Why is Your Samsung Dryer Not Working and Drying the Clothes?

Dryers are among the most useful appliances in the home. Once they stop working, though, they are rendered redundant until you fix the underlying faults. While the Samsung brand is widely accepted as one of the most reliable for long-term usage, they are still vulnerable to wear and tear. Left untreated, clothes will be left wet and smelling. Before considering a replacement, though, you should know that a variety of quick-fix dryer repair services may correct the damage. This guide will help you with most Samsung models, including:

Symptoms of a Samsung Dryer Not Working as it Should

Is your Samsung dryer taking too long to dry clothes despite the fact it powers up and runs a cycle? The following symptoms are likely to occur:

  • Dryer not heating.
  • Dryer drum not turning.
  • Dryer has a burning smell.
  • Odd operational sounds.
  • Clothes feel wet or smell.

Check the Error Code

If your Samsung Dryer is not working due to a mechanical fault, the on-board computer should detect it and inform you of the problem by displaying the error code. If this happens, your first step is to check it in the manual or via Samsung’s help center. This will provide clarity as to the severity of the issue and whether you need to call a professional repair service.

Test for a Vent Blockage

Most of the newer Samsung dryers boast blockage test capabilities from the control panel. If yours does, you should run the test before checking any other elements:

If a blockage is found, this is the chief reason for a lack of warmth. Clean the outside hood and the inner exhaust vent before running the test once more. If the new test shows a problem, finding a replacement vent that corresponds to your model should correct the issue.

If your Samsung dryer does not include this feature, you can disconnect the vent manually before running a cycle for one minute. Then open the drum to see if it feels hotter than it did before, you will need to thoroughly clean the vent before reattaching it.

Test Tripped Circuit Breakers

Like many brands, electric Samsung dryers have two breakers. While they should be connected in a way that means they’ll trip simultaneously, it is possible for only one of them to break. When this happens, the dryer will spin without producing heat.

You can complete a manual reset by turning the circuit off for one minute before switching it back on. Following this, start a cycle for 30 seconds on Time Dry before opening the door and putting your hand inside. If you can feel a little heat, your problem should be fixed.

Check The Socket Fuse

It’s very unlikely but if you’ve changed the plug and do not have enough voltage, the Samsung dryer won’t run properly. The heating function will naturally be the first to suffer should this occur. It’s not an applicable issue to many people, but it could be the source of problems in a small number of cases.

Change the Mode Settings

When running a cycle with a combination of heavy and light materials, the Mixed Load Bell/Damp Alert setting (depending on the age of your Samsung dryer) is designed to combat the issues caused by lighter items drying more quickly. Turn it on, and you’ll receive a notification when the load hits 80%. This enables you to remove the dry items and allow the final pieces to dry normally.

Similarly, when using a Sensor Dry cycle without gaining the desired results, simply increase the setting to a higher Dry Level and you should notice a significant improvement.

Check the Moisture Sensors

The moisture sensors are two bars inside the Samsung dryer that are usually found in the lint filter housing. They serve to detect wet clothes inside the cycle, which will tell the dryer to initiate or maintain the drying cycle. So, if they are obstructed by residue, the machine may not heat or will turn off the heat prematurely. Cleaning the sensors with a little soap and a soft cloth may fix the issue.

Overfilling the dryer is naturally problematic and can prevent clothes from drying. However, an overly small load will also result in the dryer not heating because the moisture sensors will not detect enough damp clothes to switch the heating elements on. Either wait until the load is bigger, or add a couple of wet towels to combat the issue.

Check the Lint Filter & Drainage

While checking the drum, the lint filter should be changed. This is where the majority of moisture will collect, and too much of it will prevent the machine from working properly as the moisture won’t be able to leave the dryer. The lint filter should ideally be changed after every cycle to avoid accumulated moisture.

Similarly, the drainage should be checked. If the Samsung model has a drainage hose, you must check that it is installed properly and not submerged by water. Meanwhile, internal water tanks should be changed every 1-2 cycles.

Test the Thermostat

A faulty thermostat will stop the dryer from receiving enough hot air to adequately dry the clothes. Using a multimeter will allow you to test the performance of the thermostat and determine whether a replacement thermostat is required when your Samsung model is not working.

Overheating can cause the heating fuse to become faulty, which will result in a spinning drum without heat. The multimeter test will determine problems with this part of the dryer’s heating mechanisms too.

Check the Heating Element

If the dryer has a burning smell, the heating element may be burnt out. Poor maintenance will encourage this to happen far sooner. The heating element is usually found behind the front panel. Turn off the machine and access it by removing the control panel and front panel. A visual inspection should quickly confirm your suspicions. 

When it is damaged, it’s vital that you respond quickly by replacing it as to avoid escalating damage and possible health hazards. The Samsung heating element can usually be replaced for under $100 (often nearer $50) and changed on a DIY basis.

Now, one of the common causes of poor drying performance when it comes to your Samsung dryer is a bad dryer moisture sensor – it typically causes the dryer to stop too early (with your clothes still damp).

And often the solution is replacing the part – though you can try to clean it first since sometimes issues occur due to accumulated lint crap.

But here is the thing: if cleaning it does not help and you are considering swapping out the moisture sensor, you will want to be sure that it is actually bad.

And that’s where a Samsung dryer moisture sensor test comes in.

So, how do you test the moisture sensor?

Read on to learn how to perform Samsung dryer moisture sensor test (step-by-step).

Samsung dryer moisture sensor test (How to tell if the sensors are bad)

So, how do you know when a moisture sensor is bad?

Now, there is a basic test that can help you verify if a dryer moisture sensor is working or not.

And the good news is that the test is pretty simple…it’s more of a visual test rather than something technical like doing a continuity check.

So here is how I usually tell if a sensor has gone out..

The sensor bars (remember there are typically two moisture sensor bars in your dryer) can usually get caught on something and ripped out.

They can also get a bit of lint coating on them over time (if this is what I’m seeing I first try to clean them and I only get new ones if cleaning does not get the dryer to begin drying clothes fine again).

In short, I do a visual inspection of the two bars (of course, each looks like a piece of metal) and look for signs that it could be damaged.

But as I have told you above, you might notice other things… it could even turn out that there is an old dryer sheet that is stuck to the sensor bars, causing the dryer to malfunction.

And here you only need to remove the sheet to have it work again.

Now, if everything else appears okay, you probably have a faulty moisture sensor.

Quick Note: Try using the timed dry rather than sensor dry settings and see if the dryer will work- if so, then that can be another sign that the sensor is having serious issues.

Samsung dryer moisture sensor test – an alternative way of  testing the sensor bars

Turn the dryer on then set it to “normal press” and hold  the Mixed Load Bell + Temp for about 3 seconds.

Your dryer should give a beep sound. Once it does that, press and hold onto the “Temp” and “Time” button simultaneously for approx. 6 seconds. The display should now say 0.

Next open the door then put your hand right over the moisture sensor bar- the display should go up to 1. You then take it off. Now it should go back to 0,.

In a nutshell, it should keep switching between 0 and 1 when you place your hand off/on the unit.

So, when are the bars faulty?

If the display is not changing to 1, then try to clean the bars.

You may also want to check the sensor bars connection(it can be  disconnected or loose).

Don’t forget the sensor bars usually connect to their own plug (this goes to another plug -at the  side of the dryer drum- then goes back to the main control board).

If all that looks good, make sure the vent/exhaust going outside is completely clear as well.


A word about cleaning the moisture sensor

If your dryer stops after a few minutes or seconds, you most likely have a dirty moisture sensor.

So, how do you fix this?

Well, your best bet is to clean the moisture sensor.

In the following section, we will look at how you do this.


Samsung dryer moisture sensor location

In Samsung dryers, the moisture sensor is, for the most part, located at the front of your dryer drum on the filter housing.


Samsung dryer moisture sensor cleaning -How to clean Samsung dryer moisture sensor

Here’s how to access and clean the bars.

  1. Turn off your dryer and unplug from the power outlet.
  2. Open the dryer’s door and remove the lint filter.
  3. Remove the screws securing the lint filter housing.
  4. Lift up the housing and disconnect the wires attached to the housing.
  5. Fully remove the housing and look for two parallel and similar bars that look like the ones below.


  1. Using a small screwdriver, ply out the sensors.
  2. To clean the sensors, rub some mild soap on the bars and clean well with a slightly dump piece of cloth. While at this, you should also take the time to clean your lint filter.
  3. Put back the moisture sensors and reconnect the wires.
  4. Screw back the lint filter housing and insert your lint filter.
  5. Finally, plug in your dryer and see if this fixes it.


When to replace the moisture sensor bars

Needless to say, if cleaning does not fix your dryer, you should consider replacing the moisture sensor.

With that in mind, we recommend the genuine OEM Samsung moisture sensor for dryers.

Note that this part is sold as one so if you want to replace both sensor bars, make sure to order 2 of them.

Additional installation instructions

When installing sensor bars, simply follow the steps above all the way to step 7.

Then in step 8, swap the old sensors with the new sensors.

You will find it quite easy – it should take you around 5 to 10 minutes.


What else can you try if changing out the sensors does not work?

De-activate “Wrinkle Prevent” button

If you have replaced the sensor bars and the dryer still won’t stop acting up, check if the Wrinkle Prevent button could be depressed.

You see, when the “Wrinkle Prevent” option is activated (pressed ON), it will extend the cycle by 90 minutes.

And that can make your dryer not to end the dry cycle automatically when it has finished drying clothes.

So you may want to check and then turn off the Wrinkle Prevent Button (if it is ON).


Samsung dryer moisture sensor test – Frequently Asked Questions [FAQs]

Can you use a dryer without moisture sensor?

Well, it is not recommended and I believe your dryer could throw an error code if no moisture sensor is installed.

In fact, the sensor dry function won’t work correctly if the sensors are not connected(there will be no way of telling the timer that clothes are not dry when you put them in).

In other words, it would be in your best interest to try cleaning or replacing the sensor.


Can a bad moisture sensor cause the dryer to start running for a few seconds then stop then start again?

No, that is not a common moisture sensor problem though it makes sense to try cleaning the 2 metal sensors- you can do that with a dish wash sponge(the rough side) and see if it will do the trick.

Dryer Residual Moisture Sensor

Dryer Residual Moisture Sensor is an expensive option.

Let’s see if it’s needed or not.

How do dryers “understand” how damp the laundry is in the drum? Overview of residual moisture control systems in dryers.

To dry delicate garments, you need to know the moisture content of the laundry in the tumble dryer – this allows you not to overdry the garments and maintain the integrity of the fibers.

Hotel terry towels are dried using a residual moisture sensor to ensure that the towels are soft and fluffy to the touch.

How do dryers determine the moisture value in the drum? Modern manufacturers of professional laundry equipment use entire systems in their work. The residual moisture control system consists of sensors and devices for analyzing sensor readings.

Conductometric moisture measurement

There is a metal strip around the back of the drum. A graphite brush slides along this strip, creating a sliding contact. There is another pair of brushes and a graphite ring on the shaft near the bearing assembly. These two sliding contacts are energized. Since there was rather damp laundry in the drum at first, the discharge time in the drum is shorter than in the drum with dry laundry. The residual moisture control system determines the electrical conductivity of the interelectrode gap depending on the humidity. The control panel analyzes the incoming information and displays the information received in a user-friendly form, and also uses the information received to work on the program. When the set humidity level in the drum is reached, the program ends if the program was up to the specified humidity.

A – contact surface on the outside of the tumble dryer

Piezometric moisture measurement systems are installed in top five quality equipment – leading European brands and equipment from the USA.

Analytical humidity measurement

A temperature sensor is installed at the outlet of the hot humid air duct. This sensor measures the temperature of the outgoing air and sends the information to the control unit. The control unit analyzes and compares the temperature of the air entering the drum and the temperature at the outlet. The control unit has a built-in relationship between humidity and air temperature. When a certain temperature is reached on the sensor, the unit sends a command to end the drying program, as if a certain humidity has been reached.

This method of measuring moisture in dryers is the most common and popular due to its low cost and simplicity. However, this method does not shine with accuracy.

Infrared moisture measurement

The most accurate and most expensive way to measure residual moisture in a tumble dryer. Different manufacturers use their own developments for infrared moisture measurement. Someone measures the temperature using infrared radiation and then analyzes the data in the control panel according to the dependence, as is the case with the analytical method.

Someone compares the infrared flux with a calibration curve. The accuracy of the infrared measurement makes it possible to measure humidity up to 3%.

Infrared moisture measurement is often found in Kannegiesser tumble dryers used for drying and shaking laundry downstream of a dewatering press in a washing line.

Whichever way you choose to monitor the moisture content of the laundry in the tumble dryer, it is important to remember that the Residual Moisture Sensor is needed to:

  • drying terry towels and bathrobes
  • drying down jackets
  • dryers for delicate fabrics
  • wool drying

Residual moisture measurement systems in tumble dryers also save energy. The tumble dryer turns off heat and power consumption when the clothes in the drum are dry.

Residual moisture sensor – option for dryer, along with drum reversal and drum material. In the Electrolux tumble dryer example, the residual moisture sensor changes the PNC of the machine and affects the price and production time.

The following causes that occur when the dryer does not stop are listed from most likely to least likely. Check or test each cause, starting with the most likely causes.

Cause 1 Airflow problem

If the vent is clogged or partially clogged, it will restrict the airflow through the dryer, significantly increasing drying time. To ensure proper dryer performance, you must clean the dryer ventilation system at least once a year.

Cause 2 Impeller

The impeller works with a drive motor to supply air to the tumble dryer. Lint, socks and small items of clothing can escape from the lint screen and enter the impeller. In addition, the impeller sleeve may wear out, allowing it to become loose on the motor shaft. If something is blocking the impeller or if the impeller is damaged, it may take too long to dry the clothes. To determine if the impeller is working properly, open the vent and check the air flow. If the air flow is weak, check the impeller for obstructions. If there are no obstacles, then try to manually rotate the impeller and if it dangles, then replace it.

Cause 3 Gas valve solenoid

Gas dryers have two or more solenoid valve coils. The gas valve solenoids open the gas valve to allow gas to enter the burner block. If the solenoid fails, the burner may operate intermittently. If the burner continues to turn off, the dryer is not heating up enough and may not stop. To determine if one or more of the gas valve solenoids has failed, check the igniter. If the igniter glows and goes out, but does not ignite the gas, then the gas valve solenoid is faulty. If one or more gas valve coils are faulty, we recommend replacing all of them as a set.

Cause 4 Heating element

The heating element (heater) heats the air before it enters the tumble dryer. Over time, the heating element may burn out. If the heating element does not work, the clothes will dry much longer. To determine if a heating element is burned out, use a multimeter to test it for continuity and if not, replace it.

Cause 5 Heating element unit

The heating element (heater) heats the air before it enters the tumble dryer. Over time, the heating element may burn out. If the heater block does not work, the clothes will dry much longer. To determine if a heating element is burned out, use a multimeter to test it for continuity and if not, replace it.

Cause 6 Lint filter

The lint filter may be clogged. Dryer sheets and fabric softener can leave residue on the lint filter, reducing airflow. If the fluff filter is clogged, clean it.

Cause 7 Humidity sensor

The humidity sensor monitors the moisture level of the clothes and sends a signal to the control panel when the clothes are dry. If the humidity sensor is not working properly, it may erroneously signal that the clothes are still damp, causing the dryer to keep running even though the clothes are dry. However, this rarely happens. Before replacing the humidity sensor, check for increasingly broken parts. If you have determined that all other components are working correctly, then replace the humidity sensor.

Cause 8 Cycle thermostat

Cycle thermostat cycles the heating on and off to control the air temperature. If the thermostat is defective, the dryer will not heat up. However, this is rare. Before replacing the thermostat, check the increasingly broken parts. If you have determined that all other components are working correctly, then check the thermostat with a multimeter for continuity and if it is broken, then replace it.

Cause 9 High limit thermostat

The high limit thermostat controls the temperature of the dryer and turns off the burner if the dryer overheats. If the high limit thermostat is faulty, it may turn off the burner even if the dryer is not overheating. However, this is rare. Before replacing the high limit thermostat, check for increasingly broken parts. If you have determined that all other components are working properly, then check the thermostat with a multimeter for continuity and if it is broken, then replace it.

Cause 10 Thermistor

If the dryer does not stop, the thermistor may be defective. Some dryer models have a thermistor that is used to control the temperature of the dryer and turn the heat on and off. If the thermistor is defective, it is possible that it can turn off the heat too soon, significantly prolonging the drying time. However, this is rare.

Cause 11 Timer

Mechanical timers have a watch-like winding mechanism that rotates the timer down to the off position on the control panel. If the clock is not running on the timer, it will not turn off at the end of the drying cycle and the dryer will continue to work.
