Samsung Refrigerator Error Code Refrigerator Med

Refrigerator Med indicates a fault with the RD-sensor, also called the R-room defrost sensor. The control board has detected a temperature reading from this sensor that is above +50°C or below -50°C, both of which are outside the valid operating range. This typically points to a disconnected sensor connector, a wiring open or short circuit, or a failed sensor rather than an actual extreme temperature condition.

A reset may temporarily clear the error code from the display, but it will return as soon as the control board reads the sensor again. Because the fault is caused by a hardware issue such as a loose connection, broken wire, or failed sensor, the underlying problem must be repaired for the code to go away permanently.

If only the RD-sensor needs replacement, parts typically range from around $15 to $50 depending on the specific model, and the repair is relatively quick for a technician. If the issue involves wiring repair or harness replacement, labor and parts combined could range from $100 to $250 or more. A simple reseating of a disconnected connector costs nothing beyond the time to diagnose it.

In many cases, yes. Start by locating the R-room defrost sensor inside the refrigerator compartment and checking that its connector is firmly seated. If the connection looks secure, use a multimeter to test the sensor's resistance. If the sensor reads open or shorted, replacing it is a straightforward repair that most technically inclined homeowners can handle with basic tools.

The refrigerator may continue cooling in the short term, but the defrost system is compromised when this error is active. Without reliable defrost sensor feedback, ice can accumulate on the evaporator coils, eventually blocking airflow and causing the refrigerator to warm up. It is best to address the fault promptly to avoid food spoilage or further component damage.
