Possible Causes

Low airflow due to dirty filter or fan issue, Low refrigerant charge, Very low indoor temperature setting, Faulty evaporator temperature sensor

Safety first: Turn off the unit to allow ice to melt. Place towels under the unit to catch water.

Clean filters: Ensure filters are clean and dry.
Check fan operation: Confirm the indoor fan runs at normal speed.
Increase set temperature: Avoid setting the thermostat extremely low in cool mode.
If icing recurs: Have a technician check refrigerant charge and sensor operation.
