A dryer not starting can be due to a blown thermal fuse or a faulty door switch. To fix the issue, check and replace these parts as necessary.
When your dryer won’t start, the inconvenience can put a standstill on your laundry routine. The most common reason for a dryer not starting is a blown thermal fuse. It’s a safety component that cuts off power to the dryer if it overheats.
Another possible culprit is a faulty door switch. It prevents the dryer from starting if the door isn’t fully closed. These parts require careful attention and replacement to get your dryer running again. In this article, we’ll cover how to diagnose and fix these issues to get your dryer back up and running.
Common Causes Of A Dryer Not Starting
Dryers are an essential appliance in our modern-day homes. They save us time and effort by quickly and efficiently drying our clothes. However, there can be situations where your dryer may fail to start, and this can be frustrating. In this blog post, we will discuss the common causes of a dryer not starting to help you troubleshoot the issue effectively.
Dead Power Outlet Or Circuit Breaker Tripping
Sometimes, the dryer may not start due to issues with the power supply. The first thing to check is the power outlet; you can do this by plugging a different appliance like a lamp or phone charger. If other devices work fine in the same outlet, the issue may be with the dryer itself.
Check the circuit breaker box and see if the breaker has tripped. If so, flip the switch back and try starting the dryer again.
Defective Door Switch
If the dryer does not respond after plugging into an active power outlet and ensuring that the circuit breaker is okay, the next suspect is the door switch. When you close the dryer door, the switch is triggered, and the dryer starts running.
A faulty door switch may not detect the door’s closure, preventing the dryer from starting. Inspect the door switch for any signs of wear or damage, and if necessary, consider replacing it.
Burnt Out Thermal Fuse
The thermal fuse is a safety device that helps prevent overheating of the dryer’s heating element. If the fuse blows, the dryer will not start. Typically, a thermal fuse will blow if it senses that the dryer is overheating. Check the thermal fuse for continuity using a multimeter, and if it’s blown, replace promptly with a new one.
Faulty Drive Belt
A broken or faulty drive belt can restrict the drum’s movement, thus preventing the dryer from starting. Inspect the drive belt for any signs of wear or damage, such as cracks or frayed edges. If the drive belt looks worn out, replace it with a new one.
The timer is responsible for controlling various dryer settings, such as cycle times and temperature settings. If the timer malfunctions, it can prevent the dryer from starting, even when it’s plugged in and receiving power. Check the timer for any signs of damage or wear and replace it if necessary.
Broken Motor Switch
The motor switch is located near the motor and is responsible for turning the dryer drum. A broken motor switch will prevent the dryer from starting, and the drum will not turn. Inspect the motor switch for any visible damage and replace it if needed.
A dryer that won’t start can be frustrating, but troubleshooting the issue can help you identify the problem and fix it. By following the steps outlined in this blog post, you can get your dryer up and running again in no time.
Always ensure safety precautions while handling any electric home appliance.

To check the timer continuity, follow these steps:
- Unplug the dryer and locate the timer.
- Use the multimeter to check for continuity in the timer.
- If there is no continuity, the timer needs to be replaced.
Diagnosing A Broken Motor Switch
If all of the above components are functioning properly, the problem could be a broken motor switch. Here are the steps to diagnose a broken motor switch:
- Unplug the dryer and locate the motor.
- Use the multimeter to check for continuity in the motor switch.
- If there is no continuity, the motor switch needs to be replaced.

If you don’t have any experience repairing dryers or any electrical appliances, fiddling with your dryer can cause more harm than good. Hiring a certified technician with the right knowledge and experience is essential to avoid causing more damage to your dryer.
- You should consider seeking help from a qualified and licensed technician if you have no experience repairing electrical appliances.
Complex Dryer Problems
While some dryer problems are easy to fix, some are complex and require the help of professionals. Such issues might include faulty dryer motors, complicated electrical problems, or other intricate technical problems. Handling such problems without the proper tools, skills, and knowledge can be hazardous.
- If your dryer has complex problems that require technical expertise, it’s advisable to seek help from an experienced technician.
Safety Concerns And Potential Hazards
Handling any electrical appliance without proper safety precautions may result in accidents, including electrical shocks, fires, or even injuries. Because dryers require electricity to operate, it’s necessary to proceed with caution.
- If you notice any loose wiring, strange odors, or smoke coming from your dryer while in use, call a qualified technician immediately.
Warranty Or Manufacturer Restrictions
It’s important to note that if your dryer is new, or still under warranty or manufacturer restrictions, attempting to repair it yourself can void the warranty. If you do so, it will likely make it impossible to cover future repairs or replacements that are available to you.
- If your dryer is still under warranty or manufacturer restrictions, contact the authorized service center for assistance.
It’s always better to be cautious and safe, especially when dealing with electrical appliances. If your dryer has complex, technical, or electrical issues, it’s best to call a qualified and experienced repair technician instead of trying to fix the issue yourself.
Remember, safety should be your top priority when dealing with potentially dangerous situations.
