Dryer Not Starting – Complete Troubleshooting and Repair Guide
If your dryer will not start, the problem may be electrical or mechanical. The dryer may appear completely unresponsive when the start button is pressed, or it may produce clicking or humming sounds without beginning the drying cycle.
Fortunately, many dryer start problems are caused by a few common components that can be diagnosed and replaced.

When the start button is pressed, electrical power flows through several safety switches and components before reaching the motor.
The start system includes:
- Door switch

The dryer will not start if the door switch does not detect that the door is closed.

If the dryer motor fails, the drum will not spin.
Defective Start Switch
The start switch may fail after years of use.
