Samsung Dryer is Not Heating Up

Nowadays, the dryer is important to you. It allows you to dry your clothes in just a few minutes. However, dryers can easily break down without requiring maintenance.

Is your Samsung dryer suddenly not heating up? This article is written for when your dryer works fine but sometimes doesn’t. Imagine doing laundry on Sunday night and then realizing the dryer isn’t working and you have nothing to wear on Monday morning.

There may be many reasons why your Samsung dryer is not heating. In this article, we discuss all these reasons and recommendations. You should read our suggestions carefully and try it yourself.

How To Fix Samsung Dryer Not Heating  

Thermal Fuse

The first thing to check is the thermal fuse. The purpose of this product is to help protect the dryer if it starts to overheat.

To check the thermal fuse

  • Make sure the power to the dryer is off.
  • Remove the top and side panels, and Locate the thermal fuse.
  • You can find this on the heater or the dryer’s heating element. 
  • For an oil-based heater, it will be on the heater, for an electric dryer it will depend on the heat.
  • Once you find it, you should use a multimeter to check its continuity.
  • When checking the fuse, its continuity must be off. This means there must be a permanent electrical connection via it.
  • When the fuse does not work, it must be replaced because it is blown.
  • After replacing the fuse, you must ensure the port is not clogged.
  • If it is, remove it so that the fuse does not blow in the future.

Gas Valve Solenoid And Igniter

If you have a dryer, the next thing you need to check is the gas valve solenoid and igniter (if your dryer is electric, skip to Equipment Inspection). Depending on the specific model of your Samsung dryer, there may be two or more fuel valve solenoid coils that help open the fuel valve port so fuel can flow into the assembly. The igniter then ignites the oil so the dryer can heat up. If any of these parts malfunction, your dryer will not heat.

To check these

  • To check whether the fuel valve solenoid valve is correct, you must check whether the igniter works properly. To do this you need to see if the igniter lights up and ignites the fuel or if it goes out without electricity.
  • If the igniter does not light at all, check its continuity. If the igniter does not continue to work, it should be replaced.
  • All fuel valve coils must be replaced if the fuel does not ignite but the igniter glows.
  • If the fuel valve solenoid or igniter has been replaced, check if the problem is solved. Sometimes you need to replace both at the same time.

Flame Sensor

If it is a dryer, another issue that will cause the dryer not to heat up is the poor quality of the flame. The flame sensor detects how hot your dryer is; when it’s not working, it won’t get hot.

To check the flame sensor 

  • Flame retardants are easy to control; All you need to do is.
  • Make sure the dryer is turned off.
  • Find the flame (if you can’t find it, remove the top and side panels).
  • Check sensor continuity using a multimeter (ensure it is at room temperature when testing).
  • If the sensor has an extension, it works fine and you can switch to the extension. However, if the test is ineffective, it should be replaced.

Check the Input Power Supply

Another reason for your Samsung dryer not working is that there is a problem with the power input of the machine, drying clothes. An electric dryer requires two 120-volt AC voltages (250 volts total) to operate properly. Sometimes one of the fuses can blow, which means the dryer is still running but not heating.

To check the fuse:

  • Locate your home’s fuse box.
  • Find the right fuse for your dryer.
  • If you don’t want to replace it, test each fuse with a multimeter to ensure it has the correct voltage.

High Limit Thermostat

If a power problem does not cause the problem, the next thing to check is the high-limit thermostat. This temperature sensor measures the temperature inside the dryer and turns off the oven if the dryer overheats. If a problem occurs, your dryer may shut down even though it should not.

Check the temperature display:

  • Make sure the power is still off.
  • Find the thermometer above the temperature.
  • Use a multimeter to test if the thermostat has continuity.
  • If the test does not provide continuity, it should be replaced; If an extension is available, it works fine, and you can continue checking it.

Cycle Thermostat

  • In case of malfunction, the dryer will not heat up.
  • To check the temperature of the bike:
  • Make sure the power is still off.
  • Find a thermometer.
  • Check the temperature gauge for continuity with a probe.
  • If the test does not show continuity, it should be replaced; If an extension is available, it works fine, and you can continue checking the extension.


If you still haven’t found the reason for your dryer not heating up, the next thing you can check is the timer. The timer on your dryer doesn’t work very often, but this can happen. If you have checked all other appliances above, check the time:

Make sure the power to the dryer is still off.

  • Find the timer.
  • Use a multimeter to check if the timer is working.
  • If it continues, it works normally; if it does not, it needs to be replaced.

Main Control Board

If you cannot find the cause of the problem, your last option is to replace the motherboard. The main board is the brains of the dryer, and if it fails, the dryer will not function properly. Control boards are difficult to test, so if you’ve tried everything else consider replacing the control board and see if that fixes the problem. However, depending on the age of your dryer, purchasing a new dryer may be a better option.

Why isn’t my Samsung dryer heating up?


The dryer is difficult to operate properly.

The longer a clog goes untreated, the more likely lint and dust will accumulate and cause a large clog. Also, outdoor vents may be blocked by bird nests, leaves, or other objects. The easiest way to check for a clog is to check both ends of the vent: at the back of the dryer and near where the hose connects to the house.

Blown Thermal Fuse.

This fuse is usually located on the back or side of the dryer and its purpose is to prevent heat by cutting off the electricity when the temperature drops. too loud on the machine.

If your thermal fuse becomes damaged due to age or incorrect wiring, it will not work correctly and will cause the dryer not to heat.

The Door Switch Not Working.

The door switch is on the front of the dryer. It serves as a safety measure to ensure that no energy passes through the machine when the door is open and that no one receives electricity by touching the side of the device.

Unfortunately, these keys take a long time due to constant use and may not work. If you suspect this may be causing a problem with your dryer, the replacement cover needs to be replaced or repaired as soon as possible.

Damaged Air Conditioner

The heater keeps your clothes warm and dry by heating the drum. If it breaks, you must replace your dryer to repair it. Heating products can present themselves in many different ways, from lack of heat to irregularity and even odor from the device.

You should always take these signs seriously and consult a professional if you think this is the cause of your problem. The technician will be able to detect a problem with the equipment and advise you on how to fix the problem.
