Window units ice up for two reasons: a dirty filter restricting airflow, or running in weather too cool for the thermostat setting. Both are common, and both look alarming without being a failure.
Owners can wash the filter monthly in season and check the unit tilts very slightly outward so condensate drains away from the room. Sealed-system and electrical work requires a technician with the unit unplugged.
