✓ Most Common Causes of a Dryer Not Starting

1. Faulty Door Switch

Symptoms: Dryer won't start at all. The door switch tells the dryer the door is closed and it's safe to run.

Solution: Test the door switch for continuity with a multimeter. If it's faulty, replace it. This is the #1 cause of a dryer not starting.

2. Blown Thermal Fuse

Symptoms: Dryer won't start or run. The thermal fuse is a safety device that cuts all power if the dryer overheats.

✓ How to Diagnose Why Your Dryer Won't Start

  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. Test with a multimeter for continuity. Replace if faulty.
  3. Check the thermal fuse: Located on the blower housing or heating element. Test for continuity. 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.
  5. Test the start switch: Use a multimeter to check for continuity when the button is pressed.

✓ Frequently Asked Questions

Why won't my dryer start when I press the button?

The most common causes are a faulty door switch, blown thermal fuse, bad start switch, or broken drive belt. Start by testing the door switch and thermal fuse with a multimeter.

How do I know if my dryer door switch is bad?

Test the door switch with a multimeter for continuity. Press the switch actuator – it should show continuity when pressed and no continuity when released. If it fails this test, replace it.

Can I replace a dryer door switch myself?

Yes! Replacing a door switch is one of the easiest dryer repairs. You'll need a screwdriver and about 15-30 minutes. Our parts specialists can guide you through the process.

Why does my dryer thermal fuse keep blowing?

A thermal fuse blows due to overheating, usually caused by a clogged dryer vent or restricted airflow. Always clean your vent system and check for airflow restrictions when replacing a thermal fuse.

How much does it cost to fix a dryer that won't start?

DIY parts typically cost $10-$80. Door switches run $15-$35, thermal fuses $10-$25, start switches $15-$30, and drive belts $15-$40. Professional repair can cost $150-$300+ including labor.
