Stops almost immediately
The drum starts, maybe turns a few times, then the dryer shuts off within seconds.
Start here: Start with the door latch, door switch signal, load drag, and whether the drum turns freely by hand with power disconnected.
Dryer shutdown problem
Dryer Starts Then Stops
Direct answer: When a dryer starts then stops, the most common causes are restricted airflow causing overheating, a weak door-latch or door-switch signal, or a dryer motor that is overheating and dropping out. Start with the vent path, lint buildup, and door closure before you assume an internal part failed.
Most likely: A partially blocked vent or lint-packed dryer interior is the first thing to rule out, especially if the dryer runs for a few seconds to a few minutes before quitting.
Pay attention to exactly when it stops. A dryer that quits almost immediately points you toward the door switch, start circuit, belt switch on some models, or a dragging drum. A dryer that runs for several minutes and then shuts off usually points toward overheating from poor airflow or a motor that is getting hot and tripping out. Reality check: a lot of these calls end up being a vent problem, not a bad expensive part. Common wrong move: replacing the heating part first because the clothes were still damp.
Don’t start with: Do not start by buying a dryer control board or random gas ignition parts. On this symptom, airflow and heat-safety shutdowns are far more common.

What the shutdown pattern usually tells you
Runs a few minutes, then quits
The dryer starts normally but shuts down after warming up.
Start here: Start with airflow, lint buildup, crushed vent hose, and overheating clues around the lint screen and exhaust.
Only runs while you hold the start button
It starts, but the moment you release the button it stops.
Start here: That points more toward the run circuit, door switch path, or motor switch than a heating problem.
Stops and restarts after cooling down
It quits, then works again later after sitting for a while.
Start here: That pattern strongly suggests a dryer motor overheating from age, lint buildup, or heavy drag.
Most likely causes
1. Restricted dryer airflow causing overheating
A clogged lint path or vent makes heat build up fast. The dryer may run briefly, get too hot, and shut itself down.
Quick check: Run a short timed cycle with the vent disconnected from the back of the dryer if your setup allows safe access. If it stays running and airflow feels much stronger, the vent path is the problem.
2. Loose or failing dryer door switch or latch alignment
If the door signal drops out even for a moment, the dryer stops like you opened the door.
Quick check: Close the door firmly and press on the door near the latch while starting. If the dryer behavior changes, inspect the latch strike and switch area first.
3. Dryer motor overheating and tripping out
A worn motor often starts cold, then quits once it heats up. After cooling, it may run again for a short time.
Quick check: Listen for a low hum, slowing drum, hot electrical smell, or a dryer that restarts only after sitting 20 to 60 minutes.
4. Thermal cutoff or high-limit thermostat trouble after repeated overheating
If the dryer has been running hot for a while, the heat-safety parts may weaken or open. Some dryers will stop heating first; others may shut down during operation depending on design.
Quick check: Look for a history of long dry times, very hot cabinet surfaces, or weak exhaust flow before you blame the safety parts themselves.
Step-by-step fix
Step 1: Pin down exactly when it stops
The timing tells you whether to focus on door/start issues, drag, or overheating. That keeps you from tearing into the wrong area.
- Start the dryer empty on a timed cycle and watch it for the first full minute.
- Note whether it stops in a few seconds, after several minutes, or only after heat builds.
- If it only stops with clothes inside, reduce the load and try again.
- If you have to keep holding the start button to keep it running, note that separately.
Next move: If the dryer runs empty but stops with a normal load, you likely have drum drag, a weak motor, or airflow trouble making the machine work too hard. If it still stops empty, move to the door and airflow checks next.
What to conclude: A seconds-long shutdown usually points to a signal or drive problem. A heat-up shutdown usually points to airflow or a motor that is failing hot.
Stop if:
- You smell burning insulation or see smoke.
- The dryer makes a loud grinding or metal-on-metal sound.
- The plug, cord, or outlet feels hot enough that you do not want to touch it.
Step 2: Check the easy outside causes: door closure, lint screen, and vent hose
These are the most common homeowner-fix causes and they do not require opening the dryer.
- Unplug the dryer.
- Clean the dryer lint filter fully, including any soft film from dryer sheets using warm water, mild soap, and a soft brush if needed. Dry it before reinstalling.
- Open and close the dryer door several times. Make sure it latches cleanly and does not feel loose or springy.
- Inspect the door strike and latch area for cracks, bent plastic, or lint packed into the switch opening.
- Pull the dryer forward and check the vent hose behind it for crushing, kinks, or heavy lint buildup at the connection.
Next move: If the dryer now runs normally, the problem was poor airflow or a weak door closure signal. If nothing changes, test whether the vent path is the main restriction.
What to conclude: A blocked lint screen or crushed vent hose can overheat the dryer fast. A sloppy latch can cut power to the motor circuit mid-run.
Step 3: Separate a house vent problem from a dryer problem
A dryer with the vent disconnected can tell you quickly whether the shutdown is caused by backpressure and trapped heat.
- Keep the dryer unplugged while disconnecting the vent from the back.
- Reconnect power and run the dryer for a short timed test with no clothes, only if the exhaust can blow safely into an open area for a minute or two and you stay with it.
- Feel for strong airflow at the dryer outlet and watch whether it keeps running longer than before.
- If it runs better with the vent off, stop using the dryer normally until the full vent path to the outside is cleaned and checked for a stuck flap, bird nest, or crushed section.
Next move: If the dryer stays on with the vent disconnected, the main problem is the vent path, not an internal dryer part. If it still shuts off the same way with the vent disconnected, move inside the dryer side of the diagnosis.
Step 4: Check for drag and hot-motor clues before replacing parts
A motor that is fighting a hard-to-turn drum or blower can overheat and shut itself off. That can look like an electrical problem when it is really mechanical drag.
- Unplug the dryer again.
- Turn the drum by hand. It should move smoothly with some resistance, not bind, scrape hard, or stop abruptly.
- Listen for rubbing, thumping, or a blower wheel scraping sound.
- Look through accessible openings for heavy lint around the motor area or blower housing if visible without major disassembly.
- If the dryer runs again only after cooling down, note that pattern as a strong motor clue.
Next move: If you find obvious drag or lint-packed airflow parts and correct them, the dryer may return to normal without replacing electrical parts. If the drum turns freely and the dryer still quits hot, the motor or heat-safety components move higher on the list.
Step 5: Act on the most likely internal failure
Once airflow and simple external causes are ruled out, the remaining likely fixes are more specific and worth diagnosing before you buy anything.
- If the dryer stops when the door is jostled or the latch feels weak, inspect and replace the dryer door switch or damaged latch parts as needed.
- If the dryer runs, gets hot, quits, then restarts only after cooling, plan on a dryer motor diagnosis and likely replacement.
- If the dryer has a history of overheating, long dry times, and poor airflow, inspect the dryer thermal cutoff and dryer high-limit thermostat only after the vent problem is corrected.
- If the dryer only runs while the start button is held, treat that as a motor switch or start-circuit clue rather than a heating-part problem.
- If you are not equipped to open the cabinet and test continuity safely with power disconnected, book service and give the tech the exact shutdown pattern you observed.
A good result: Replacing the right confirmed part after the airflow issue is fixed should restore normal run time and prevent repeat shutdowns.
If not: If the symptom remains after vent correction and the obvious switch or motor clues do not line up cleanly, professional diagnosis is the smart next move because control and wiring faults are less common but possible.
What to conclude: At this point you should have a clear direction: door-switch path, motor-overheating path, or heat-safety path after an overheating history.

FAQ
Why does my dryer start and then stop after a few seconds?
That usually points to a door-switch problem, a weak latch, a start-circuit issue, or a motor that cannot stay in the run mode. It can also happen if the drum is dragging badly and the motor overload trips almost right away.
Why does my dryer run for a few minutes and then shut off?
That pattern is most often overheating. Start with the lint filter, vent hose, and full vent path to the outside. If airflow is good and it still quits hot, a failing dryer motor becomes much more likely.
Can a clogged vent make a dryer shut off completely?
Yes. Poor airflow traps heat inside the dryer. Some machines will stop heating first, while others will shut down during the cycle as temperatures climb. Long dry times and a very hot cabinet are common clues.
If my dryer restarts after cooling down, is the motor bad?
Very often, yes. A dryer motor that runs again after sitting is a classic overheating-motor symptom. Still check for drum drag and lint-packed airflow parts first, because those can overwork an otherwise usable motor.
Should I replace the thermal cutoff right away?
Only if testing shows it failed. And if it did fail, correct the airflow problem first. A thermal cutoff usually opens because the dryer got too hot, so replacing it without fixing the overheating cause often leads to another failure.
Why does my dryer only run while I hold the start button?
That usually points away from the heating system and more toward the motor run circuit, door-switch path, or a related internal switch issue. It is a useful clue because it narrows the problem to how the motor stays energized after startup.
