Step-by-step troubleshooting

1. Check the Door Switch
   Do: Locate the door switch, usually near the door frame.
   Observe: Ensure the switch is not stuck or damaged.
   Means: If the switch is faulty, it may not signal the dryer to stop.
   Next: Test the switch with a multimeter. If it's not working, replace it.
2. Inspect the Control Panel
   Do: Examine the control panel for any visible damage.
   Observe: Look for burnt marks, loose wires, or broken buttons.
   Means: A malfunctioning control panel can cause the dryer to run continuously.
   Next: If damaged, consider replacing the control panel.
3. Test the Timer
   Do: Access the timer, usually located in the control panel.
   Observe: Check for any signs of wear or damage.
   Means: A faulty timer can prevent the dryer from stopping.
   Next: Use a multimeter to test the timer. Replace if necessary.
4. Check the Motor
   Do: Locate the motor, typically at the bottom of the dryer.
   Observe: Listen for unusual noises and check for overheating.
   Means: A malfunctioning motor can cause the dryer to run non-stop.
   Next: If the motor is faulty, replace it.
5. Examine the Drive Belt
   Do: Remove the dryer cabinet to access the belt.
   Observe: Check for wear, cracks, or damage.
   Means: A damaged belt can cause the dryer to spin continuously.
   Next: Replace the belt if it shows signs of wear.
6. Inspect the Idler Pulley
   Do: Locate the idler pulley near the motor.
   Observe: Check for any signs of wear or damage.
   Means: A faulty idler pulley can cause the dryer to run non-stop.
   Next: Replace the idler pulley if necessary.
7. Test the Thermal Fuse
   Do: Find the thermal fuse, usually near the heating element.
   Observe: Check for continuity using a multimeter.
   Means: A blown thermal fuse can cause the dryer to run continuously.
   Next: Replace the thermal fuse if it's blown.
8. Check the Main Control Board
   Do: Access the main control board, usually behind the control panel.
   Observe: Look for burnt marks or damaged components.
   Means: A faulty control board can cause the dryer to run non-stop.
   Next: Replace the control board if it's damaged.
