Confirm the symptom
- Dryer is plugged in and has power (lights, display working).
- Dryer does not start when you press the start button.
- No unusual noises or smells when attempting to start.
Tools and prep
- Screwdrivers (flathead and Phillips).
- Multimeter for testing electrical components.
- Owner's manual for your dryer model.
- Work gloves for safety.
- Turn off the dryer and unplug it before starting.
Step-by-step troubleshooting
- Check Power SupplyDo: Ensure the dryer is plugged in and the outlet is working.Observe: Outlet has power and dryer is properly connected.Means: Power supply is not the issue.Next: Check the door switch.
- Test Door SwitchDo: Open and close the dryer door to see if the switch is functioning.Observe: The dryer starts when the door is closed.Means: Door switch is working.Next: Check the thermal fuse.
- Inspect Thermal FuseDo: Use a multimeter to test the thermal fuse for continuity.Observe: Multimeter shows no continuity.Means: Thermal fuse is blown and needs replacement.Next: Replace the thermal fuse.
- Check Start SwitchDo: Test the start switch with a multimeter for continuity.Observe: No continuity when the switch is pressed.Means: Start switch is faulty.Next: Replace the start switch.
- Inspect MotorDo: Test the motor with a multimeter for continuity.Observe: No continuity in the motor.Means: Motor is faulty and needs replacement.Next: Replace the motor.
- Check Circuit BreakerDo: Inspect the circuit breaker to ensure it hasn't tripped.Observe: Circuit breaker is in the 'on' position.Means: Circuit breaker is not the issue.Next: Check for other electrical issues.

Use a multimeter to test for continuity. If there is no continuity, the thermal fuse is blown and needs replacement.
What should I do if the dryer motor is faulty?
If the motor is faulty, it will need to be replaced. This is a more complex repair and may require professional assistance.
Why is my dryer not starting even though the door is closed?
The door switch may be faulty. Test the switch with a multimeter to check for continuity.
Can a faulty timer cause the dryer not to start?
