There are several possible reasons why a dryer may stop working after running for only a few moments. Here are some common issues that could cause this problem:
Overheating: Dryers have thermal safety features that shut off the machine if it gets too hot. This can be caused by a clogged lint filter or vent, restricted airflow, or a malfunctioning thermostat. The safety mechanism activates to prevent potential fires or damage to the dryer.
Faulty thermal fuse: The thermal fuse is another safety component that cuts off power to the dryer if it overheats. If the thermal fuse is faulty or blown, it will interrupt the power supply to the dryer, causing it to stop shortly after starting.
Clogged vent or exhaust hose: A blocked vent or exhaust hose restricts the airflow, leading to overheating. Regularly clean the vent and exhaust hose to ensure proper ventilation.
Defective door switch: The dryer's door switch ensures that the machine stops when you open the door. If the switch is malfunctioning or not engaging properly, it may cause the dryer to stop running.
Drive belt issues: The dryer's drive belt is responsible for turning the drum. If the belt is worn, loose, or broken, it can cause the drum to stop spinning, resulting in the dryer shutting down.
Motor problems: A malfunctioning motor can cause the dryer to stop abruptly. Motor issues may be related to electrical problems or mechanical failure.
Electrical issues: Loose connections, a tripped circuit breaker, or a faulty power outlet can cause the dryer to stop running.
Control board malfunction: If the control board or electronic components of the dryer are faulty, it may cause the machine to shut off unexpectedly.
To troubleshoot the issue and find the exact cause of the problem, you can try the following steps:
Check the lint filter and vent: Clean the lint filter before each load, and inspect the vent and exhaust hose for any obstructions.
Verify the power supply: Make sure the dryer is properly connected to a functional power outlet, and check for any tripped circuit breakers.
Inspect the door switch: Open and close the dryer door to check if the door switch is engaging properly.
Test the thermal fuse and thermostat: Use a multimeter to check the thermal fuse and thermostat for continuity. If they are faulty, they will need to be replaced.
Examine the drive belt: Inspect the drive belt for any signs of wear or damage. If needed, replace the belt.
If you're not comfortable troubleshooting or making repairs yourself, it's best to consult a professional appliance repair technician to diagnose and fix the issue safely.
