  2. Place dry towels on the floor around the refrigerator to catch any water as the ice melts.
  3. If an ER FF or ER rF error code appears, the fan motor in the freezer or refrigerator compartment may not be working properly. Ice or frost buildup around the fan motor usually prevents it from turning. To resolve the issue, unplug the refrigerator and leave both doors fully open for at least 24 hours. Allow any ice or frost inside to thaw naturally before plugging the refrigerator back in.
  4. This indicates that your freezer fan motor is not operating properly. Ice or frost buildup around the motor usually prevents the fan from turning. This often happens when the freezer contains too much food or the door is not fully closed, allowing outside air to enter.
