Dryer Won't Start – Causes & Solutions

Dryer Won't Start – Causes & Solutions

A dryer that won't start is a major inconvenience. Whether it's completely dead or just won't begin a cycle, most dryer start problems are caused by a few common parts you can replace yourself.

✓ Common Causes of Dryer Won't Start

1. Faulty Door Switch (Most Common)

The door switch tells the dryer the door is closed and it's safe to run. If it fails, the dryer won't start even though the door is closed.

2. Blown Thermal Fuse

The thermal fuse is a safety device that cuts all power if the dryer overheats. Once blown, the dryer won't start until the fuse is replaced.

3. Defective Start Switch

The start switch activates the motor when you press the start button. If it fails, pressing the button does nothing.

4. Broken Drive Belt

Some dryers won't start at all if the drive belt is broken, as a safety feature to prevent the motor from running without a load.

5. Failed Control Board or Timer

The control board or timer signals the motor to start. If it fails, the dryer won't respond to the start button.

✓ Troubleshooting Steps (Do These First)

  1. Check the power - Make sure the dryer is plugged in and the circuit breaker hasn't tripped. Electric dryers use 240V and may have two breakers
  2. Test the door switch - Open and close the door while listening for a click
  3. Check the thermal fuse - Test for continuity with a multimeter. No continuity = blown fuse
  4. Inspect the drive belt - Open the dryer and manually spin the drum. If it spins freely, the belt is likely broken
