Well, at number 9 it is TOO much and maybe the freezer is already saturated with ice, therefore it doesn't freeze or cool down, I guess it's not frost or I'm wrong? you have to check the coil how much frost it has, removing the false cover can be seen, if it has almost no frost: these could be 3 possible failures: possible leakage, or that the filter is partially covered or the compressor is already lacking , it would be a good idea to check with the pressure gauges, now if it is super saturated with ice, the entire freezer and drain must be defrosted and the automatic defrosting system checked, greetings
