Click steps to track your progress.

1. 1

   Unplug the Refrigerator for at least 24-48 hours with the freezer door open to allow all ice to completely melt.

2. 2

   Manually remove any accessible ice buildup from the back panel and drain area after unplugging.

3. 3

   Plug the Refrigerator back in after full defrosting and monitor if the issue returns.

4. 4

   If the problem reoccurs, a specific defrost component (heater, thermostat, sensor) or the control board may need replacement by a technician.
