Samsung Refrigerator Error Code Freezer LOW·Med

The Freezer LOW·Med code indicates a fault with the F-room sensor, which is the temperature sensor located in the freezer compartment. The control board is receiving a temperature reading above +50°C or below -50°C, which is outside the physically valid range. This signals a problem with the sensor connection, wiring, or the sensor component itself rather than an actual temperature emergency. The refrigerator will typically display this code until the sensor circuit is repaired.

A power reset may temporarily clear the error code from the display, but the code will return if the underlying sensor or wiring fault has not been corrected. Resetting is useful for confirming whether the fault is intermittent or persistent, but it is not a repair. The root cause in the sensor circuit must be identified and addressed for the error to stay cleared.

If the fix is simply reseating a loose connector, there is no parts cost involved. A replacement F-room sensor typically costs in the range of $15 to $50 depending on the specific model. If a professional technician is needed, expect labor costs to add $75 to $200 on top of parts, though total cost will vary based on your location and the technician's rates.

Many cases of this error can be resolved without professional help if the cause is a loose or disconnected sensor connector. Start by locating the F-room sensor in the freezer compartment and checking that its wiring plug is firmly seated. If the connector is secure, checking the wiring for damage and testing sensor resistance with a multimeter are reasonable next steps for a knowledgeable DIYer. If the sensor itself has failed, replacing it is a straightforward repair that involves disconnecting the old sensor and installing a compatible replacement.

Because the sensor is not reporting accurate temperature data, the refrigerator may struggle to maintain proper freezer temperatures, which could put frozen food at risk over time. If the error has just appeared, check the freezer temperature manually and monitor it closely. If the freezer is not maintaining safe temperatures, transfer frozen food to an alternative location until the sensor is repaired.
