What Is Samsung Dryer Vent Sensor?

The Samsung dryer vent sensor is a safety feature that is designed to detect when the vent in the dryer is clogged or obstructed.

When the sensor detects that the vent is indeed blocked, an error code will be displayed and prevent the dryer from running to avoid overheating and potential fires.

The error code can be cleared by cleaning the vent and ensuring that it is properly connected and free of any obstructions. Some Samsung dryer models also equipped with smart technology can also alert you to a clogged vent via the smartphone app or through a notification.

How Samsung Dryer works?

Listed below are the parts that make your Samsung dryer vent work so you have a good idea on each of these.

Samsung Dryer Vent Hose

A dryer vent hose, also known as a dryer exhaust hose or dryer vent duct, is a flexible tube that connects the dryer to an outside vent in order to allow the hot air and moisture produced during the drying process to be safely released to the outside of a building.

Normally, dryer vent hose have a diameter of 4 inches and are usually made of plastic or aluminum. It is important to make sure that the dryer vent hose is properly installed and maintained to prevent fire hazards and to ensure the efficient operation of the dryer.

Samsung Dryer Vent Thermostat

A dryer vent thermostat is a safety device that is installed in a clothes dryer vent system to monitor the temperature of the exhaust air. It is designed to prevent the dryer from overheating and causing a fire. If the thermostat detects that the exhaust air temperature has exceeded a pre-determined safe limit, it will shut off the dryer to prevent a fire hazard.

Samsung dryers are equipped with thermal fuses and high limit thermostats that are designed to prevent overheating of the dryer. If one of these devices fails, the dryer may shut off and a code will be displayed on the control panel.

Specific models can have different ways of protecting or describing the different devices, so it’s best to consult your specific model manual to know the details.

Samsung Dryer Vent Filters

Samsung dryer vent filters are filters that are used in Samsung dryer machines to remove lint and other debris from the exhaust air before it is vented outside. They are mostly located either in the dryer cabinet or in the exhaust duct.

It is important to regularly clean or replace these filters to maintain the efficiency and safety of the dryer. Not replacing them can cause the dryer to work harder and increase the risk of fire hazard.

Samsung Vent Moisture Sensor

A Samsung vent moisture sensor is a device designed to detect moisture in the air vent of a Samsung air conditioner or dehumidifier. It helps to prevent mold and mildew buildup by alerting the user when the air in the vent is too humid.

The sensor typically works by measuring the humidity level in the air and sending a signal to the air conditioner or dehumidifier’s control panel, which then adjusts the unit’s settings to reduce the moisture level. Some Samsung vent moisture sensors also include a built-in alarm that sounds when the humidity level becomes too high.

Samsung Dryer Vent Issues

There are several reasons why a Samsung dryer vent may not be working properly. Some of the most common causes include:

Clogged vent: The dryer’s vent can become clogged with lint and other debris, which can restrict air flow and prevent the dryer from venting properly.

Damaged vent hose: The vent hose that connects the dryer to the wall vent can become damaged or disconnected, which can also prevent the dryer from venting properly.

Obstructed vent: The wall vent on the outside of the house can become obstructed by debris, such as leaves or a bird’s nest, which can restrict the flow of air and prevent the dryer from venting properly.

Malfunctioning Thermostat: Thermostat can be malfunctioning and not triggering the dryer to shut off when it reaches the desired temperature, which leads the dryer to overheat and shut off.

Blocked air filter: If the air filter is blocked it could decrease the airflow and affect the drying performance.

Faulty Dryer drum seal: If the dryer drum seal is damaged or faulty it can cause the dryer to overheat and shut off.

Depending on your Samsung dryer vent’s make and model, it still is recommended to check the owner’s manual for troubleshooting steps and guidance or contact Samsung for assistance.

Samsung Dryer Vent Sensor Reset (Step by Step)

To Reset the Samsung Dryer:

Step 1: Unplug the Samsung dryer from the power source or turn off the circuit breakers. If your Samsung dryer is connected to more than one circuit breaker, ensure that all of them are turned off

Step 2: You can test to make sure the dryer is fully disconnected from the power. To check, open the door and check for the dryer light. You can also push the buttons on the control panel to make sure they’re unresponsive.

Step 3: Leave the dryer disconnected for 5 to 10 minutes to allow the electrical charge clear out of the dryer. During this time, the dryer will reset the memory, sensor, and any other controls that have been established.

Step 4: Once the time elapses, reestablish power to the Samsung dryer by plugging the dryer cord in or turning back on the circuit breakers. Wait till the dryer restarts. With that, the dryer is completely reset.

Step 5: While resetting the Samsung dryer vent sensor is the first thing that comes to mind when experiencing heating problems, it is not always the solution. If you notice any temperature or heating error codes on your Samsung dryer which are related to the vent sensor, resetting the dryer will clear the error codes. However, it will not solve the problem. In this case, you would have to look for the reason behind the error code.

How to Run a Vent Blockage Test

Error codes that have to deal with the vent usually signal a vent blockage issue.

A vent blockage issue signifies that the vent is clogged. You can confirm this by running a vent blockage test. To run the test;

  • Ensure that it is empty before you close the door. Removing laundry from the drum will improve your chances of getting accurate results.
  • Press “POWER” to turn the dryer on and wait for about 5 seconds, then press and hold “Adjust Time Up + Dry Level until Ins or In appears on display. This combination might not work on some modes. If it doesn’t work, try “Ccyle 1 + Wrinkle Prevent” or “Air Fluff + Wrinkle Prevent”
  • The next step is to press and hold START/PAUSE to start the Vent Blockage test. This test has a run time of about 2 minutes. Do not open the door during the test.
  • When the test is complete, the results will be displayed.

The results could be:

  • 0 or End: The duck system is normal and unblocked.
  • Clg, Cg – This indicates that the vent is clogged.
  • C80, C8 – This indicates that about 80% of the vent is clogged.
  • C90, C9 – This indicates that over 90% of the vent is clogged.
  • C1, CL1 – This indicates that laundry is detected inside the drum.
  • Ct – This indicates that the dryer is below freezing or above 104°F

Not all models allow for a vent blockage test. Fortunately, there are other ways to test if the vent is blockage and the cause of the low heat issue. In models without the vent blockage test, you will have to disconnect the vent and check the dryer’s heater performance.

To get started:

  • Disconnect the exhaust vent from the dryer
  • You will have to run a Time Dry Cycle for at least 30 seconds (turn off the Eco Dry settings, if your model has any)
  • With your hand, feel for hot air inside the drum
  • If the dryer feels hotter when the vent is disconnected, it means the vent need cleaning to get rid of the debris causing the clog. If you fixed the vent previously check if it meets the requirements set in the user manual.
  • However, if you feel the same amount of air with the vent disconnected. It means the vent is not the cause of the low heat issue.
  • If you conclude that the vent is clogged, you would have to clean. Hire a technician to clean the vent properly.

How To Reset Samsung Dryer Heating Element

The dryer heating element might not be unconnected to the issues you’re having with the dryer vent. You might want to reset the heating element to check if it solves the problem.

You can reset the Samsung dryer heating element by resetting the entire dryer. To do this, you need to unplug it and plug it back in again. Ensure that you give enough time between both stages. When unplugged, turn off the circuit breaker and wait for about 10 minutes for any electrical current left in the dryer to be dissipate.

After plugging it back in, check if the dryer heating element is working as it should. If not, then you need to contact a technician. In some cases, the heating element in your Samsung dryer may need replacing. A technician should be able to confirm if the heating element if faulty.

How to Perform a Network Reset

A network reset will erase all Wi-Fi and network information from the dryer. A network reset can only be done if your dryer has Wi-Fi capability. To perform a network reset, follow the steps below

  • Hold Smart Control until AP displays (this should take about 3 seconds).
  • Hold Temp until OK displays (this should take about 7 seconds). The display will go back to AP after this.
  • Turn off the dryer.

Wrapping Up

Resetting the Samsung Dryer Vent Sensor can help in cases where the Samsung dryer fails to work or overheat. You might also want to check if there is any error code associated with the Samsung dryer. Error codes will provide a better diagnosis of the issue with the dryer so you can take the right steps to fix them.


A dryer vent is a duct or a pipe that is used to exhaust the hot, moist air produced by a clothes dryer to the outside of a building. The vent helps to prevent the buildup of lint and other debris inside the dryer, which can be a fire hazard, and also helps to reduce the amount of moisture inside the home, which can lead to mold and mildew growth. In most cases, a dryer vent is made of metal and is connected to the back or side of the dryer, running through the wall and going to the outside of the building. It is important to keep your Samsung dryer vent dryer clean, well-maintained and unobstructed to ensure proper function and safety.
