Quick answer

If your dryer has power but won't start, first check the door switch, power cord, and thermal fuse. If these are fine, the motor or control board may need a technician.

Confirm the symptom

Dryer has power (lights, display working)
Dryer does not start when you press Start
No unusual sounds or smells when trying to start
Power cord is plugged in and outlet works

Tools and prep

Multimeter (for testing electrical components)
Screwdrivers (flathead and Phillips)
Owner's manual for reference
Safety gloves and goggles
Dryer unplugged from power source

Step-by-step troubleshooting

Check the Door Switch
Do: Locate the door switch near the dryer door opening and test it with a multimeter.
Observe: If the switch is broken or not closing properly, it will prevent the dryer from starting.
Means: The door switch is faulty and needs replacement.
Next: Replace the door switch.
Inspect the Power Cord
Do: Examine the power cord for visible damage and test the cord with a multimeter.
Observe: A damaged or faulty power cord will not transmit electricity properly.
Means: The power cord is damaged and needs replacement.
Next: Replace the power cord.
Test the Thermal Fuse
Do: Locate the thermal fuse (usually on the exhaust duct) and test it with a multimeter.
Observe: If the thermal fuse is blown, it will not conduct electricity.
Means: The thermal fuse is blown and needs replacement.
Next: Replace the thermal fuse.
Check the Motor
Do: Test the dryer motor with a multimeter for continuity.
Observe: If the motor does not have continuity, it is not receiving power.
Means: The motor is faulty and needs replacement.
Next: Replace the motor or call a professional.
Inspect the Control Board
Do: Check the control board for visible damage or burn marks and test it with a multimeter.
Observe: If the control board is damaged or not functioning, it will not send power to the motor.
Means: The control board is faulty and needs replacement.
Next: Replace the control board or call a professional.
Check the Start Switch
Do: Test the start switch with a multimeter to ensure it is functioning properly.
Observe: If the start switch is faulty, it will not send power to the motor.
Means: The start switch is faulty and needs replacement.
Next: Replace the start switch.

Common causes

Cause	Likelihood	Difficulty	Part often needed
Faulty Door Switch The door switch ensures the door is closed before starting. If it's broken, the dryer won't start.	Common	Easy	Door Switch
Damaged Power Cord A damaged power cord can prevent electricity from reaching the dryer's components.	Common	Easy	Power Cord
Blown Thermal Fuse The thermal fuse is a safety device that blows if the dryer overheats, cutting off power to prevent fires.	Common	Easy	Thermal Fuse
Faulty Motor The motor may be damaged or burned out, preventing the dryer from starting.	Sometimes	Medium	Dryer Motor
Faulty Control Board The control board sends power to the motor and other components. If it's damaged, the dryer won't start.	Sometimes	Hard	Control Board
Faulty Start Switch The start switch initiates the dryer's operation. If it's faulty, the dryer won't start.	Sometimes	Easy	Start Switch

FAQ

Why does my dryer have power but won't start?

This can be caused by a faulty door switch, damaged power cord, blown thermal fuse, or issues with the motor or control board.

Can I test the thermal fuse myself?

Yes, you can test the thermal fuse with a multimeter. If it's blown, it will need to be replaced.

How do I know if the dryer motor is bad?

If the motor doesn't have continuity when tested with a multimeter, it is likely faulty and needs replacement.

Is it worth repairing an old dryer that won't start?

It depends on the cost of the repair versus the value of the dryer. If the repair is expensive, it may be more cost-effective to replace the dryer.
