If a Samsung dryer shows **1 tC**, the verified Samsung meaning in this research set is **temperature / temperature-sensor error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **1 tC**. Search normalization stores it as **1TC** 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 1TC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
If a Samsung dryer shows **1 tC**, the verified Samsung meaning in this research set is **temperature / temperature-sensor error**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. Samsung appliances monitor whether a function reaches an expected state within a certain sequence. When that check fails, the control can store or display a code even though the root cause may sit elsewhere in the same circuit. The recorded display form is **1 tC**. Search normalization stores it as **1TC** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
One clue that supports the 1 tC diagnosis is that the control may stop or limit operation because a temperature reading is missing or implausible.
While 1 tC is active, heating, cooling, drying, or defrost behavior can become inconsistent.
A symptom that fits 1 tC is that the display may return at a similar stage each time the affected sensor is checked.
1 tC can be accompanied by this pattern: 1 tC appears and drying may pause or performance may change because of temperature / temperature-sensor error.
On affected Samsung dryer models, 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.
To rule out an accessible cause, record when the code appears and whether the appliance had just heated, cooled, or defrosted.
As an external check for 1 tC, confirm vents, doors, filters, and ambient conditions are normal where they affect the sensor reading.
Before requesting service for 1 tC, use the exact model manual before assuming the sensor itself is defective.
For 1 tC, start by doing this: record the code and whether the dryer is vented or heat-pump/ventless.
With 1 tC recorded, clean/inspect lint filter, heat exchanger, water tank/drain, and external vent only when relevant.
The next non-invasive check is to 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 1 tC would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
For 1 tC, the service threshold is straightforward: Persistent temperature-sensor codes usually require resistance/connection checks at the sensor, harness, and control—work best done with the model-specific service procedure. Bring the exact model number and a photo of the display so the diagnosis stays tied to the documented Samsung code.

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 **1 tC** 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 **1 tC** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
No. **1 tC** tells you which condition or check the control detected. The same display can result from the named component, its wiring, a connector, a supply/airflow/water condition, or the control that reads it.
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 1 tC** separate from same-looking codes used by other Samsung appliance families.
