However, every electronic device is prone to some issues after being used for a while, and dryers are no different. Just like you can find some errors in Samsung washing machines, dryers can also have some problems.

So, if you’ve been using one for a long time, chances are high that you are or could be dealing with the problem of the Samsung dryer not heating.

In that case, you can read this write-up in its entirety to find out the reasons behind the issue and the best solutions to try!

Quick Answer The most common cause for a Samsung dryer not heating is a faulty thermistor or thermostat. You can check the continuity with a multimeter and see if it needs replacement or not.

Top 10 Causes for Samsung Dryer not Heating With Solutions

If your dryer is taking longer to show the results or not working at all, you may wonder “Why is my Samsung dryer not drying,”. So, before contacting the technician, it is better to take a look at the common causes mentioned below and try troubleshooting yourself.

Connectivity Issues

First of all, any electric appliance will need a steady flow of electricity to operate well. When it comes to Samsung dryers, most of them won’t produce enough if there’s a problem with the power supply. 

Power supply

So, before you start examining the internal parts, ensure that there’s no Electric fluctuation or leakage that can disrupt its error-free functioning. In addition, you can look for any physical damage at the back of the machine.

When you make sure that there are no physical damages and the flow of electricity has been constant, proceed to the next steps.

Blown Thermal Cut-Off Fuse

A thermal cut-off fuse is a component in dryers that protects them from overheating. So, when the dryer overheats, the cut-off fuse is blown to avoid any repercussions from overheating. As a result, the machine fails to produce heat after the fuse melts, and the only solution is its replacement.

Thermal fuses are disposable components that must be replaced after their purpose is fulfilled. However, you must ensure that the power is off before you begin the process and that you’re referring to the user guide or technical sheet for assistance.

Malfunctioning of the Flame Sensor 

The malfunctioning of the flame sensor can be another reason the dryer is not heating up. However, it is only possible if you’re using a gas-powered one and the flame sensor is not working properly.

Flame Sensor of a dryer

Here’s how you can fix it:

  • Cut off the power supply to the dryer.
  • Remove the top and side panels so that you can reach the flame sensor easily.
  • Check the sensor’s continuity with the help of a multimeter.
  • If it lacks continuity, the only solution is to replace it with a new one.

Moreover, you need to ensure that you’re performing these steps at room temperature.

Worn Out Gas Valve Solenoid

Another reason for a Samsung front load dryer not heating is a worn-out gas valve solenoid. The one that is gas-powered can have two or more gas-valve solenoid coils. These coils facilitate the gas flow, and their failure ensures that the machine won’t produce heat anymore.

 Gas Valve Solenoid

To find out if the gas valve solenoid is working or not, turn on the igniter and check if the gas is ignited. In addition, you need to keep an eye on the continuity if there’s no light produced by the igniter. If you notice no continuity between the two ends of the igniter, you must replace it.

On the other hand, if you see the igniter glowing but still the gas won’t light up, the gas valve coils need replacement.

Defective Heating Element

The most vital component that helps a dryer work efficiently is the heating element. So, if a Samsung dryer is not heating, it is highly possible that the heating element has burned out. You can simply check the condition of this component with the help of a multimeter or visually inspect the issue.

So, if there’s actually a defect, you can clearly see a burned-out heating element. The only solution is to replace the heating element, but the process is very time-consuming and arduous.

Dryer Out of Gas

If the dryer is running out of gas, it won’t heat up. This is a pretty straightforward problem with a simple solution. All you need to do is pay your gas bills on time and regularly check the condition of the gas pipe to avoid any leakage problems.

Clogged Lint Trap

All types of dryers have a lint trap that captures all kinds of debris and fibers that fall from the clothes you put in. Then, if the lint trap is clogged, it prevents the air from entering the dryer and results in the Samsung moisture sensor dryer not heating.

Clogged Lint Trap

To avoid this problem, you must clean the lint trap after every use. Take the lint trap out and clean it thoroughly with the help of a vacuum cleaner or brush.

Broken Cycling Thermostat

The cycling thermostat controls the temperature inside the machine by turning the heater on and off. When it gets broken, it results in the Samsung front load dryer no heat.

In that case, you can use a multimeter and check the continuity to examine the condition of the thermostat. If there’s a lack of continuity, you need to replace the component.

Failed Control Board

The control board is basically behind every function of any heating device, and it’s pretty hard to check if it’s damaged or not. Hence, it is better to look for other external damages and obvious causes of why the Samsung dryer is not producing heat anymore.

However, if that’s the problem, it is better to call a technician and get this component fixed.


No machine can work efficiently if you push it to the limit. When Samsung dryers reach their maximum capacity, they’re not able to circulate the heated air sufficiently. As a result, the laundry at the bottom remains wet. 

Hence, you must only use 75% of the dryer’s space for your laundry to avoid overloading problems. In addition, it is better to split large loads into smaller ones to enhance the dryer’s functionality.

So, these are the most common reasons why a Samsung dryer fails to heat up along with the solutions. But what to do if it is behaving abruptly? You reset it!

How to Reset a Samsung Dryer?

Not producing heat is one thing; your Samsung dryer can even have starting issues, and it will have nothing to do with the damaged parts. In addition, electric glitches and power outages can also cause problems, and the dryer will behave abruptly. 

If that happens, the only and most effective solution is to reset it. And you can do it easily by following these steps:

  • Disconnect the dryer.
  • Wait for a bit (at least 5 minutes) until the wires are no longer electrically charged.
  • Plug it back in.
  • Press and hold the Start/Pause button on the remote for at least 15 seconds.

After that, your dryer will blink with no error code, which means it has been reset.

Conclusion – Maintenance is the Key

Dryers are a basic need for almost every home. It can surely be frustrating when yours is not heating up. With the solutions mentioned in this write-up, you can fix the problem yourself. However, you must take precautions when dealing with these issues. For example, you must turn off the power before making any adjustments or repairs.

Moreover, most of the problems can simply be avoided by proper maintenance. And, if there’s a need to replace the parts, you must only buy them from Samsung, as the third-party ones are not always compatible.
