Why My Samsung Dryer is not Heating?

One of the major reasons is a burnt-out heating component. Other common reasons include the insufficient power supply, defective or frayed cable, and blown-out thermal fuse.

Moreover, a defective thermistor or blocked ventilation can also lead to the issue of a Samsung moisture sensor or front load dryer, not heating. Some other reasons are the failed control board or defective motor.

We cannot point out the root cause immediately. First, we need to conduct some diagnostic tests and also need to check out different components.

Samsung Moisture Sensor Not Heating

1. Install Samsung Dryer Accurately

It can be an installation fault that leads to no heating at all. If your Samsung dryer is brand new and not heating, you should check the installation process.

Samsung electric dryers need a 240V power supply. So, make sure that you have connected it to the right power supply outlet.

Otherwise, your dryer motor and panel will work by the heater will not function. Furthermore, check the power cord, it should be plugged firmly into the wall outlet. Inspect the power cord for the signs of damage.

If you own a gas dryer, check the gas line connection and make sure the gas supply is constant and enough.

2. Clean the Ventilation and Lint Filter

One of the common reasons your Samsung dryer is not heating is the ventilation blockage. The dryer cannot receive proper air and overheats. Thus, it struggles to work and finally turns OFF.

So, check the lint screen whether it is empty or full. Next, clean the ventilation hose that connects to the back of the dryer. Also, remove the panel around the hose and clean every visible lint.

Similarly, you also need to clean the external vent that takes air from the dryer. You can check its proper functioning by feeling the airflow. The airflow should be consistent at the exit of the ventilation from the hose.

All the components of the ventilation can be cleaned out using the cleaning kit or the vacuum attachment. You should clean the lint filter before starting a new cycle.

3. Check Samsung Dryer Settings

Samsung dryers feature a lot of different settings. A new user may feel confused while using them. Some of the cycles run without heat.

For example, the ‘Echo Dry’ operates without heat in the beginning but heats up afterward. In some cases, the Echo Dry setting automatically applies to the ‘Normal’ and ‘Time Dry’ options.

So, you should check which setting you have applied and how it works. Kindly read the user manual of your Samsung dryer to understand everything clearly.

4. Conduct the Heat Test

You can diagnose the issue by conducting a heat test. The method is as follows;

  1. Set your Samsung dryer at ‘Time Dry’ and turn OFF the ‘Echo Dry’ settings.
  2. Start the cycle and wait for 30 seconds. Now, open the dryer door and feel the inside.
  3. Check whether it has hot air or produces a little heat. If you feel a little bit of heat, it means your dryer is fine.
  4. However, you may not feel any heat inside the dryer. In this case, turn the circuit breaker OFF for 30 seconds.
  5. Now, turn it ON and run a cycle on your dryer.

Most electric dryers have two circuits that are connected to each other. Usually, both trip together. But, sometimes, a single circuit will trip and your dryer will stop heating but will continue spinning.

5. Run A Vent Blockage Test

You can diagnose the real issue by running a vent blockage test on your Samsung moisture sensor or front load dryer. The process is as follows;

  1. Make sure your dryer is empty and its drum is cool.
  2. On the control panel, press the ‘Adjust Time Up’ and ‘Dry Level’ buttons at the same time. Release both buttons when the ‘Ins’ or ‘In’ appears on the display screen.
  3. If it does not yield any results, try another key combination.
  4. Press ‘Cycle 1’ or ‘Air Fluff’ together with the ‘Wrinkle Prevent’.
  5. Hold down the ‘Start/Pause’ to start the test. Avoid opening the door for 2 minutes or until the test is completed.
  6. The results will be displayed on the screen. Each code has its specific meaning and refers to a certain issue with the dryer. Here is a list of the codes and their meanings.

6. Examine the Exhaust Vent

Sometimes, the exhaust vent cannot provide proper ventilation. It happens due to wrong installation and usage. Your Samsung dryer will stop heating if the moisture and heat are not leaving the dryer.

So, you should ensure the following things regarding the exhaust vent;

  1. The vent should be properly sealed and fitted. There should be no gaps or air openings to allow the lint to accumulate.
  2. Use a good material for the exhaust vent instead of foil or plastic.
  3. It should be no longer than the maximum length. Do not change the direction without a necessity. Because every 90-degrees turn reduced the length by 6 feet.
  4. Kinks or flattening in the vent pipe can lead to lint accumulation. Your vent should be completely open throughout its entire length and not compressed.

7. Inspect the Heating Element

Both the Samsung moisture sensor and front load dryer work on the basis of the heating element. This component is responsible for heating up the dryer properly.

It is in the form of coils that can be damaged over the years. You can inspect it by the following method;

  1. Disconnect your Samsung dryer from the power source or cut off the gas supply and turn it OFF completely.
  2. The heating element is surrounded by a metal frame and connects to the heating element leads.
  3. Minutely inspect the heating element for any signs of damage or broken coil. If it is defective or broken, replacing it will solve the problem.
  4. You can confirm its proper functioning through a millimeter. Check whether it is receiving enough current and voltage or not.
  5. The reading should be around 10 Ohms. Moreover, the burnt-out heating element will give a bad smell and also have burnt marks.

8. Replace the Thermal Fuse

Samsung moisture sensors, as well as front load dryers, are equipped with a thermal fuse. It functions as a safety device and protects your machine from accidents such as catching fire.

The thermal fuse is blown when the dryer temperature exceeds a certain limit. It happens in the newer models of the Samsung dryer. While in older models, the dryer stops heating.

Overheating is usually caused by too much accumulated lint. So, this problem can be simply solved by replacing the blown-out thermal fuse. Follow these steps;

Unplug your Samsung dryer from the power outlet or cut off the gas supply.

  1. Confirm the location of the thermal fuse from the user manual of your specific model.
  2. You may need to remove the roller drum to access the fuse.
  3. Next, test the fuse using a multimeter to check the continuity.
  4. If it is blown, replace the fuse and your issue will be solved.

9. Check the Thermostat

A thermostat is responsible for controlling the heat in a dryer. While a thermistor works as a temperature sensor. Both elements work in collaboration with each other.

These two components may be located next to the heating element in your Samsung dryer. You can test them as follows;

  1. Locate the thermostat and thermistor in your Samsung moisture sensor or front load dryer.
  2. Use a multimeter to conduct the continuity test. Finally, replace the component that is faulty.
  3. A proper functioning thermostat produces 0.1-0.5 Ohms resistance.

10. Contact Samsung Service

I have included all the potential solutions in this guide. You should apply them all to fix your Samsung dryer. However, if nothing helps and you fail to diagnose the root cause then you must contact Samsung.

Explain to them your problem and request a repair. If your dryer is under warranty, you can get a free repair.
