Samsung Refrigerator code **1C** is associated with **freezer temperature sensor error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. 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 **1C**. Search normalization stores it as **1C** while preserving the characters a homeowner actually sees.

Quick answer
Freezer temperature sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 1C 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
Samsung Refrigerator code **1C** is associated with **freezer temperature sensor error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. 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 **1C**. Search normalization stores it as **1C** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
1C can be accompanied by this pattern: the control may stop or limit operation because a temperature reading is missing or implausible.
1C can be accompanied by this pattern: heating, cooling, drying, or defrost behavior can become inconsistent.
While 1C is active, the display may return at a similar stage each time the affected sensor is checked.
Depending on the exact model, 1C appears and the refrigerator may show behavior related to freezer temperature sensor error.
Depending on the exact model, cooling, airflow, ice-making, defrost, or temperature performance can become intermittent depending on the affected subsystem.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
For 1C, start by doing this: record when the code appears and whether the appliance had just heated, cooled, or defrosted.
For 1C, start by doing this: confirm vents, doors, filters, and ambient conditions are normal where they affect the sensor reading.
As an external check for 1C, use the exact model manual before assuming the sensor itself is defective.
Before opening any service area, photograph the code before resetting or unplugging the refrigerator.
Before opening any service area, check doors, visible airflow/ice obstructions, water/ice-bin seating, or demo mode only when relevant.
Before opening any service area, use the exact model manual because Samsung refrigerator codes vary by family.
Important safety warning. Protect food if temperatures are no longer safe. Do not open the sealed refrigeration system or energized inverter/compressor circuits. If resolving 1C 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. In a service visit for 1C, model-specific testing should follow the freezer temperature sensor error circuit rather than treating the code as proof of one failed part.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
Resetting can clear a temporary state, not a persistent issue. If **1C** comes back, preserve the code and move to the safe checks or model-specific service path.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **1C** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **1C** 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 **Refrigerator 1C** separate from same-looking codes used by other Samsung appliance families.
