tS2
Samsung Dryer
Severity: ModerateWhat Does This Error Mean?
The tS2 error means the exhaust outlet temperature sensor (thermistor) in your Samsung dryer is reading an abnormal value. This sensor monitors the temperature of air leaving the drum. When it fails, the dryer cannot manage heat safely.
Affected Models
- DVE45R6100W
- DVE50R8500V
- DV45H7000EW
- DV50K8600EV
- Samsung electric dryers with sensor dry
Common Causes
- Faulty outlet thermistor — the sensor has failed or drifted outside its operating range
- Loose or disconnected wiring connector at the thermistor
- Blocked exhaust vent causing outlet temperatures to rise abnormally
- Lint or debris coating the thermistor probe and affecting its readings
- Control board fault causing incorrect temperature signal interpretation
How to Fix It
-
Clean the lint screen and check the exhaust vent.
A blocked vent causes exhaust temperatures to spike, which can trigger tS2 even on a healthy thermistor. Always rule out vent issues first.
-
Unplug the dryer for 10 minutes, then plug back in.
A reset clears temporary thermistor faults. If tS2 was caused by a brief overtemperature event, the error may not return after a full cool-down.
-
Run a short cycle to see if tS2 returns.
If the error clears after the reset and the vent is clean, monitor for a recurrence. If it comes back, the thermistor itself is failing.
-
If tS2 returns, do not continue using the dryer for heated cycles.
Without a working outlet thermistor, the dryer cannot safely regulate temperature. Running it risks overheating.
-
Schedule a technician to test and replace the outlet thermistor.
Provide the tech with the tS2 code and your model number. The thermistor is a small, inexpensive part — the labor is the main cost.
When to Call a Professional
The tS2 error typically requires replacing the outlet thermistor. This sensor is located in the exhaust duct inside the dryer. A technician can replace it in under an hour. Expect costs of $80–$180 including parts and labor.
Frequently Asked Questions
What is the difference between tS and tS2 on Samsung dryers?
The tS code is the general thermistor error. The tS2 code is specific to the outlet (exhaust) temperature sensor — the one that monitors air leaving the drum. Different sensors have different codes so a technician can pinpoint which one needs replacing.
Can I use my Samsung dryer on Air Dry with the tS2 error?
Generally yes — an Air Dry or no-heat tumble cycle does not use the heating system. However, the auto-dry sensor may not work correctly without the thermistor. Avoid timed heat cycles until the thermistor is replaced.
How long do Samsung dryer thermistors typically last?
Most thermistors last the full lifespan of the dryer — 10 to 15 years. Premature failure is usually caused by chronic overheating from vent blockages. Keeping the vent clean and the lint screen clear is the best way to protect all heat-sensitive components.
