Seeing **tS** on a Samsung dryer narrows the problem to **temperature / temperature-sensor error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **tS**. Search normalization stores it as **TS** while preserving the characters a homeowner actually sees.

Quick answer
Temperature / temperature-sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so TS may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Seeing **tS** on a Samsung dryer narrows the problem to **temperature / temperature-sensor error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. Samsung uses overlapping code conventions across model years and regions.

Signs
Symptoms you may notice
Depending on the exact model, the control may stop or limit operation because a temperature reading is missing or implausible.
A symptom that fits tS is that heating, cooling, drying, or defrost behavior can become inconsistent.
A symptom that fits tS is that the display may return at a similar stage each time the affected sensor is checked.
tS can be accompanied by this pattern: tS appears and drying may pause or performance may change because of temperature / temperature-sensor error.
Depending on the exact model, heat, airflow, motor, drainage, door, or sensor behavior can be affected depending on the code family.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Before opening any service area, record when the code appears and whether the appliance had just heated, cooled, or defrosted.
Before requesting service for tS, confirm vents, doors, filters, and ambient conditions are normal where they affect the sensor reading.
Before requesting service for tS, use the exact model manual before assuming the sensor itself is defective.
For tS, start by doing this: record the code and whether the dryer is vented or heat-pump/ventless.
Before opening any service area, clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
As an external check for tS, stop repeated resets if the code returns; model-specific electrical/refrigeration diagnosis can be required.
Important safety warning. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection. If resolving tS would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
Once tS has returned after the safe checks, Persistent temperature-sensor codes usually require resistance/connection checks at the sensor, harness, and control—work best done with the model-specific service procedure. Preserve any accompanying noise, water level, temperature, or operating-stage details for the technician.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **tS** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Do not keep operating the appliance through a hazardous symptom just to see whether **tS** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
The code alone is not enough to justify a part. **tS** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Dryer tS** separate from same-looking codes used by other Samsung appliance families.
