Samsung Refrigerator Error Code 13E — What It Means & How to Fix It

What Does This Error Mean?

The 13E error on your Samsung refrigerator indicates a problem with the humidity sensor or an environmental sensor used by the smart features. Some Samsung models use humidity sensors to optimize the cooling and moisture control in the fresh food compartment. When this sensor malfunctions, 13E appears.

Affected Models

Samsung RF28 and RF23 French Door series
Samsung Family Hub refrigerators
Samsung models with Fresh Zone or humidity-controlled drawers

Common Causes

The humidity sensor has failed due to age or moisture damage
Condensation buildup inside the sensor housing has caused a false reading
The wiring connector to the sensor has come loose
Food residue or liquid has contaminated the sensor
A power fluctuation has disrupted sensor communication with the control board

How to Fix It

Unplug the refrigerator for five minutes, then plug it back in to perform a full power reset.

A temporary sensor glitch from a power issue often clears after a proper reset.
Check the fresh food compartment walls and any humidity-controlled drawers for excessive moisture, condensation, or food spills.

Moisture around the sensor housing can cause false readings and trigger 13E.
Remove any humidity-controlled drawers and clean around the sensor area with a dry cloth.

Allow the area to dry completely before replacing the drawers.
If your refrigerator has a Samsung Smart Hub or connected features, check the app for additional diagnostic information about the error.

Samsung's SmartThings app can provide more detailed error descriptions for connected models.
If 13E returns after a reset and cleaning, contact Samsung service. The sensor requires professional testing and replacement.

Samsung's service team can access diagnostic mode to confirm the sensor fault before ordering parts.

When to Call a Professional

If a power reset does not clear 13E, a technician should locate and test the humidity sensor on your specific model. Sensor replacement is typically $80–$150 including labor. The sensor location varies significantly between Samsung refrigerator models.

Frequently Asked Questions

Does 13E affect food safety in my Samsung refrigerator?

The main cooling system continues to operate normally with 13E. However, if the humidity sensor controls moisture-related features in your fresh food drawers, produce may not stay as fresh as usual. Monitor food freshness more carefully until the error is resolved.

Is 13E a common error on Samsung refrigerators?

It is less common than ice maker errors (8E, 11E) or temperature sensor errors (1E, 2E). It primarily appears on higher-end Samsung models with humidity-sensing features. A simple power reset resolves it in many cases.

Can humidity in my kitchen cause 13E?

Very high kitchen humidity can contribute to moisture-related sensor issues. Make sure the refrigerator is not located next to a steam-producing appliance like a dishwasher or range without adequate ventilation. Proper spacing and kitchen airflow help prevent moisture-related sensor faults.
