lists the most common causes, in the order to check them.
Safety first. Unplug the dryer before you look inside it. For a gas dryer, shut off the gas valve too. If you smell gas, leave the house and call the gas company.
Common causes
- A blocked vent or full lint filter. Hot air cannot escape, the dryer overheats, and a safety part switches it off.
- An overloaded drum. Too many clothes strain the motor and block airflow.
- A worn door switch. If the switch loses contact when the drum turns, the dryer stops.
- A failing thermal fuse or thermostat. These parts are meant to cut power when the dryer gets too hot, but a faulty one can cut it too early.
- A tired motor, belt or idler pulley. The motor may overheat and shut down, then start again after it cools.
- A power problem. An electric dryer needs both legs of its 240V supply. If one is lost, the dryer may start and then stop.
What to check in about ten minutes
- Clean the lint filter and wash it with soap and water if it looks coated.
- Pull the dryer forward a little and look at the vent hose. It should not be crushed or kinked.
- Go outside and check the vent flap while the dryer runs. It should open and push out warm air.
- Run a half load. If it finishes, the full load was too much for it.
- Open and close the door a few times. The door should click firmly. A loose or noisy latch points to the switch.
- Check the breaker panel. An electric dryer uses a double breaker.
When to call a technician
Call if the dryer keeps stopping after the vent is clear, if you smell burning, or if the breaker trips. Do not keep restarting a dryer that shuts off from heat. The safety part is doing its job, and something is wrong. Our warning signs guide lists what to watch for.

Why a clean vent matters so much
When the vent is blocked, hot air stays in the drum. The dryer gets hotter than it should, and its safety parts switch it off to protect it. This is why a dryer can run fine for 20 minutes and then stop. Cleaning the lint filter and the vent often fixes the problem. It is also the cheapest thing to try first.
What a technician checks
- The vent and the airflow, from the dryer to the outside flap.
- The thermal fuse and the high-limit thermostat, which cut power when heat is too high.
- The door switch and latch, for loose or worn contacts.
- The drive motor, belt and idler pulley, for strain or a motor that overheats.
- The power supply, to make sure both legs of an electric dryer are working.
How to stop it from happening again
- Clean the lint filter before every load.
- Do not overload the drum. Clothes need room to tumble.
- Have the vent cleaned when drying times get longer.
- Keep the area behind the dryer clear so the hose is not crushed.
Common questions
Why does my dryer stop and then start again after a few minutes?
This often means a safety part has switched it off because of heat, and then reset when it cooled. A blocked vent is the most common cause. Do not ignore it, because the heat is the warning.
Is it safe to keep running a dryer that shuts off?
It is better to stop and find the cause. A dryer that overheats can be a fire risk, and the safety part may fail if it keeps being tested.
Why does it stop at the same point in every cycle?
A fixed point often points to a door switch, a drum that rubs, or a part that warms up and then fails. A technician can test these.
Can overloading make a dryer stop?
Yes. A heavy load strains the motor and blocks airflow, so the dryer can overheat or stop.
