Would be nice to know what happened to repair it.
The info you provided was good, It should be fixed by now.
Just my opinion, That system should have shut down before icing up that way.
Most systems look at High Pressure for safety cutoff, But if it is low on refrigerant it can run forever, and is very well Cooled.
Hope to hear a report soon.
