Why Is My Samsung Dryer Not Heating Up?

Samsung dryer

No matter what time of year it is, a clothes dryer at home makes life relatively easy. However, many users face a common dryer issue. The machine stops heating correctly within a year of buying it. This situation is frustrating, but we can offer some insight on what causes this and how to make sure it doesn’t happen again in the future.

According to various sources, around 30% of new buyers face this issue right after their first year and blame the company.

When it comes to a heating problem in Samsung dryers, there are many causes, most of which are user-created. Mentioned below are possible roots to this problem:

  1. Bad/broken heating element
  2. Bad thermistor/thermostat
  3. Clogged dryer vent/chimney
  4. Clogged Lint-filter inside the dryer
  5. Overheating
  6. Using the dryer for prolonged hours
  7. Overloading
  8. Sudden power surge
  9. Dirty/damaged moisture sensors

We will address each issue in detail, but first, we need to understand how a Samsung dryer works.

A Samsung dryer is a machine that dries wet clothes by taking in fresh air from the surroundings, passing it through a heating component, and using that hot air to dry the clothes. The hot, moist air gets pushed out through a vent connected to another vent inside a nearby wall. After this, it gets outside through a chimney.

Now that we know how the dryer works let’s look at each of the issues that cause heating problems and address them.

1. Bad/broken heating element

9 out of 10 times, the heating function doesn’t work in a Samsung dryer because of a broken heating element. A heating element breaks when a dryer is overused for prolonged hours or clogged vents. It’s best to check your vents, lint trap, and chimney for any lint.

Lint buildup can restrict air flow from the machine causing heat to build up inside the dryer, which causes the part to overheat and break.

The recommendation to fix it is to clean the wall vents and chimney at least once a year and the lint filter inside the dryer regularly to give a clear path for the hot air to flow in and out.

2. Bad Thermostat

Out of many complaints related to Samsung dryer heating issues, some are for a malfunctioning thermostat. A thermostat is a small electronic device inside a dryer that controls and regulates hot air temperature flowing inside.

A non-functioning thermostat could cause insufficient heating or a complete shutdown of the heating element in the dryer.

To diagnose this, you can use a multimeter to check the thermal fuse and run continuity tests. To do this, you need to locate the thermal fuse by removing the back panel. It is usually near the blower or the heating element. Once you’ve found it, use the multimeter for the continuity test. If it fails, then it is time to replace it.

3. Clogged Dryer Vent/Chimney

Another reason your Samsung dryer’s heating function isn’t working correctly could be a clogged dryer vent or chimney. Dryers pass hot air to the wet clothes to dry them and expel the hot and now moist air out through its vent. A clogged dryer vent could restrict the outgoing hot air, which in turn causes heat to build up inside the dryer, which overheats & breaks the heating element.

Or it could be a clogged chimney. The chimney connected to your dryer vent should be clear for the wet and moist air to pass through it quickly. Another problem could be the clogged grate at the opening of the chimney on the roof. It should also be checked regularly for any lint formation and cleaned accordingly. A blocked chimney is a big reason for house fires, as the clogged lint can catch fire due to the restricted hot air.

A good recommendation is to clean both the dryer vent and the chimney regularly, creating a clear path for the air to flow out of the dryer and to the outside.

4. Clogged Lint-Filter Inside the Dryer

Another reason for the improper heating effect of the dryer is a clogged lint filter (also known as a lint trap) located inside the dryer. A lint filter is placed inside the dryer to filter unwanted lint and other micro-particles from the clothes and restrict their movement. A clogged lint filter can also limit the inflow of hot air, which could cause your dryer to overheat and the gradual breakdown of the heating components. That’s why experts advise cleaning it regularly.

5. Overheating

Overheating is the prime issue that causes heating problems in Samsung dryers. A broken heating element or a clogged dryer vent and lint filter cause overheating. It can also be due to a bad or broken thermistor or thermostat. Overheating happens when either hot air cannot flow inside the dryer tub or outside the dryer via its vent. When this happens, the hot air gets trapped inside and builds up heat which in turn causes the heating element to break. Clean the vent, chimney, and lint filter thoroughly regularly to avoid this problem.

6. Using The Dryer for Prolonged Hours

Another issue that causes the heating issue in a dryer is overuse. Like any machine, a dryer is a machine that wears out with time at the end of the day. Overusing a machine causes wear & tear faster and sometimes renders it or certain parts unusable. The same thing happens with your Samsung dryer. Overusing can put excessive pressure on its motor and wear out its most important part – the heating element. This can drastically reduce its life and increase service costs. It is not advised to overuse your Samsung dryer as it can cause failure in its operation and increase your chances of calling a technician.

7. Overloading

Overloading a machine causes it to overwork, thereby reducing its longevity and increasing the chance of breakdown. The same happens with your Samsung dryer. When you overload your drying drum, the dryer must work harder to dry to the load, and it takes longer. Overloading not only leads to overheating but also may leave some clothes still damp.

The hot air coming from the heating element needs some space to move freely inside the drum, and tightly packing the drum restricts this movement and making the drying process inefficient. The recommendation is to fill the drum up to 75% of its total capacity to make the drying process efficient. This eases the load on the machine and enables the hot air to flow throughout the drum without restriction.

Splitting up large loads into smaller ones is highly recommended as it speeds up the process, saves time, and increases the longevity of your dryer.

8. Sudden Power Surge

A sudden power surge could also break your heating element that may cause a heating issue with your Samsung dryer.

You can’t avoid a sudden power surge, but you can use the following methods to keep your Samsung dryer and other household appliances safe.

  1. Using surge protection strips is the easiest and least expensive method to protect your household appliances from sudden power surges. You can use power strips with built-in surge protectors instead of directly plugging your appliances in the AC power socket.
  1. A better method to avoid sudden power surges is to install a snap-in surge protector directly into the house’s main electrical panel.
  1. You can also contact your local electricity provider for meter-mounted surge protector. This is the best method to control sudden power surges right from the incoming power line.
  1. Finally, you can use a UPS or Uninterrupted Power Supply unit for all your electrical appliances as it stores backup, to use it during a power outage without any interruption. It also has surge protectors to protect your appliances from sudden power surges.

You can adopt one of the methods mentioned above not just to safeguard your Samsung dryer but other household electrical appliances from sudden power surges and outages.

9. Dirty/Damaged Moisture Sensors

Dirty or damaged moisture sensors are another reason why your Samsung dryer could be acting strangely. The moisture sensing sensors work to sense the amount of moisture inside the clothes and accordingly rotate the drum to regulate the inflow of hot air inside.

To know if the sensors are working fine or not, time the drying cycle. If it ends in a couple of minutes, then this could be a problem. If it takes its regular time, it could be another reason from the many listed above in the article.

A dryer is a necessary appliance as it eases the effort it takes to dry clothes. But running into a problem like a heating issue could cause more trouble and frustration, so always use the dryer carefully and always keep the vents and chimneys clean and clear.

This guide is designed specifically for Samsung dryers and their owners to help them out if they face heating issues.

The problems mentioned above and their detailed solutions should be sufficient for any Samsung dryer owner facing a heating issue. However, if nothing from the guide works, it is time to consult a professional to help you with a quick & easy fix.
