The **tC5** display on a Samsung dryer points to **temperature / temperature-sensor error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. 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 **tC5**. Search normalization stores it as **TC5** 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 TC5 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.
One clue that supports the tC5 diagnosis is that the display can return at a similar stage each time the affected sensor is checked.
On affected Samsung dryer models, tC5 appears and drying can pause or performance may change because of temperature / temperature-sensor error.
tC5 can be accompanied by this pattern: 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 opening any service area, confirm vents, doors, filters, and ambient conditions are normal where they affect the sensor reading.
To rule out an accessible cause, use the exact model manual before assuming the sensor itself is defective.
With tC5 recorded, record the code and whether the dryer is vented or heat-pump/ventless.
For tC5, start by doing this: clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
A safe owner-level check is to stop repeated resets if the code reappears; model-specific electrical/refrigeration diagnosis may be required.
Important safety warning. When working around a dryer that shows tC5, keep the checks external and non-invasive. Stop for burning smell, smoke, gas odor, repeated breaker trips, or abnormal overheating. Do not bypass thermal protection.

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 tC5 event is more useful diagnostically than repeated resets, because it shows when the temperature / temperature-sensor error check is failing.
Book your repair
Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
A single documented power reset can help after an external condition or power event is corrected. If **tC5** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
Do not keep operating the appliance through a hazardous symptom just to see whether **tC5** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
Treat **tC5** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
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 tC5** separate from same-looking codes used by other Samsung appliance families.
