Click steps to track your progress.

1. 1

   Unplug the Refrigerator from the power outlet for at least 15-30 minutes to reset the system.

2. 2

   Plug the Refrigerator back in and allow some time (e.g., an hour) for the system to fully reset and stabilize.

3. 3

   Avoid pressing buttons during this stabilization period, as it might interfere with the reset process.

   If the issue persists, the R DEF sensor or related wiring might need inspection by a technician.
