Samsung Dryer Not Heating | 13 Issues with Solutions

Many people are having trouble drying their clothes because of a faulty dryer.

How frustrating is it to get home, put all your clothes in the dryer, and wait for what feels like forever, only to have nothing happen?

But even worse, when you take the clothes out, they’re still damp!

Check the element first if your dryer isn’t heating up. It is the most typical reason for a Samsung dryer not heating up.

Check the fuses, thermal cut-off switch, cycling thermostat, and board that controls the heater element next. Check the power supply as well.

So, we will get to the bottom of why Samsung Dryer is not heating properly and what’s causing your dryer not to heat. It might be something simple that you could easily fix yourself. 

Samsung Dryer Not Heating


Why is my Samsung dryer Not Heating?

Samsung dryers are high quality, easy to use, and last for a long time. But what happens when the dryer doesn’t heat? How do you fix it?

Check out the following step-by-step guide to repair your dryer that won’t heat.

1. Clogged Dryer Vent:

Clogged vents are probably the most common problem of a not heating dryer. So, before you do anything else, make sure your dryer vent is clear.

Here is how to fix it.

  • First, turn off the gas supply to your dryer.
  • Then, remove the screws that are holding the vent cover in place.
  • Next, disconnect the vent pipe from the dryer.
  • Finally, take a small amount of baking soda and water and pour it down the vent.
  • If you see bubbles, that means there’s a clog, and the baking soda is going to unclog it. If not, try again later.

2. Heat Sensor Problem:

A heat sensor failure can lead to your Samsung dryer not heating at all. If you notice that your dryer seems to work fine but isn’t heating your clothes, first thing first, check your heat sensor.

Here’s how:

  • Locate your dryer’s heat sensor. It’s usually a black plastic disc
  • Next, gently press down on the heat sensor.
  • Consequently, the sensor will be either fully or partially depressed.
  • If it’s partially depressed, that means there’s a problem. The sensor needs to be replaced.
  • If it’s fully depressing, then there’s nothing wrong with your dryer. Just run a load of laundry to air dry.

3. Defective Dryer Heating Element:

This can happen for a few different reasons. First off, make sure the element is fully inserted into the back of the dryer. If not, the element may be loose.

Also, check the wiring at the back of the dryer. It should be attached firmly to the wall with no visible cracks or damage.

In contrast, sometimes, the heating element itself is bad. You’ll have to replace everything in this scenario.

4. Insufficient Watts:

Make sure your circuit breaker isn’t set to a setting that’s too low. Most modern dryers have an auto-cutoff feature.

This way, the dryer will shut off if it stays on for a long period of time.

Meanwhile, your clothes continue to dry. If your dryer has an electronic thermostat, you can check the settings here.

You want to make sure it’s set to heat when at least 20 degrees Celsius outside.

Also, double-check the wattage of your dryer. Usually, you will find this information on the back of the dryer. However, you can also check the label on the back of your circuit breaker.

That number tells you the maximum watts that your dryer can use. Make sure that’s at least 100 watts

5. Dirty Dryer Lint Filter:

Dryer lint filters keep out most of the little bits of lint that get caught in your dryer vent.

Unfortunately, they also trap paper towels, hair, and other larger particles that can damage your dryer’s innards.

So, to clean the filter, run a cycle without any laundry.

On the whole, load set the dryer to the highest setting (usually heat). Then follow these steps:

  • First, locate your dryer’s lint filter. It’s usually a metal or plastic cover that screws into your dryer.
  • Next, completely remove the lint filter.
  • Finally, use a dryer vent brush to sweep out any remaining lint from the vent gently. That should do it!

6. Damaged Motor:

A damaged motor can prevent your Samsung dryer from heating. So, before you invest in a new motor, first check to see if it’s actually damaged.

Unplug your dryer and give it a little shake to do this. If you find something hard, it could be a component of the motor, and the motor is faulty.

A damaged motor also causes the Samsung dryer to make loud noises.

If not, you’ll most likely need to replace the motor.

Here is how:

  • First, turn off the power to the dryer.
  • Then, from the back of the dryer, remove the access panel.
  • Finally, remove one of the screws holding the motor in place.
  • Install the new motor after removing the old one.

Severe malfunction in motor can also result in the Samung dryer not starting problem.

7. Incorrectly Operated Dryer Timer:

Your dryer timer is an easy way to program your cycle to start and stop automatically.

That way, you don’t have to worry about forgetting to set the clock or getting distracted and leaving the laundry in for too long.

The thing is, your dryer timer doesn’t always work properly. But you can easily fix it. Here’s how:

  • First, turn off your dryer.
  • Next, find the two screws holding the back of your dryer timer in place.
  • Then, remove the back of your timer.
  • Finally, clean out any lint that might be stuck in the timer. That’s all there is to it.

8. Dryer Door Not Opening Or Closing:

This is an easy problem to fix.

First, check to see if your belt is hooked up correctly. Make sure the black and white wires are connected to the top and bottom of your dryer’s drum.

If not, your dryer’s sensor may be malfunctioning, and your dryer won’t heat properly.

It is certainly possible that the sensor is just old and needs replacement with a new one.

Also, double-check that your dryer’s door isn’t blocked. The door may be unable to open or close as a result of this. 

Besides checking your belt, you can also try opening and closing the door manually to make sure it isn’t stuck.

9. Damaged Dryer Vent Pipe:

Damaged vent pipes can also lead to your Samsung dryer, not heating. Unfortunately, this is not an easy fix.

To get the vent pipe fixed, you’ll need to remove it and take it to a repair shop. Here’s how:

  • First, locate the damaged area of the vent pipe. It should be a straight line where the rubber meets the metal.
  • Then, unscrew the screws that hold the vent in place.
  • Finally, gently pull the vent out of the wall. Be careful not to yank on the pipe.

Your dryer vent pipe is what connects your dryer to the outside world. Unfortunately, it’s also a common source of house fires. So, it is important to keep an eye on it for cracks or leaks.

If you find something suspicious, have a professional take a look.

How do you know if your dryer vent is leaking? Well, if you smell gas, it’s probably time to replace your dryer vent pipe.

Replacing your dryer vent pipe can be tricky and expensive.

10. Damaged Dryer Vent Assembly:

It is also possible that your dryer won’t heat up correctly as a result of this. If this occurs, the complete dryer vent assembly will need to be replaced.

That way, any potential damage from a leak can be fixed at the source. Here’s how:

  • First, locate the dryer vent assembly on the inside of your wall. It will have two screws that hold it in place.
  • Then, unscrew these screws and remove the old vent assembly.
  • Finally, install the new one.

11. Test the Thermostat: 

Most Samsung dryers have two thermostats: one for the top and one for the bottom of the drum.

Make sure both are set to high. When you set the temperature, you press the green button.

When you want the dryer to stop, you press the red button. And somewhere in between, you can adjust the temperature using the slider.

So, the first thing you will want to do is make sure the red and green buttons work. If not, it could be a defective unit.

If so, you can order a replacement from Samsung. You also want to make sure that the slider moves when you press it.

Test your thermostat first if you suspect it isn’t working properly. Here’s how:

  • Turn your heat up to high.
  • Then, turn it back down. And note the temperature where you turn the heat back down.
  • The lower that number, the better your thermostat is at regulating the temperature.

If your dryer runs fine with the old thermostat but gets hot with the new one, then there’s no reason to replace the entire thing. Just replace the thermostat.

12. Check The Socket Fuse:

Dryers have a built-in electrical fuse to protect the electronic components inside from overheating.

Remove the access panel on the rear of your dryer to check this fuse. Then, locate the black fuse underneath the dryer.

It should be about 1/8th of an inch wide and anywhere from 3/16ths to ½ an inch long. If it’s too small, replace it. If it’s too large, wait a few weeks and try again.

13. Control Board Heater Relay Failed:

Your dryer has two heaters: one for the top and one for the bottom of the drum.

When you turn on your dryer, these heaters kick in. And they automatically shut off when the drum is full.

Sometimes, a failed heater relay can lead to your dryer not heating up properly. Replace the faulty part if this is the case.

Why Does My Samsung Dryer Heating Element Keep Going Out?

If your Samsung dryer’s heating element keeps going out, there may be a few different reasons why this is happening.

There can be an issue with the thermostat, there could be a loose connection in the power cord, or it could be that something is wrong with the heating element itself.

In order to know what is causing your heating element to go out, you’ll need to do some troubleshooting on your own.

The most common causes of heating element failure are dryer venting, loading, and temperature control.

  • Check your venting by looking for a lint nest in the area of the dryer. Try vacuuming the area if you don’t see anything in there.
  • Load your clothes in a way that they are not overlapping or crammed together inside the drum. Your clothes should also be evenly distributed around the drum perimeter to avoid uneven heating. It is best to use light clothing loads when trying to keep your dryer running longer.
  • To maintain proper drying temperatures, selecting an appropriate cycle for your load size and type of fabric being dried is important, including setting an appropriate drying temperature on your machine. You can do this through trial and error by checking for wet spots during drying or using a “Fabric Condition” setting on your machine. If you notice that your dryer has a lot of “lint pops,” this is an indication that there is a vent blockage. You can either clear out the lint yourself or hire an expert to do it for you.

Samsung Dryer HE Code Reset

When the Samsung Dryer HE Code is not working, it can be very difficult to figure out the problem.

There are a number of different reasons why your Samsung Dryer HE Code may not be working, and they all require different troubleshooting steps.

To reset your Samsung HE Code Dryer, locate and push in/turn off the button for 5 seconds until ‘CLEAR’ appears on the screen.

Release the button, then press the start or cancel button. Your Samsung dryer should be good to go. 

The following are some of the most common issues that can cause your Samsung Dryer HE Code to stop working:

1. Damaged control board

A failed or damaged control board can prevent the dryer from heating up. To fix this, you’ll need to replace the entire board (this is usually an easy fix).

2. Low or high water level

A full or partially empty drum can prevent your dryer from heating up. You should see the owner’s handbook for further information about this.

Worn or damaged belt – Worn or damaged dryer belts can cause missed or erratic heat cycles. You will need to replace the belt.

3. Failed motor

A failed motor can cause your dryer to stop spinning.

In most cases, you can easily replace the motor yourself (however, some models have a hard drive inside the motor that needs to be replaced).

4. Facility with low voltage

Low voltage can be caused by a number of different things, from a tripped circuit breaker to a bad connection.

To troubleshoot, turn off your dryer, unplug it, and plug it back in. If it powers on, then it’s a wiring issue. If not, then you likely have a low-voltage problem.

5. Bad contact

A bad contact can prevent your dryer from getting power. In many cases, a dirty contact will clear itself after a few days.

However, if this happens repeatedly, you’ll need to replace the contact.
