In this article, we’re going to take a deep dive into some of the most likely reasons why your dryer isn’t heating up. Then, we’ll explore a few frequently asked questions on this topic.
TLDR: if your Samsung dryer fails to generate heat, it is predominantly attributed to a burnt heating element, accounting for 80% of the cases, while the remaining 18% are caused by a blown thermal cut-off fuse, cycling thermostat, or a failed control board heater relay. The remaining 2% may stem from an inadequate power supply, whereby the dryer receives only 110 Volts, instead of the required 240 Volts.
Detailed analysis of potential causes
Burnt Heating Element
What it is: For your Samsung dryer to effectively dry your clothes, it must first generate heat. That’s where the heating element comes into play.
The precise design of the heating element can differ based on the model that you have. Still, they all generally work the same way.
When the machine needs heat, it sends power to the heating element. The heating element generates heat, which is then pushed into the dryer by a blower fan.
That hot, moving air removes moisture and dries out anything that you placed in your Samsung dryer.
Why it fails: Whenever a Samsung dryer isn’t heating up, there’s an 80% chance that it’s caused by a heating element that has burned out.
You can confirm whether or not that’s the case by inspecting the heating element on your Samsung dryer, either with a multimeter or visually.
When you use a multimeter to check the heating element’s resistance, the reading should be approximately 10 Ohms. If that’s the case, then that means your heating element is in good working order.
Besides that, you can grab a flashlight and inspect the entire heating element up-close.
Burnt out elements will give off a burnt smell or have burn marks somewhere along the length of the element.
How to fix: To fix this problem, you’ll need to replace the heating element. Doing that is pretty straightforward.
However, reaching the heating element housing is what makes this a time-consuming and labour-intensive repair job.
Always begin any repairs by shutting off the power supply to the dryer to prevent injury and electrocution.
Then, keep your user manual and technical sheet close by as a quick reference. That will help you locate and identify the heating element on your model, which will be in its housing somewhere along the air vents.
To get there, you may need to remove several parts that include the drum and any other components in the way.
Once you’ve reached the housing, however, you’ll need to remove the existing heating element and disconnect the electrical connectors attached to it.
Fix the replacement in the same way, then work your way backwards by replacing any components and panels you took apart earlier.
Burnt Thermal Cut-Off Fuse
What it is: When it comes to home appliances that generate heat (e.g. your stove, or in this case, your Samsung dryer), there’s an extra component that adds protection from overheating.
That part is called the thermal cut-off fuse. They’re known as a ‘sacrificial’ device because they burn or blow out to protect the rest of the appliance.
In this case, your Samsung dryer has a thermal cut-off fuse at the heater assembly that protects against overheating.
If temperatures rise too high, the thermal cut-off fuse will burn out and prevent the dryer from heating up.
Why it fails: When a Samsung dryer isn’t heating up, there’s a 10% chance that it’s because of a burnt thermal cut-off fuse in the heater assembly.
As mentioned before, this happens whenever the temperature around the heater assembly rises beyond safe levels, as the fuse burns out to protect the rest of the machine from damage.
That kind of overheating typically happens because the dryer’s vents are clogged.
Without proper airflow to carry heat away from the heating elements, the heater assembly overheats and leads to the thermal cut-off fuse burning.
How to fix: There are two parts to fixing this problem. Firstly, you’ll need to replace the burnt-out thermal cut-off fuse.
These are ‘disposable’ parts in the sense that they can’t be repaired. They can only be replaced.
As usual, shut off the power supply before performing any repairs. Plus, keep your user manual and technical sheet nearby as a quick reference.
That will guide you as you remove the necessary panels (typically the back panel) to access the heater assembly.
Here, you must be cautious of one other thing: if the heater assembly is still hot, do not work on it until it has cooled down completely.
Then, disconnect the burnt fuse and replace it with the new one.
Replacing the fuse only solves the symptom and not the root cause. Be sure to clean out all of the dryer’s vents to ensure proper airflow and prevent overheating.
Cycling Thermostat Failed
What it is: Your Samsung dryer isn’t generating heat continuously until the end of the drying cycle.
Instead, it only generates heat until it reaches its set temperature before shutting off the heater.
When the temperature is too low, then it’ll repeat the heating process as many times as necessary to maintain the right level of heat throughout the cycle.
To ensure that the heater turns on and off only when appropriate, your dryer relies on a cycling thermostat.
It senses when the temperatures get too low or too high and reacts accordingly.
Why it fails: The cycling thermostat is continuously in use and might fail over time.
When that happens, it might not sense that the temperature inside the dryer is too low, and therefore fails to turn on the heater.
If you’ve been using your Samsung dryer for a long time now, then it’s possible that the thermostat has suffered from too much wear and tear and cannot function correctly.
You can diagnose the cycling thermostat with your multimeter by checking its resistance.
A functioning thermostat should produce a reading of 0.1-0.5 Ohms. However, it’ll show an infinite reading if it’s faulty and needs to be replaced.
How to fix: Typically, you can find the cycling thermostat behind the rear panel of the dryer.
That’ll depend on the exact model you have and its design, so refer to the user manual and tech sheet to be sure.
As always, disconnect the power supply before beginning any sort of work.
To replace it, you’ll simply need to remove its electrical connector and the screws keeping it in place.
Then, put the new thermostat in and work backwards: screw it in place, replace the connector, then put the rear panel back.
Control Board Heater Relay Failed
What it is: As you might know, the ‘brain’ of almost any household appliance is the main control board.
Even the one in your Samsung dryer coordinates and controls all of the appliance’s functions, including its ability to generate heat.
On that control board are a lot of electrical components controlling different parts of the dryer.
In this case, we’re looking at the relay on that control board that’s dedicated to supplying power to the heater when necessary.
Why it fails: While the rest of the control board might be functioning normally, the heater relay on the control board may be the part that’s failed.
Despite everything else functioning correctly, that failed heater relay means that the control board isn’t sending any power to the heater.
How to fix: Technically, it is possible to fix just the damaged heater relay alone.
Depending on where you live, you might be able to find a service that can do it for you.
However, the more straightforward solution would be to replace the main control board altogether.
You’ll usually find the main control board located behind the control panel on your dryer.
You may have to remove the top panel to gain access to it, though that might differ depending on the model you have. As always, refer to the user manual and technical sheet to be sure.
Once you’ve reached the board, remove its electrical connectors and mounting screws. Place the new board in, and replace those screws and connectors the same way as before.
Improper power Supply
What it is: A dryer is a power-hungry appliance, especially when it comes to the heating element.
To generate heat, the heating element inside the dryer requires a continuous two-phase 240V power supply.
Why it fails: Seeing as how the dryer relies on a two-phase power supply, it might be connected to double circuit breakers.
If one of those breakers trips, the dryer would only receive half the power it needs (i.e. 120V) and only from one phase.
In simple terms, the other parts of the dryer, like the motor or control board, might receive power and function correctly.
Still, the heating element will not receive power and therefore can’t generate any heat.
How to fix: To fix this, you must restore full power to your Samsung dryer. Check your circuit breakers and identify which ones power your dryer.
Then, ensure that both of them are switched back on. If the same breaker keeps tripping, that’s a sign that there’s a serious fault with your electrical system.
You’ll need to refer to a professional electrician to troubleshoot the problem and a dryer repair technician if that problem lies within the Samsung dryer itself.
Frequently Asked Questions
Here are a few frequently asked questions regarding Samsung dryers that aren’t heating.
Why Heating Element Keep Going Out?
Suppose you’ve replaced your burnt-out dryer heating element, and the new one burns out as well.
If that’s the case, then your dryer might be lacking proper airflow. Remember: the dryer needs good airflow to prevent overheating its parts, like the heating element.
Many homeowners neglect to clean their dryer vents and filters regularly. As a result, lint builds up and prevents the air from flowing efficiently.
No matter how clean you think your dryer vents are, they could always use another clean!
How Do You Know If The Heating Element Is Bad In A Dryer?
There are two ways you can inspect the heating element: visually and with a multimeter. To make it easier, you can remove your heating element and inspect it under a light.
Just by looking closely at the heating element, you might be able to spot breaks or burn marks on the coils. Those are clear signs that the heating element is bad.
You can also use a multimeter to test for continuity and resistance. You can do that by pressing the multimeter probes to the wire terminals on the heating element. Your meter should beep if the heating element is still functioning correctly.
Is It Worth Replacing A Heating Element In A Dryer?
Replacing a dryer’s heating element might be costly (depends on where you live of course), which is why some people consider buying a new dryer instead.
So, which should you do? Well, here’s a helpful rule of thumb: if the cost of repairing your existing dryer is 50% less than the price of a new dryer, then you should just repair it.
In other words, if the repairs will cost more than half the price of a new dryer, then you might want to pay the difference and get a brand new model!
How Much Does It Cost To Replace The Heating Element In A Samsung Dryer?
Replacing the heating element in a Samsung dryer will involve two costs: the replacement part and the labour costs.
Typically, a Samsung dryer heating element can cost anywhere from $50 to $150. Paying the technician to replace it for you will cost anywhere from $120 to $200 on top of that cost.
You could save a significant amount of money by replacing the heating element yourself.
However, you must have the know-how and experience to do it safely and correctly. If you’re ever unsure of yourself, it’s better to hire an expert to do it for you.

Hi, I replaced the heating element once, and the dryer worked for a year then aftewards one day the heat suddenly wouldnt turn on anymore. I checked the heating element, this time it wasnt broken (last time it burnt out and the wiring in the heating element was broken/disconnected – no continuity). But this time the heating element has continuity but i still replaced it, and replaced it with all the thermostat, thermal fuse, thermistor, they all show continuity except for the fuse i think im supposed to test on something else right? as it doesn’t beep but shows something else.
if i disconnect vent from vent from house, would it heat up? if it was due to a blocked vent? but does that not heat up right away? it seems no heat is even when i just start it.
I do apt maintenance newer Samsung dryer replaced the hear element dryer isn’t heating up could it be thermal cut off fuse or the cycling thermostat lost have checked everything I can
Us too…heat element, thermo fuse and thermostat all replaced.
Electrical perfect, and vent very clean.
Dryer is 1.5 years old. This is disgusting.
Dryer blowing out cold air. It’s new just had it delivered and hooked up. The one before that was new and was doing the same thing so we had them replace it. Had the same issue. Replaced the voltage and everything it’s not tripping the breaker so still don’t know what’s wrong.
It’s likely not receiving proper voltage. Check your circuit breaker in your fuse box and the outlet your dryer plugs into. It definitely sounds like an electrical issue.
My Samsung dryer won’t turn off toyed unplugging it and and did fuse box and still won’t shut
My dryer does not heat up while running, but when I unplug it for a bit and put the plug back in, the heating begins to work. The problem is that after a few drying cycles, it quits out again and I have to unplug again. I have cleaned out all the debris from the vent so I know that isn’t the problem.
My Samsung dryer (DV210AEW/XAA) always heats on high heat, even when I select “low heat”.
I checked thermistor, all the fuses and thermostat with ohmmeter. All behave the way they are supposed to.
Any idea what can be causing it?
How do you know that it is always on high heat? Did you measure temp on the dryer exhaust?
High heat (approximately 140-145 degrees Fahrenheit)
Medium heat (approximately 130-133 degrees Fahrenheit)
Low heat (approximately 120-122 degrees Fahrenheit)
I just touched the clothes and they were always about the same temperature.
but the biggest data point is that *sometimes* it heats high even when the setting is “fluff, no heat”. I could not figure out the pattern. There were cases when it honored “just fluff”, but most of the time it heats clothes continuously.
In this case, if you have heat even on Air FLuff:
1. Heating element shorted to the ground (you need a new heating element)
2. Control board relay stuck in ON position (new control board)
I’m having trouble with our 9 year old Samsung DV431. It runs but stopped heating, so I bought a kit off Amazon and on three attempts to fix and replace the heating element, thermistor, hi-temp cut off, thermal fuse, and the thermal fuse at the blower. All the original parts passed the continuity test and had the correct resistance, but I replaced them anyways just to rule them out. I tested the relay at the control box and got 120V from each of the blue and black wires (with the dryer on), and I tested 240V from the power supply of the dryer. I’m wondering what else could it possibly be. I’m preparing myself to contact a technician since I’m thinking this might be a control panel issue or something. On a positive note, I can’t believe I was able to disassemble and and reinstall the dryer.
“It runs but stopped heating” Is it doing this every time you run the dryer? Did you try to run the dryer without the hose attached?
Yes, it stopped heating no matter which setting I use. In the meantime, I connected a duct with an inline fan from the warm/dry loft space above the dryer to the intake of the dryer. I’m able to dry the clothes somewhat but it take about 3 hours. I’m trying to replace the PCB on the control box but the original DC92-00322M part is discontinued and I’m not sure if there’s a compatible updated part.
DV328AWG dryer heats properly for the first few minutes of the cycle, then shuts down for the remaining cycle time. Is this a cycling thermostat issue?
Sounds like.. But before replacing thermostat with a new one, test it… Using pliers, hold thermostat and heat it until it clicks.. Then you need a multimeter to check continuity.. if there will be no continuity for a couple of minutes, the thermostat is faulty.
I have a Samsung Dv45h7000ew/a2 dryer. It quit heating up so I got into it and tested the thermal cut-off switch and cycling thermostat. Both tested good. The element tested good as well but still no heating. I am getting power to the element itself and I have good air flow. Are there any sensors for the exhaust that could go bad thinking airflow was blocked by lint?
Disregard found the problem. One of the wires came loose on the power block and turned a wire into a spark plug till it burnt apart completely
Hi Mr. Smith.
I tested the heating element and the thermal cut-off switch and they show continuity. The Model is DV45H6300EG/A3. Is there anything else I can test before spending $196.00 on a new heating element? Genuine OEM Part # DC93-00154A. Thanks for your help!
If the heating element shows 10 Ohms resistance you don’t need to replace it.
Do your dryer not heating up at all?
We just replaced another heating element fuse and thermostat. The breaker tripped while in use. Now the dryer is not heating again and blowing cold air. No clog in vent line. Brand new parts yet again. Not sure what to do next here. Any suggestion would be great. I don’t think connections are bad either.
Hi Mr. Smith, the heating element on our Samsung Dryer Model DV42H5200EF/A3 went out and we replaced it only for it to short out again. This time we replaced the entire heating unit including the Cycling Thermostat and the Thermal Cut Off Fuse. We cleaned the as much of the vents as we could see and get to and turned on the dryer for about 10 minutes and it’s heating but now the right outside of the dryer is hot to the touch. Any suggestions? About to the point of just getting another dryer.
Dryer Hot to touch? Disconnect the vent hose from the dryer and let it run for 1 minute. Do you feel strong air flow coming from the dryer? If yes, then most likely dryer vent line is still partially or fully clogged.
I have the exact same thing happening. Replaced the entire heat assembly (twice) but still no heat. Any advice? Not clogged–strong air flow all of the way out to the exterior of the house
Check this video. But you have to have the proper tools to troubleshoot this issue. https://www.youtube.com/watch?v=I25dS6n6O8E
