Samsung Refrigerator Error Code Refrigerator LOW·Med

The LOW·Med error code points to a fault with the R2-sensor, which is the right-side temperature sensor in the refrigerator compartment. The control board has detected a temperature reading from this sensor that is above +50°C or below -50°C, which falls completely outside the normal operating range. This indicates the sensor circuit has a problem such as a disconnected housing, damaged wiring, or a failed sensor. The refrigerator may not maintain proper cooling while this fault is active.

A reset may temporarily clear the error code from the display, but it will return if the underlying problem with the R2-sensor, its wiring, or connector has not been corrected. Unplugging the refrigerator for a few minutes and restoring power is a common reset method, but this should be treated as a diagnostic step rather than a fix. The root cause must be identified and repaired for the code to stay cleared.

If the fix is simply reseating a loose connector, there may be no parts cost at all, though a service call will typically range from $75 to $150 depending on your area. If the R2-sensor needs replacement, parts and labor together generally fall in the range of $100 to $250. Wiring harness repairs or replacements can vary more widely depending on the extent of the damage and the specific model.

Some causes of this error are DIY-friendly. Reseating a loose sensor connector or inspecting the wiring harness for visible damage requires only basic tools and careful attention. However, testing sensor resistance with a multimeter and replacing wiring or the sensor itself requires some technical comfort with appliance repair. If you are not confident working with electrical components inside the refrigerator, a qualified technician should handle the repair.

A faulty R2-sensor means the control board may not have accurate temperature data for the right side of the refrigerator compartment, which can affect cooling performance and food safety. It is advisable to check the actual internal temperature with a standalone thermometer and limit storing perishable foods until the sensor issue is resolved. Continuing to run the unit for an extended period without addressing the fault risks food spoilage.
