If your dryer keeps starting and stopping abruptly during a cycle, there could be various reasons behind this issue. Here are some steps you can take to troubleshoot and potentially fix the problem:
Check for Overloading: Overloading the dryer can cause it to start and stop repeatedly. Ensure that you're not putting too many clothes in the dryer, as this can strain the motor and trigger safety features.
Clean the Lint Filter and Vents: A clogged lint filter or vents can restrict airflow, causing the dryer to overheat and shut off intermittently. Clean the lint filter before every load and inspect the vents regularly for blockages.
Verify Power Supply: Make sure the dryer is adequately connected to a stable power supply. Check the power cord for any visible damage or loose connections.
Examine the Door Switch: The door switch is a safety feature that prevents the dryer from running if the door is open. Check if the door is fully closed and the switch is working correctly.
Check the Thermal Fuse: The thermal fuse is a safety device that protects the dryer from overheating. If it's blown, the dryer won't run. Use a multimeter to test the thermal fuse for continuity, and if it's faulty, replace it with a new one.
Inspect the Drive Belt: A worn or damaged drive belt can cause the dryer drum to stop spinning, resulting in the start-stop behavior. Look for signs of wear, such as fraying or cracks, and replace the belt if necessary.
Test the Start Switch: The start switch can wear out over time, leading to intermittent operation. Use a multimeter to check if the start switch is functioning correctly. If it's faulty, replace it.
Verify the Motor: A malfunctioning motor may cause the dryer to stop during a cycle. Test the motor's continuity using a multimeter and replace it if it's defective.
Inspect the Control Board: A faulty control board can cause erratic behavior in the dryer. Check for any visible damage on the control board and consider replacing it if necessary.
Thermistor Inspection: The thermistor monitors the temperature inside the dryer. If it's defective, it can lead to irregular operation. Test the thermistor for continuity and replace it if needed.
If you're not familiar with electrical appliance repairs, it's essential to consult the dryer's user manual or seek the assistance of a qualified appliance technician. They can diagnose the specific issue with your dryer and perform any necessary repairs safely. Remember to unplug the dryer before attempting any troubleshooting or repairs to ensure your safety.
