For the Samsung Dryer families covered by the source set, **tC** means **temperature / temperature-sensor error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **tC**. Search normalization stores it as **TC** 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 TC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

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.
Depending on the exact model, heating, cooling, drying, or defrost behavior can become inconsistent.
Depending on the exact model, the display can return at a similar stage each time the affected sensor is checked.
When the tC condition is present, tC appears and drying may pause or performance may change because of temperature / temperature-sensor error.
One clue that supports the tC diagnosis is that heat, airflow, motor, drainage, door, or sensor behavior may 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 opening any service area, confirm vents, doors, filters, and ambient conditions are normal where they affect the sensor reading.
Before opening any service area, use the exact model manual before assuming the sensor itself is defective.
A safe owner-level check is to record the code and whether the dryer is vented or heat-pump/ventless.
To rule out an accessible cause, clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
To rule out an accessible cause, stop repeated resets if the code reappears; model-specific electrical/refrigeration diagnosis may 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 tC would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
Persistent temperature-sensor codes usually require resistance/connection checks at the sensor, harness, and control—work best done with the model-specific service procedure. A repeatable tC event is more useful diagnostically than repeated resets, because it shows when the temperature / temperature-sensor error check is failing.

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 **tC** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **tC** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **tC** 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 tC** separate from same-looking codes used by other Samsung appliance families.
