Visible frost or ice buildup on the outside of the evaporator tubing or nearby components.

Safety first: Unplug the unit before defrosting.

Step-by-step:

• Defrost: Leave the lid open and allow frost to melt naturally. Wipe away water.
• Check lid seal: Ensure the lid closes fully and the gasket is intact.
• Reduce humidity: Use the ice maker in a less humid room if possible.

When to call a technician: If frost forms rapidly and heavily, there may be an insulation or airflow issue that needs professional evaluation.
