Samsung Dryer tS error code
The dryer's temperature sensor (thermistor) is shorted - its resistance reads far too low. The dryer cannot measure heat accurately, so it stops.
Also shown as: tS, TS, t5
Last updated: October 6, 2026
What causes the tS error?
- Shorted thermistor
- Overheating that damaged the thermistor
- Pinched or shorted thermistor wiring
- Clogged vent causing heat damage to the sensor
- Failed main control board misreading the sensor
How to fix Samsung tS — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Clean the lint filter and vent first
Overheating from blocked airflow is what usually kills the thermistor. Clean the filter thoroughly and check the vent hose for kinks or lint packing before anything else.Safety warning: Unplug the dryer before pulling it out to inspect the vent. - Power-cycle the dryer
Unplug the dryer for 2 to 5 minutes, then plug it back in. A transient glitch can throw tS once; a persistent code means the sensor is genuinely shorted. - Let the dryer cool completely
If the dryer was running hot, unplug it and let it cool for at least 30 minutes. A heat-soaked sensor can read out of range until it cools.
When to call a technician
- tS returns after cleaning and a full cool-down
- The thermistor needs multimeter testing or replacement
- The wiring harness is pinched or shorted
- The main control board is misreading the sensor
Frequently asked questions
What is a thermistor?
It is the dryer's temperature sensor - a small part whose electrical resistance changes with heat. 'Shorted' means its resistance dropped far below normal, so the control cannot trust its readings.
Can I test the thermistor myself?
It should read around 10k ohms at room temperature with a multimeter, but reaching it means opening the dryer. If you are not comfortable with that, call a technician.
Will the dryer work at all with tS?
No. Without a trustworthy temperature reading, the dryer locks out heating and the cycle for safety.
