Copy the whole indication
Include symbols, flashing and which buttons were used. State whether there was a power cut and whether the control returns to a previous setting.
Relate it to storage
Describe any observed change to food separately. A professional can assess control behaviour, but display information alone cannot establish food safety or a specific failed cooling component.
A useful distinction
If the number appears only after pressing a control, say so. A service enquiry based on a supposed measured temperature may be misdirected if the panel was actually showing the requested setting or a special mode.
