Possible Causes

Room temperature too low, Restricted airflow from dirty filter or coil, Low refrigerant charge, Faulty defrost sensor or control

Safety: Unplug the unit and allow all ice to melt before further inspection.

Steps:

Room temperature: Ensure the room is above the minimum operating temperature. Move to a warmer area if necessary.
Airflow: Clean the air filter and coils to restore proper airflow.
Defrost sensor: Check that the defrost/coil sensor is attached correctly and replace if faulty.
Refrigerant: If icing persists despite good airflow and sensors, a refrigerant issue may exist and should be checked by a technician.
