Why Is My Dryer Not Working?

Dryer 8

A dryer is a handy appliance that saves us a lot of time by drying our clothes quickly. But like any other appliance, it can sometimes stop working, leaving us with wet clothes and a lot of questions. If you’re asking yourself, “Why is my dryer not working?”, you’re in the right place. In this comprehensive guide, we’ll explore the common issues that can cause your dryer to malfunction and provide potential solutions to get it up and running again.


Your dryer may not be working due to a variety of reasons including a faulty door switch or start switch, power issues, a clogged exhaust vent, a faulty thermal fuse, a broken drive belt, or worn drum rollers or a faulty motor. Troubleshooting can involve checking these components for damage or wear and replacing them if necessary. If problems persist, it’s best to consult a professional appliance repair service. Regular maintenance and cleaning can help prevent many common dryer issues.

Common Reasons for Dryer Issues

There could be several reasons why your dryer might stop working. Let’s go through some of the most common ones:

Faulty Door Switch or Start Switch

The door switch is a safety feature that prevents the dryer from operating when the door is open. If this switch is faulty, the dryer won’t start. Similarly, if the start switch is defective, it can prevent the dryer from running.

Power Issues

Check the plug, power cord, and breakers to ensure the dryer is securely plugged in and there is no damage or wear to the plug or cord. A tripped circuit breaker can also cause your dryer to stop working.

Clogged Exhaust Vent

A clogged exhaust vent can cause the dryer to overheat, which can lead to the thermal fuse blowing, preventing the dryer from heating. Regular cleaning of the vent can prevent this issue.

Faulty Thermal Fuse

A blown thermal fuse can cause the dryer to stop running or not heat up. This is a safety device that prevents the dryer from overheating.

Broken Drive Belt

The drive belt wraps around the dryer drum and a pulley on the motor, and as the motor spins, it turns the drum. If the drive belt is broken, the drum won’t spin.

Worn Drum Rollers or Faulty Motor

Worn drum rollers or a faulty motor can cause the dryer to make loud noises or vibrate excessively.

Troubleshooting Steps

If you’re experiencing issues with your dryer, follow these steps to troubleshoot and fix the problem:

  1. Unplug the dryer: Always disconnect the power before attempting any repairs.
  2. Check the door switch and start switch: Inspect these switches for any signs of damage or wear.
  3. Inspect the power cord and breakers: Make sure the dryer is securely plugged in and the circuit breaker hasn’t tripped.
  4. Clean the exhaust vent: A clogged vent can cause the dryer to overheat. Regular cleaning can help prevent this.
  5. Test the thermal fuse: Use a multimeter to check the thermal fuse for continuity. Replace it if it’s blown.
  6. Check the drive belt: Inspect the drive belt for any signs of wear or damage. Replace it if needed.
  7. Inspect the drum rollers and motor: Check these components for any issues. Replace or repair them as necessary.

If you’re still experiencing issues with your dryer after trying these troubleshooting steps, it’s best to consult a professional appliance repair service for further assistance.

When to Call a Professional

While some minor issues can be fixed with a little DIY spirit, certain problems are best left to professionals. If your dryer is moving around, making unusual noises, overheating, or if you smell burning, it’s time to call in a professional.

Remember, regularly cleaning and maintaining your dryer can prevent many common issues from occurring in the first place. Check the lint filter regularly, clean the exhaust vent annually, and avoid overloading your dryer. By following these steps, you can ensure your dryer remains in good working condition for years to come.

Frequently Asked Questions

How often should I clean the lint filter in my dryer?

You should clean the lint filter after every load of laundry. This helps to prevent clogs and keeps the dryer running efficiently.

How can I tell if my dryer’s start switch is faulty?

If the dryer does not respond or make any noise when the start switch is pressed, it might be faulty. You can use a multimeter to test the switch for continuity. If it doesn’t have continuity, it needs to be replaced.

What should I do if my dryer is overheating?

If your dryer is overheating, it could be due to a clogged vent or a faulty thermal fuse. Check and clean the vent first. If the problem persists, test the thermal fuse with a multimeter. If it’s faulty, replace it. If you’re still having issues, it’s best to call a professional.

How can I tell if my dryer’s drive belt is broken?

If your dryer’s drum is not spinning but you can hear the motor running, the drive belt may be broken. You’ll need to open the dryer cabinet to inspect the belt.

Why is my dryer making loud noises?

Loud noises from your dryer can be caused by worn drum rollers or a faulty motor. If the noise is a thumping sound, it’s likely due to worn drum rollers. If the noise is a humming or buzzing sound, it could be a faulty motor.
