Stops as soon as you release Start
The dryer may run only while you hold the button, or it starts and dies almost immediately.
Start here: Focus on the door switch or latch not staying made, and confirm the door closes tight without bounce.
Direct answer: When a dryer starts and then stops, the first things I check are airflow restriction, an overloaded drum, and a weak door-latch signal. If it quits after getting hot, an overheating safety is much more likely than a bad timer or board.
Most likely: The most common cause is the dryer overheating because lint has choked the lint screen housing or vent path, which can trip a dryer thermal fuse or high-limit safety.
Pin down when it stops: right after you press Start, after a few seconds of tumbling, or only once the cabinet gets hot. That timing tells you whether you’re dealing with a door-switch issue, drag in the drum, or an overheat shutdown. Reality check: a lot of these turn out to be airflow, not a failed major part. Common wrong move: replacing the heating parts before checking the vent and lint buildup.
Don’t start with: Don’t start by ordering a dryer control board or gas valve parts. Those are not the usual reason a dryer runs briefly and then shuts down.

The drum turns normally at first, then the dryer quits before the load is dry.
Start here: Check for restricted airflow and overheating first, especially a packed lint path or crushed vent hose.
Small loads may finish, but towels or jeans make it shut down early.
Start here: Look for a dragging drum, worn support parts, or a weak motor that drops out under load.
The dryer will restart later after sitting, but repeats the same shutdown.
Start here: That points strongly to overheating or a motor thermal protector opening, usually from poor airflow or a failing motor.
This is the most common field find. The dryer heats up, cabinet temperature climbs, and a safety opens or the motor overheats.
Quick check: Run a short test with the vent disconnected from the back of the dryer. If it stays running and airflow at the outlet is strong, the vent path is the problem.
If the door has play, the catch is loose, or the switch is weak, vibration can break the run circuit and stop the dryer early.
Quick check: Close the door firmly and push on the door corner while starting. If the dryer behavior changes, inspect the latch and door-switch area.
A tired motor may start cold, then open its internal protector once it warms up or once the drum load increases.
Quick check: With power off, turn the drum by hand. If it feels stiff, rough, or hard to start, the motor may be struggling against drag.
After repeated overheating, one of the dryer safeties can open and cause no-run or short-run complaints.
Quick check: If airflow is poor and the dryer has been running very hot, inspect and test the dryer thermal fuse and high-limit thermostat after unplugging the unit.
A dryer that dies the instant you release Start is a different problem than one that quits only after it gets hot. Sorting that out first saves a lot of wasted parts.
Next move: If the pattern is now clear, move to the matching checks below instead of guessing at parts. If the behavior is random and you cannot repeat it, start with airflow and door-latch checks anyway because those are still the most common and least invasive.
What to conclude: Immediate shutoff points more toward the door-switch side. Hot shutdown after some run time points more toward airflow, safeties, or the motor overheating.
Poor airflow is the top reason a dryer runs briefly and then shuts off hot. It also causes repeat failures of thermal fuses and thermostats if you skip the vent problem.
Next move: If the dryer now keeps running with the vent disconnected, fix the house vent restriction before replacing any dryer parts. If it still shuts off the same way with the vent disconnected, the problem is likely inside the dryer or at the door-switch side.
What to conclude: A dryer that behaves better with the vent off is overheating from restricted exhaust, not from a mystery electronic failure.
A weak door switch can cut power from vibration, and a dragging drum can overload the motor enough to make it trip out.
Next move: If pressing on the door changes the symptom, or if the drum feels rough and tight, you have narrowed it to the door-switch area or a motor/drag problem. If the door is solid and the drum turns freely, move on to the overheat safety checks.
Once airflow has been poor for a while, the dryer thermal fuse or high-limit thermostat becomes a realistic repair path. This is where parts start to make sense.
Next move: If the dryer thermal fuse is open, replace the dryer thermal fuse after the vent and lint path are corrected. If the high-limit thermostat tests open, replace the dryer high-limit thermostat. If both test good and airflow is no longer restricted, the motor becomes the stronger suspect, especially if the dryer quits hot and restarts later.
At this point the common easy causes are sorted. The remaining call is usually a confirmed safety replacement or a motor problem that takes more teardown.
A good result: If the dryer completes a full heated cycle without shutting off, the repair path was correct.
If not: If it still stops hot after airflow correction and safety checks, stop spending money on guess parts and have the motor circuit diagnosed.
What to conclude: A repeat hot shutdown with good airflow and good safeties is classic weak-motor territory. An immediate stop with door movement involved is still a door-switch problem until proven otherwise.

Most often it is overheating from restricted airflow. A clogged vent, packed lint housing, or crushed vent hose makes the dryer run hot until a safety opens or the motor overheats and drops out.
Usually an open dryer thermal fuse causes a no-run condition, but on some complaints the fuse or another safety has been weakened by overheating and shows up after short-run behavior. Test it rather than guessing.
That is a strong clue the motor is overheating internally or the dryer is running too hot from poor airflow. Cooling down lets the protector reset, but the problem will come back until the cause is fixed.
Not first. A heating element is not the usual reason a dryer starts then stops. Check airflow, the door signal, and the thermal safeties before spending money on heating parts.
Yes. In the field, that is one of the most common reasons. Poor exhaust flow traps heat in the dryer, and the machine protects itself by opening a safety or overheating the motor.
No. Intermittent hot shutdowns often mean restricted airflow or overheating, and that can damage parts or create a lint-fire risk. Fix the airflow issue or have the dryer checked before regular use.
