One common issue many Samsung dryer owners encounter is the Samsung Dryer Error Code tS, which stands for Temperature Sensor Error. While it might seem intimidating at first, understanding this error and knowing how to address it can save you both time and money.
In this post, we’ll break down what the tS error code means, what causes it, how to troubleshoot it, and when it’s time to call in professional appliance repair experts.
The tS error code on a Samsung dryer refers to a temperature sensor (also known as the thermistor) malfunction. This sensor is responsible for monitoring and regulating the dryer’s internal temperature during the drying cycle. If the sensor detects temperatures outside of its normal range—or if it stops communicating with the control board—you’ll see the tS code on the dryer display.
In some Samsung dryer models, this code may also appear as tO, tE, or tE1/tE2, depending on the model and region. All of these codes are related to temperature sensing issues.
The tS error can be triggered by several different issues, including:
1. Faulty Thermistor
The most common cause is a defective temperature sensor itself. Over time, thermistors can fail due to wear and tear, corrosion, or electrical issues.
2. Wiring Issues
Loose or damaged wires between the sensor and the control board can disrupt communication, triggering the tS error code.
3. Clogged Lint Filter or Vent
A restricted airflow system—such as a clogged lint trap or vent hose—can cause the dryer to overheat, confusing the sensor and generating an error.
4. Malfunctioning Control Board
In rare cases, the dryer’s main control board may be at fault if it fails to process sensor data properly.
Before calling a technician, there are a few troubleshooting steps you can try at home:
Unplug the dryer for 5 minutes to reset the internal electronics. Plug it back in and run a short cycle to see if the error persists. This may clear any temporary glitches.
Clean the lint trap thoroughly.
Inspect the vent hose at the back of the dryer. Look for blockages, lint buildup, or bends that could restrict airflow.
Ensure the exterior vent (where air exits your home) is not blocked by debris or snow.
You’ll need to remove the dryer’s rear panel to access the thermistor, which is usually located near the heating element. If you have a multimeter:
Disconnect the thermistor and test for resistance.
A functional thermistor should read approximately 10k ohms at room temperature.
If the reading is too high or low—or there’s no continuity—it’s likely faulty and needs replacement.
⚠️ Important: If you’re not comfortable working with electrical components, it’s best to contact a certified appliance technician.
If testing confirms that the thermistor is faulty, you’ll need to replace it. Here’s a general guide on how this process works:
Tools Needed:
Screwdrivers
Multimeter (for testing)
Replacement thermistor (compatible with your Samsung model)
General Steps:
Remove the back panel or front panel (depending on model) to access the thermistor.
Disconnect the old thermistor from its harness.
Install the new one and reconnect the wires.
Reassemble the dryer and test it.
Again, if you’re unsure, calling the professionals at Express Repair ensures the job is done right the first time.
While some homeowners may feel confident in testing or replacing a thermistor, others may prefer to avoid the risk of damaging sensitive components or voiding warranties.
Here are signs it’s time to call Express Repair:
You’re not comfortable opening your dryer.
You’ve replaced the thermistor but the error code still appears.
You suspect a control board malfunction.
The dryer is overheating or underheating despite your efforts.
At Express Repair, our licensed technicians are experienced with Samsung dryer repairs and can quickly diagnose and fix the tS error code, restoring your appliance to full working order.
To avoid dealing with the tS error in the future, here are some best practices:
Regular Cleaning
Clean the lint trap before every load.
Inspect and clean the vent system every 3–6 months.
Schedule professional vent cleaning annually.
Proper Loading
Avoid overloading your dryer, as this reduces airflow and can trigger overheating.
Scheduled Maintenance
Have your dryer inspected yearly by a certified technician to check internal components like thermistors, heating elements, and wiring.
The Samsung dryer tS error code is a common yet manageable issue. It’s typically caused by a faulty temperature sensor, airflow restriction, or wiring problems. While some homeowners may feel confident addressing the issue themselves, professional repair ensures long-term safety and efficiency.
