Samsung Dryer Light Blinking

A dryer is an essential appliance for many households as it makes drying laundry quick and easy. A blinking light on your Samsung dryer can be worrying and confusing. While it can indicate various issues, there are several common reasons the blinking light might come on.

A blinking light on a Samsung dryer could be due to a problem with the power supply, control panel, thermistor, or door. It could also be an error code reading. To fix these issues, replace or repair the affected parts.

In this article, I’ll discuss why your Samsung dryer’s light is blinking. I’ll also provide some helpful fixes. Let’s get started! 

1. Door Error

Samsung dryers have a safety feature that prevents them from operating when the door is open. If the door switch is faulty or not correctly aligned, it can cause the dryer to display an error code or the light to blink. There are several possible causes for a door error in a Samsung dryer, and the solution will depend on the issue causing the error.

How To Fix

To troubleshoot the cause of the door error, follow these steps: 

  1. Ensure that the door is properly closed and latched. Check that the door isn’t blocked in any way and that the door latch is securely engaged.
  2. Make sure the door switch is working well. If it’s faulty, it may be unable to detect when the door is properly closed, resulting in the dryer displaying a door error. In that case, you’ll need to replace the switch.
  3. Ensure that the door latch is in good working order. You can lubricate it with WD-40, but if that doesn’t work, you’ll need to replace the door latch as well.

2. Thermistor Errors

The thermistor is a temperature sensor that monitors the air temperature inside the dryer. If it fails or becomes disconnected, the dryer won’t heat up or might overheat, causing the dryer to display an error code and the light to blink.

How to Fix

Here’s how to fix a thermistor error on a Samsung dryer: 

  1. Inspect the wiring and make sure the thermistor is receiving power. 
  2. Check that the dryer vent isn’t clogged. A clogged dryer vent can overheat the dryer, causing the thermistor to register a high temperature. This problem can be resolved by cleaning out the dryer vent.
  3. Check if the thermistor is faulty. Over time, the thermistor can get worn out or damaged and might register wrong temperature readings as a result. This can be resolved by replacing the thermistor with a new, accurate one.

3. Heating Errors

The heating element is responsible for drying the clothes in the dryer. If the dryer gets too hot, it will flash an error code, and the light will blink. Alternatively, if the heating element fails, the dryer won’t be able to produce enough heat to dry the clothes, and a heating error will be displayed.

How to Fix

To fix a heating error, you’ll need to check the heater and its connections to ensure they are secure and functioning correctly. If it’s damaged or faulty, you’ll need to replace it.

Next, ensure the vent that exhausts the air from the dryer to the outside isn’t clogged. This vent helps to keep the dryer from overheating. To avoid this problem, clean the vent of lint and debris regularly.

Another cause for the problem might be a faulty control board or thermistor. The control board manages power for different dryer components while the thermistor regulates temperature. Check that both are working fine and replace them if necessary. 

4. Venting Errors

A venting error typically points to a problem with the dryer’s venting system, which is responsible for removing the hot air and moisture during the drying cycle. If the vent becomes clogged or damaged, it can cause the dryer to blink an error code.

How to Fix

To correct a venting error, inspect the dryer’s vent system for obstructions and ensure that the venting is properly installed. If the vent is clogged or damaged, clean it or replace it.

If the venting wasn’t installed correctly, you must reinstall it according to the manufacturer’s instructions. The user manual explains this in detail.

5. Control Panel Errors

The control board is the “brain” of the dryer. It manages the power supply to the various components and receives sensor inputs to control the drying cycle. If it fails or becomes damaged to the extent that it won’t sense, it can cause the dryer to blink an incorrect error code.

How to Fix

A control board error in a Samsung dryer can be caused by various factors, including power surges, software problems, or physical damage. You can try the following steps to solve this problem:

  1. Check the power supply and make sure the dryer light is plugged into a working outlet. 
  2. Check if the control board requires a software update. Software that is out of date can become buggy and problematic.
  3. Inspect the control board to ensure it is free of physical damage that could interfere with its operation. In case of irreparable damages, you might need to replace the control board with a new one.

How To Prevent Problems in a Samsung Dryer

By performing simple and regular maintenance, you can keep your Samsung dryer running efficiently and help prevent problems that can cause the light to blink and error codes to appear.

Here are some helpful maintenance tips you can do to ensure your dryer is always in good condition:

  • Clean the lint filter regularly. To clean the lint filter, open the dryer door and remove the lint filter. Then, use a soft brush or vacuum to remove any lint or debris accumulated on the filter. It’s wise to clean the lint filter after every load of laundry or at least weekly.
  • Inspect and clean the dryer’s ventilation system. To inspect and clean the ventilation system, inspect the ventilation hose connecting the dryer to the exterior vent cap. Ensure the hose isn’t kinked or crushed, which can restrict airflow. Then, inspect the exterior vent cap to ensure that there’s no debris or lint clogging it. 
  • Clean the dryer drum and the inside of the door regularly to remove any accumulated lint or debris.
  • Inspect the dryer’s power cord and outlet periodically to ensure they function correctly and that there are no signs of wear and tear or damage.
  • Consult the user manual and follow the manufacturer’s recommended maintenance and care guidelines.


If your Samsung dryer displays an error code, it’s critical that you diagnose and resolve the problem as soon as possible. Failure to do so may result in the dryer malfunctioning, potentially being a fire hazard or causing damage to your clothes.

If you can’t diagnose and repair the problem yourself, it is best to seek the assistance of a qualified appliance repair technician.
