Samsung Refrigerator Error Code Refrigerator LOW

The Refrigerator LOW error code indicates a fault with the R1-Sensor, which is the R-room left temperature sensor inside the refrigerator compartment. The control board is receiving a temperature signal that is either above +50°C or below -50°C, which is outside the physically possible range for normal operation. This points to a connection problem, wiring fault, or a failed sensor rather than an actual temperature extreme. The code requires inspection of the sensor, its connector, and the associated wiring harness.

A power reset may temporarily clear the LOW error code from the display, but the code will return if the underlying fault with the R-room left sensor, its wiring, or its connector has not been corrected. Resetting is useful for confirming whether the fault is intermittent, but it is not a fix. The sensor circuit must be inspected and the root cause addressed to permanently resolve the error.

If the fix is simply reseating a loose connector, there is no parts cost involved. Replacing the R-room left temperature sensor typically involves a parts cost in the range of $15 to $50 depending on the specific model. If a technician is needed for diagnosis and repair, expect total service costs in the range of $100 to $250, with higher costs possible if the wiring harness requires repair or if the main control board is ultimately involved.

A homeowner or experienced DIYer can attempt to resolve this error by first checking that the R-room left sensor connector is fully seated and free of corrosion. If the connector looks secure, testing the sensor with a multimeter to check its resistance is a straightforward next step. Replacing a faulty thermistor sensor is a relatively accessible repair, though tracing and repairing a damaged wiring harness may require more technical skill.

When this error is active, the refrigerator may not be able to accurately monitor or regulate the temperature in the left section of the compartment. If the unit has been running noticeably warm or if you are unsure how long the error has been present, check the actual compartment temperature with a separate thermometer. Food held above 40°F for more than two hours should be evaluated carefully before consumption.
