Samsung · Refrigerators
The freezer's displayed temperature immediately reverts to a positive 7 degrees (implying Celsius or Fahrenheit, indicating it's too warm for a freezer) within seconds of being set to a lower, colder temperature. This points to a control board or temperature sensor malfunction.
Click steps to track your progress.
Unplug the Refrigerator for at least 10-15 minutes to perform a hard reset of the control system.
Plug the unit back in and attempt to set the freezer temperature to the desired cold setting again.
Check the user manual for any specific reset procedures for the control panel or temperature settings.
If the temperature continues to revert, the control board or sensor may need to be replaced by a qualified technician.
