There could be several reasons why a clothes dryer stops running after only a few minutes:
Overheating: Dryers have built-in safety mechanisms that shut off the machine if it gets too hot. Overheating can occur due to various reasons, such as clogged vents, lint buildup, or a malfunctioning thermostat. When the dryer's temperature reaches a critical point, it automatically shuts down to prevent the risk of fire.
Thermal fuse issue: The thermal fuse is another safety component in the dryer that prevents overheating. If the thermal fuse is faulty or blown, the dryer will stop running shortly after starting.
Clogged lint filter or vent: A clogged lint filter or vent restricts airflow, causing the dryer to overheat. Many dryers have sensors that monitor airflow, and if it's insufficient, the machine will shut down as a safety precaution.
Faulty motor: A malfunctioning dryer motor can lead to overheating, causing the machine to shut off. This issue may require professional repair or motor replacement.
Defective start switch or timer: If the start switch or timer is faulty, it can interrupt the dryer's operation after a short time.
Electrical issues: Problems with the electrical supply or the dryer's power cord can cause the machine to shut down abruptly.
Load imbalance: If the load inside the dryer is unevenly distributed or too heavy, the machine's safety mechanisms may stop the cycle to prevent damage.
If your dryer keeps stopping after a few minutes, it's essential to troubleshoot the issue to identify the underlying cause. Here are some steps you can take:
Check for overheating: Make sure the dryer is adequately ventilated and free from lint buildup. Clean the lint filter, exhaust vent, and any other areas where lint might accumulate.
Inspect the thermal fuse: If the dryer is not getting too hot, the thermal fuse might be the problem. A multimeter can be used to check its continuity. If the thermal fuse is faulty, it should be replaced.
Examine the motor and other components: If you suspect a faulty motor or other issues, it's best to contact a qualified appliance repair technician to inspect and diagnose the problem accurately.
Verify the electrical supply: Ensure the dryer is correctly connected to a reliable power source.
If you're not comfortable troubleshooting the dryer on your own or if the issue persists after attempting the above steps, it's best to seek assistance from a professional appliance repair technician. They can diagnose and fix the problem safely and effectively.
