Why is My Samsung Dryer Not Heating Up? – Let’s Fix It

Samsung Dryer Not Heating: Every day, we throw our damp clothes into our dryers and turn them on without giving it a second thought. Everyone expects that once the door is shut and the drying cycle is started, the machine will heat up and do its work. But what if your Samsung dryer doesn’t heat up properly?

A burnt heating element is the most common cause of a Samsung dryer not heating up, with a blown thermal cut-off fuse, cycling thermostat, or a failed control board heater relay accounting for the remaining 18%. The final 2% was caused by a faulty power supply.

In this article, we’ll look at some of the most common reasons why your Samsung dryer won’t heat up. When Your Samsung Dryer Isn’t Heating, Here’s What to Do Heating Element That Has Been Burned

Why Is My Samsung Dryer Not Heating Up?

What it entails: To efficiently dry your clothing, your Samsung dryer must first generate heat. This is when the heating element enters the picture.

Appliance Repair Guides: The exact design of the heating element varies depending on the model. Nonetheless, they all operate in a similar manner. The machine sends power to the heating element when it requires heat. Heat is generated by the heating element, which is then forced further into the dryer by a blower fan. That hot, flowing air draws moisture out of your clothes and dries them in your Samsung dryer.

Why it fails: When a Samsung dryer won’t heat up, it’s almost often due to a burned-out heating element. You may check whether this is the case by visually inspecting the heating element on your Samsung dryer or using a multimeter. When checking the resistance of the heating element using a multimeter, the measurement should be around 10 Ohms. If this is the case, your heating element is in good operating condition. Aside from that, get a flashlight and examine the entire heating element closely.

Burned out elements emit a burnt odour and have burn marks running the length of the element

To resolve this issue, you will need to replace the heating element. It’s not difficult to accomplish this. Reaching the heating element housing, on the other hand, is what makes this a labour intensive and time-consuming repair job. To avoid harm and electrocution, always begin any repairs by turning off the dryer’s power supply.

Then, as a quick reference, keep your user handbook and technical sheet close by. This will assist you in locating and identifying your model’s heating element, which will be housed somewhere along with the air vents. To reach there, you may need to take off a few elements, including the drum and any other obstructions.

However, after you’ve gotten to the housing, you’ll need to remove the present heating element and separate the electrical contacts that are connected to it. Replace the replacement in the same manner, then work your way backwards by reinstalling any components or panels you removed previously.

Thermal Cut-Off Fuse That Has Been Burned

What it entails: There’s an extra component that protects home appliances that create heat (like your stove or, in this case, your Samsung dryer) from overheating. The thermal cut-off fuse is the name for this component. Because they burn or blow out to safeguard the remainder of the appliance, they’re called a ‘sacrificial device. In this situation, a thermal cut-off fuse at the heater assembly protects against overheating on your Samsung dryer. The thermal cut-off fuse will burn out if temperatures grow too high, preventing the dryer from heating up.

When a Samsung dryer fails to heat up, there’s a 10% possibility it’s due to a burned thermal cut-off fuse in the heater assembly. As previously stated, this occurs when the temperature around the heater component increases above safe levels, causing the fuse to blow, protecting the rest of the machine from damage. The vents in the dryer are usually clogged, resulting in overheating.

The heater assembly overheats and the thermal cut-off fuse burns if there isn’t enough airflow to transfer heat away from the heating components

How to solve the problem: There are two components to resolving this issue. To begin, replace the thermal cut-off fuse that has burned out. These are ‘disposable’ parts because they cannot be fixed. It is only possible to replace them. Before making any repairs, turn off the power supply as usual. Additionally, keep a copy of your user manual and technical sheet on hand for easy reference. That will serve as a guide when you remove the essential panels (usually the back panel) in order to gain access to the heater assembly.

Another thing to keep in mind is that if the heater assembly is still hot, you should not work on it until it has completely cooled down. After that, remove the burned fuse and replace it with a new one. Replacing the fuse simply addresses the symptom, not the underlying problem. To guarantee appropriate ventilation and avoid overheating, clean out all of the dryer’s vents.

Thermostat Failed to Cycle

What it is: Until the completion of the drying cycle, your Samsung dryer does not generate heat continually. Instead, it merely produces heat until the target temperature is reached before turning off the heater. When the temperature falls too low, it will restart the heating procedure as many times as necessary to keep the temperature at the proper level throughout the cycle.

Your dryer has a cycle thermostat to guarantee that the heater turns on and off only when necessary. It detects whether temperatures are too low or too high and responds appropriately.

Why does it fail? The cycling thermostat is constantly in use and may eventually fail. When this happens, the dryer may not recognise that the temperature inside is too low and fails to switch on the heater. If you’ve had your Samsung dryer for a long time, the thermostat may have suffered from excessive wear and tear and is no longer functioning properly.

By examining the resistance of the cycling thermostat with your multimeter, you can diagnose it.

A working thermostat should read between 0.1 and 0.5 Ohms. If it’s broken and needs to be changed, though, it’ll display an infinite reading.

How to fix: The cycling thermostat is usually located behind the dryer’s back panel. That will vary depending on the model and its design, so check the user handbook and tech sheet to be sure. Before starting any work, be sure the power supply is turned off. To replace it, all you have to do is unscrew the electrical connector and the screws that hold it in place. Then screw in the replacement thermostat and work backwards: screw it in, replace the connector, and then repair the back panel.

Heater Relay on Control Board Failed

What it entails: The main control board, as you may know, is the ‘brain’ of practically every domestic device. Even the one in your Samsung dryer coordinates and manages all of the appliance’s functions, including its heat-generating capability. There are a lot of electrical components on that control board that govern different portions of the dryer.

We’re looking at the relay on that control board that’s responsible for giving electricity to the heater when it’s needed.

Why it fails: The heating relay on the control board may be the part that fails, even if the rest of the control board is working properly. Despite everything else working properly, the control board isn’t transmitting any electricity to the heater since the heater relay is broken.

How to fix: It is technically possible to repair only the damaged heating relay. You might be able to discover a service that can do it for you depending on where you live. The most straightforward approach, on the other hand, would be to replace the primary control board entirely. The main control board for your dryer is normally hidden underneath the control panel.

To get to it, you might have to remove the top panel, however, this will depend on the model you have. Always double-check the user manual and technical sheet for accuracy. Remove the board’s electrical connectors and mounting screws after you’ve reached it. Replace the old board and the screws and connectors in the same manner as before.
