Record both controls
Some appliances share a setting and others control compartments separately. Copy labels or symbols and use the matching manual for ordinary settings.
Compare the actual outcome
Do not assume a restored display means storage has recovered. Include compartment results and warnings. If cooling remains poor, service boundaries need checking before any appointment is promised.
A useful distinction
Keep the duration of a known outage separate from how long the appliance has been back on. Those are different intervals, and neither provides a remote guarantee that stored food has remained safe.
