Runs a few minutes, then shuts off
The drum turns normally at first, then the dryer gets very warm and quits before the load is dry.

Dryer Troubleshooting
Dryer Won't Stay Running
Direct answer: When a dryer won't stay running, the most common cause is restricted airflow making it overheat and trip a safety thermostat. If it shuts off almost immediately, look harder at the door switch, broken belt path, or a failing drive motor.
Most likely: Start with the lint screen, blower area, and exhaust vent. A dryer that runs a few minutes, gets hot, then quits is usually telling you it cannot move air.
Watch exactly when it stops. A dryer that dies after several minutes is a different problem than one that clicks off as soon as you let go of the start button. Reality check: many "bad dryer" calls end up being a packed vent. Common wrong move: replacing heating parts before checking airflow, then cooking the new parts the same way.
Don’t start with: Don't start by ordering a dryer control board or random thermostat kit. The shutdown pattern matters, and airflow problems are more common than failed electronics.
Stops after a few minutesCheck lint buildup and the full vent path first.
Stops almost right awayFocus on the door switch, belt break path, and motor behavior.

What the shutdown looks like
Stops as soon as you release the start button
It will run only while you hold the start button, or it clicks and dies right away.
Start here: Check the door latch feel, door switch response, and broken-belt path.
Shuts off with a hot or burnt smell
The cabinet feels unusually hot, clothes are extra hot, or you smell hot lint.
Start here: Stop using it and inspect the lint path and vent before another test.
Starts, hums, or struggles, then quits
You hear a hum, a strained start, or a short run followed by shutdown.
Start here: Look for a tight drum, seized support parts, or a failing dryer drive motor.
Most likely causes
1. Restricted dryer exhaust airflow
A clogged lint screen housing, blower outlet, or vent makes heat build up fast. The dryer may run briefly, then a high-limit device opens and the machine shuts down.
Quick check: Run a short timed cycle with the vent disconnected from the back of the dryer only if you can vent safely into an open area for a minute or two. If it stays on longer and airflow at the outlet is strong, the vent path is the problem.
2. Failed dryer door switch or loose door catch
If the switch is not proving the door is closed, the dryer may stop the moment vibration starts or when you release the start button.
Quick check: Open and close the door slowly. A solid latch and a crisp switch click fit normal operation. A mushy latch, no click, or a dryer that cuts out when you press on the door points here.
3. Broken dryer drum belt or tripped dryer belt switch
On many dryers, a broken belt stops drum movement and opens a safety switch so the motor will not keep running.
Quick check: If the drum suddenly turns with almost no resistance by hand and the dryer stopped abruptly, suspect a broken belt path.
4. Failing dryer drive motor overheating internally
A weak motor may start cold, then trip its internal overload after a few minutes. It often comes with humming, slow starts, or a hot electrical smell.
Quick check: Listen for a strained start, squeal, or hum before shutdown. If airflow is good and the dryer still quits hot, the motor moves up the list.
Step-by-step fix
Step 1: Match the shutdown pattern before opening anything
The timing tells you whether to chase airflow, a safety switch, or a motor problem. That saves a lot of wrong parts.
- Unplug the dryer or switch off power before touching anything beyond the controls and door.
- Try one short timed cycle and watch what happens: stops immediately, stops when you release Start, or stops after several minutes.
- Note whether the drum turns, whether heat is present, and whether the cabinet gets unusually hot.
- Check whether the door feels loose, bounces open slightly, or needs to be pushed to keep the dryer running.
Next move: If the pattern is clear, move to the matching checks instead of guessing. If the symptoms are random every time, start with airflow anyway because it is still the most common and least destructive check.
What to conclude: Immediate shutdown usually points to a door, belt, or motor start problem. A delayed shutdown points much more strongly to overheating from poor airflow or a motor that fails hot.
Stop if:
- You smell burning insulation or see smoke.
- The plug, cord, or outlet looks scorched.
- The dryer is gas-fired and you smell gas.
Step 2: Clear the easy airflow restrictions first
Dryers shut themselves down when they cannot shed heat. Lint buildup is common, visible, and fixable without buying parts.
- Remove the lint screen and wash it with warm water and a little mild dish soap if it has fabric-softener residue. Dry it fully before reinstalling.
- Look down into the lint screen housing and remove packed lint by hand or with a vacuum crevice tool.
- Pull the dryer forward and inspect the exhaust connection for a crushed or kinked vent hose.
- Disconnect the vent from the dryer and check for heavy lint right at the outlet collar.
- If safe, run the dryer for a minute or two with the vent disconnected to compare runtime and airflow at the dryer outlet.
Next move: If the dryer now stays running longer with the vent disconnected, the dryer itself may be fine and the vent path needs to be cleared. If it still shuts off the same way with the vent disconnected, move on to the door, belt, and motor checks.
What to conclude: A big improvement with the vent off is a strong airflow diagnosis. No change means the problem is likely inside the dryer cabinet or in a safety switch path.
Step 3: Check the door switch and latch behavior
A weak door switch can mimic bigger failures and often shows itself with a simple feel-and-listen check.
- With power off, open and close the dryer door several times and listen for a distinct switch click.
- Inspect the door strike and latch area for cracks, looseness, or a door that sits crooked.
- Start the dryer and gently press on the door near the latch. Do not force it. See whether the dryer cuts in and out with door movement.
- If the dryer only runs while holding the start button and the door switch feel is weak or inconsistent, suspect the dryer door switch first.
Next move: If pressing or repositioning the door changes the symptom, you have a strong door-switch or latch clue. If the door feels solid and the symptom does not react to door movement, keep going to the belt and motor checks.
Step 4: Decide whether the belt path or motor is the better fit
These two failures can both stop the dryer, but they leave different clues in the way the drum feels and sounds.
- With power disconnected, turn the drum by hand. It should have some steady resistance, not spin completely loose and not feel jammed.
- If the drum turns very freely with almost no resistance, suspect a broken dryer drum belt or belt-switch issue.
- If the drum is hard to turn, drags, or squeals, the motor may be overloading from seized support parts or the dryer drive motor itself may be failing.
- Run one more brief test only if safe: listen for a hum, slow start, or a motor that quits once it gets hot.
Next move: If the drum is loose, the belt path is your best lead. If it starts strained and dies hot, the motor is the stronger lead. If neither clue is clear, avoid buying parts blindly and move to the final decision step.
Step 5: Make the repair call based on the strongest clue
By now you should know whether this is a vent problem, a switch problem, a broken belt path, or a motor that fails hot.
- If the dryer stays on longer with the vent disconnected, stop using it until the full vent path is cleared and airflow is restored.
- If the dryer cuts out with door movement or only runs while holding Start, replace the dryer door switch after confirming the latch is not the real issue.
- If the drum turns too freely and the dryer stopped suddenly, inspect and replace the dryer drum belt and check whether the belt switch was tripped by the broken belt.
- If airflow is good, the door switch checks out, and the dryer runs briefly then quits hot with humming or slow starts, plan on a dryer drive motor repair or call a pro if cabinet teardown is beyond your comfort level.
A good result: Once the root cause is corrected, the dryer should complete a timed cycle without shutting off early.
If not: If it still shuts down after airflow is restored and the switch, belt, and motor clues do not line up cleanly, stop guessing and have the dryer professionally diagnosed.
What to conclude: This narrows the problem to the most likely fix instead of turning the dryer into a parts experiment.

FAQ
Why does my dryer run for a few minutes and then shut off?
Most often, it is overheating from poor airflow. A clogged vent, packed lint housing, or crushed exhaust hose traps heat until a safety device opens and the dryer stops.
Why will my dryer only stay on while I hold the start button?
That usually points to a door switch problem, a belt-switch issue on some models, or a motor that is not fully taking over after startup. Start with the door latch feel and switch behavior because that is the easiest check.
Can a clogged vent make a dryer shut off completely?
Yes. Restricted airflow can make the dryer run hot enough to trip a thermal safety device or overheat the motor. It is one of the most common reasons a dryer starts and then quits.
Should I replace the thermal fuse right away?
Not until you have a reason. A blown dryer thermal fuse is often the result of overheating, and the overheating cause is frequently a blocked vent. If you replace the fuse without fixing airflow, the new one may fail again.
Is it safe to use the dryer if it keeps shutting off?
No, not until you know why. A dryer that shuts off hot, smells burnt, or has weak airflow can be a fire risk. Stop using it and correct the airflow problem or have it diagnosed.
