There are various reasons to blame for the Samsung dryer won’t start issues.

The reason can differ from Dryer to Dryer; some dryers may not be working properly due to a malfunctioning dryer motor.

Similarly, some might not be starting due to a blown thermal switch.  

However, I have found that the Broken Idler pulley, Broken Drum belt, Malfunction motor, and Blown thermal switch behind the Samsung dryer won’t start issues.

In the next section, we will look at how to locate and fix these issues in detail. 

How to locate and fix the issues?

If your Samsung dryer doesn’t start, we first have to identify the issues.

Here I have listed some of the issues and step-wise procedures to locate these issues in your dryer including the solution.

1. Power Supply issues

As mentioned earlier, power supply issues are one of the major reasons behind the Samsung Dryer won’t start issues.

A stable power supply is very much essential in the Dryer. The Dryer cannot function properly if there is no stable power supply.

I recommend you check the power using a multimeter and make sure there is no problem. 


The power supply issues can be anything, including broken circuit breakers, damaged power cords, and other issues. Here are some issues that you can inspect in your Dryer. 

1.    Power cord is not plugged properly: The first thing you should ensure is that the dryer power cord is plugged in properly. The power cord can get worn out, and if you have used an extension cord, ensure it is properly plugged. 

2. Circuit breaker is tripped out: The next thing that you should inspect is the home circuit breaker box. If the circuit breaker is tripped out, make sure to reset it. 

3. Faulty start switch: If the dryer power switch is faulty or not working properly due to some reason Samsung dryer won’t start properly. You can inspect the button by removing the control access panel of the Dryer. These are some of the most likely power supply issues in your Dryer. Make sure to inspect these issues in your Dryer.

2. Door is not latched properly

Samsung Dryer won’t start with an open or loosely latched door.

Sometimes the obstruction can prevent you from closing the door properly.

You may have noticed a light that lights up when you open the dryer door. Make sure that the light is off when you are trying to start the Dryer. 


If your dryer door latch is not working or loose, secure it using the screwdriver. Similarly, if the door latch is not working or latching properly, consider replacing it with a new door latch. Follow the below instruction to replace the Samsung dryer door latch. 

  1. First of all, turn off the power supply of the Dryer. 
  2. Open the door of the Dryer and then locate the door latch. You can check the owner’s manual if you don’t know anything about the door latch. There you may even step-wise procedure to access the door latch of the Samsung dryer. 
  3. Once you locate the door latch, remove the door latch from the Dryer. There may be a couple of screws securing the latch on the Dryer. You need to use a screwdriver to remove the door latch from the Dryer. 
  4. Once you remove all the screw, remove the wire from the latch and pull it from the Dryer. 
  5. Now install the new door latch following the instructions, and don’t forget to connect the wire. 
  6. Once you are done connecting the wire to the new door latch, secure it tightly using the screw. 

This is the step-wise procedure to remove the old door latch and replace it with a new one.

I hope that the instruction has worked well in your model Dryer. If you encounter any issues during the installation, write them down below in the comment. 

3. Blown thermal switch

A thermal switch is a special type of switch that prevents the Dryer from being further damaged due to overheating or short circuits.

A blown thermal switch could be another reason to halt the Samsung dryer’s functioning.

Recently, if there was a power shortage or short circuit thermal switch could be the reason behind it.

Samsung dryer won’t start if the thermal switch is blown or damaged. 


Samsung dryer won’t start if the thermal switch is blown off or damaged.

Therefore, the solution to the blown thermal switch is the replacement.

You should replace your existing thermal switch with a new one. Here is the step-wise instruction to replace the thermal switch from the Samsung dryer. 

  1. For safety purposes, I recommend you unplug the Dryer from the power supply, or you can also flip the circuit breaker.
  2. Now pull the Dryer so that you can access the backside of the Dryer. 
  3. Unthread the screw securing the top panel of your dryer and set them aside. 
  4. 4.     Remove the two screws securing the front panel of the Dryer. 
  5. Open the dryer door and remove the two mounting screws from the Dryer.  
  6. Now on the top of the Dryer, you will see locking tabs. I recommend you depress it and pull the front panel forward. 
  7. Disconnect the door switch wire, lift off the panel, and disconnect the wire harness from the moisture sensor. 
  8. Remove the screw securing the mounting bracket and gently pull the mounting bracket from the Dryer. After this, pull the heating element housing from the dryer. 
  9. Now at the back of the housing element, you will find a thermal switch connected with a wire. 
  10. Remove the wire harness from the Dryer and unthread the screw securing the thermal switch. 
  11. Pull the thermal switch and install the new switch following the same instruction. 
  12. Once you are done installing the thermal switch, make sure to secure it using the screwdriver. 
  13. Install the heating element housing and secure it using the mounting bracket on your Dryer. 
  14. Install a mounting screw in the dryer door and also install the control panel of your Dryer. 

I recommend you follow the above-discussed step-wise instructions to replace the thermal switch from your Samsung dryer. 

4. Idler Pulley is Broken

The idler pulley plays an important role in spinning the Dryer at high speed.

The pulley is called “idler pulley” and “tension pulley.” It sits on an arm, and the drive belt wraps around the wheel.

Over time the pulley can get worn or crack, which can lead to the Samsung dryer won’t start issue in the Dryer. 


If there is a crack or damage on the idler pulley, you should replace it with a new belt.

The process of replacing the idler pulley is a bit difficult and tricky, so I recommend you contact appliance technicians.

A damaged idler pulley produces a weird or unusual sound. 

5. Drum belt broken

Drum belt could be another reason behind Samsung Dryer won’t start issues.

This belt holds or ties the dryer drum, which makes it easy to spin the drum during the operation.

The belt is made up of using rubber which makes it very easy to keep in tension while maximizing the ability to spin the drum.

Over a long period, the belt can get cracks due to moisture, dust, and water. 


If the drum belt is damaged or has some crack dryer may not work properly. The solution to this problem is replacing the drum belt.

You cannot replace the drum belt on your own as it requires proper knowledge of the Dryer and tools.

Therefore, I recommend you contact the appliance technicians for the replacement. 

6. Defective motor

The motor is a very important component of the Dryer it helps the dryer rotate the drum. Samsung dryer won’t start if the motor is defective or not working properly.

If your dryer motor is producing a humming or buzzing sound during the operation there is high chance of the start winding has burnt out.


The solution for the defective motor is a replacement. You cannot repair or fix the motor.

Moreover, it is one of the most important components of the dryer so I won’t recommend you replace the motor on your own.

It is better to contact an appliance technician for the replacement.

What to do if the Samsung dryer won’t start?

If the Samsung dryer is still not working or starting, don’t worry. Most Dryer comes with a couple of years of warranty support that can help you repair your dryer free of cost.
