Short answer: A Samsung dryer not turning off may be due to a faulty door switch or a malfunctioning control board. Troubleshoot and replace the faulty component to resolve the issue.
Samsung dryers have earned a reputation for their efficiency and convenience, but like any appliance, they can encounter issues that require troubleshooting and repair. One common problem users may encounter is a Samsung dryer not turning off when it should. This puzzling issue can leave you wondering why your dryer keeps running even after the cycle is complete. In this guide, I’ll explore the possible causes of this problem and provide step-by-step solutions to help you diagnose and fix the issue, ensuring your dryer operates as it should, saving you time, energy, and potential repair costs.
Why Is Your Samsung Dryer Not Turning Off?
If your Samsung dryer is not turning off, there could be several reasons for this issue. It might be due to the activation of the “Wrinkle Prevent” feature, which keeps the dryer tumbling after the cycle ends to prevent wrinkles. Another common cause could be a faulty or clogged moisture sensor that fails to detect the laundry’s dryness accurately. Additionally, a malfunctioning door switch might not register when the door is open, preventing the dryer from stopping. Problems with the dryer timer, a damaged control board (PCB), a malfunctioning start button, a motor relay failure, or a clogged blower wheel could also lead to the dryer not shutting off as expected. Identifying the specific cause will require troubleshooting and potentially repairing or replacing the relevant components.
Common Causes Of A Samsung Dryer Not Turning Off
Here are some common causes of a Samsung dryer not turning off:
- Wrinkle Prevent Activated: Some Samsung dryers have a “Wrinkle Prevent” feature that keeps the dryer tumbling periodically after the cycle ends to prevent wrinkles. Make sure this feature is turned off if you want the dryer to stop completely.
- Clogged or Faulty Moisture Sensor: The moisture sensor detects the dryness of the laundry. If it’s clogged with lint or damaged, it may not accurately sense the moisture level, causing the dryer to continue running.
- Faulty Door Switch: The door switch is a safety feature that should stop the dryer when the door is opened. If the door switch is malfunctioning, it may not register when the door is open, allowing the dryer to keep running.
- Dryer Timer Failure: The timer on the dryer controls the duration of the drying cycle. If the timer is faulty, it may not advance to the off position, causing the dryer to run continuously.
- Damaged Printed Circuit Board (PCB): The PCB, or control board, is the brain of the dryer. If it’s damaged or malfunctioning, it can result in various control issues, including the dryer not turning off when it should.
- Start Button Malfunction: A malfunctioning start button can prevent the dryer from responding correctly to your commands, causing it to keep running even when you try to turn it off.
- Motor Relay Failure: The motor relay controls the operation of the dryer’s motor. If it fails, it can keep the motor running even when it’s supposed to be off.
- Clogged Blower Wheel: A clogged blower wheel can restrict airflow in the dryer, affecting its ability to cool down and shut off properly. This can result in extended drying times and the dryer not turning off promptly.

FAQs
Why is my Samsung dryer not spinning?
If your Samsung dryer is not spinning, there could be several reasons. Check if the belt that drives the drum is intact and properly tensioned. A broken or loose belt can cause the drum not to spin. Additionally, inspect the idler pulley and drum rollers for wear and replace them if necessary. Another potential issue could be a malfunctioning motor or motor relay.
Why does my Samsung dryer keep shutting off?
If your Samsung dryer keeps shutting off prematurely, it could be due to a few common issues. First, check if the lint filter and exhaust vent are clean and not blocked, as poor airflow can cause overheating and shutdown. Secondly, ensure that the moisture sensor inside the drum is clean and functioning correctly. A faulty moisture sensor may misinterpret the dryness level, leading to early shutdown. Finally, a malfunctioning thermostat or control board could also be causing the issue and may require replacement.
Why is my Samsung dryer squeaking?
A squeaking noise in your Samsung dryer can be attributed to several factors. One common cause is worn or damaged drum rollers or idler pulleys. These components support the drum and can squeak when they wear out. Lubricating or replacing these parts can resolve the squeaking issue. Additionally, inspect the drive belt for wear or damage, as a damaged belt can produce squeaking sounds. Regular maintenance and lubrication of moving parts can help prevent squeaking.
Why is my dryer not turning on?
If your dryer is not turning on, start by checking the power supply. Ensure that it’s properly plugged in and that the circuit breaker or fuse for the dryer is not tripped or blown. If the power supply is not the issue, it could be a faulty door switch, thermal fuse, or start switch. Test these components with a multimeter to identify the problem. If you’re uncertain or unable to diagnose the issue, consider consulting a professional technician for a thorough inspection and repair.
Conclusion
When dealing with a Samsung dryer that refuses to turn off, it’s crucial to investigate and troubleshoot various potential causes. These issues can range from sensor malfunctions to faulty components like the door switch or control board. By carefully diagnosing and addressing the specific problem, whether through cleaning, part replacement, or maintenance, you can restore your Samsung dryer to its normal functioning and ensure it operates efficiently, saving you time and hassle in the long run.
