There can be several reasons why a clothes dryer may stop running after a few minutes. Here are some common causes:
Overheating: Dryers have safety mechanisms to prevent overheating. If the appliance gets too hot, a thermal fuse or thermal cutoff may be triggered, shutting off the dryer to prevent a potential fire hazard.
Blocked or restricted airflow: Proper airflow is essential for efficient drying. If the dryer's air vents, lint trap, or exhaust ducts are clogged with lint or debris, it can cause the appliance to overheat and shut down.
Faulty motor: The dryer's motor might have an internal issue that causes it to overheat or malfunction, leading to the dryer shutting off automatically.
Malfunctioning thermostat: Dryers have temperature sensors, called thermostats, which regulate the heating element. If a thermostat is faulty or inaccurate, it can cause the dryer to overheat or not heat properly, leading to a shutdown.
Door switch problems: Most dryers have a safety feature that stops the dryer from running when the door is open. If the door switch is faulty or not making proper contact, the dryer may stop running mid-cycle.
Circuit or power issues: Electrical problems, such as a tripped circuit breaker or a loose power connection, can cause the dryer to stop working suddenly.
Timer or control board malfunction: If the timer or control board of the dryer is defective, it might interrupt the drying cycle prematurely.
To troubleshoot and diagnose the specific problem, it's essential to check each of these components thoroughly. If you are not familiar with appliance repairs, it's best to seek the assistance of a professional technician to avoid any safety risks and ensure proper repairs.
