Hi Sally, thank you for getting in touch regarding your Samsung dryer.
When a dryer starts and then shuts off shortly after, it is often due to overheating protection triggered by restricted airflow. Lint buildup in the exhaust vent system, including areas beyond the lint filter, can cause this even with regular cleaning. If airflow is clear and the issue continues, resetting the dryer by unplugging it or turning off the circuit breaker briefly can help rule out a temporary control issue, though a reset will not resolve airflow or sensor-related conditions.
