If a Samsung refrigerator shows **94C**, the verified Samsung meaning in this research set is **sparkling tank water-supply / level-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 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 **94C**. Search normalization stores it as **94C** while preserving the characters a homeowner actually sees.

Quick answer
Sparkling tank water-supply / level-sensor error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 94C 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 refrigerator shows **94C**, the verified Samsung meaning in this research set is **sparkling tank water-supply / level-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 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 **94C**. Search normalization stores it as **94C** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
While 94C is active, the control is not receiving an expected sensor signal or the signal is outside its accepted range.
When the 94C condition is present, the appliance may stop a feature, limit operation, or repeat the code during the same stage.
A symptom that fits 94C is that the affected function can behave intermittently if the signal or connection is unstable.
On affected Samsung refrigerator models, 94C appears and the refrigerator can show behavior related to sparkling tank water-supply / level-sensor error.
One clue that supports the 94C diagnosis is that 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.
As an external check for 94C, photograph the code and note the exact operating stage when it appears.
A safe owner-level check is to check only user-accessible conditions that can physically affect the monitored function.
Before requesting service for 94C, avoid replacing a sensor solely from the display; wiring, connectors, supply conditions, and the control can create the same result.
With 94C recorded, photograph the code before resetting or unplugging the refrigerator.
To rule out an accessible cause, check doors, visible airflow/ice obstructions, water/ice-bin seating, or demo mode only when relevant.
With 94C recorded, use the exact model manual because Samsung refrigerator codes vary by family.
Important safety warning. Safety takes priority over clearing 94C. Protect food if temperatures are no longer safe. Do not open the sealed refrigeration system or energized inverter/compressor circuits.

When to request repair service
If the code returns, model-specific sensor, harness, connector, and control-board testing is appropriate. A repeatable 94C event is more useful diagnostically than repeated resets, because it shows when the sparkling tank water-supply / level-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 **94C** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **94C** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **94C** 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 94C** separate from same-looking codes used by other Samsung appliance families.
