Include nearby equipment
State whether other equipment lost power at the same time and whether a warning appeared when power returned. Repeated trips should not be recreated for a demonstration.
Protect stored food
Keep unnecessary door opening to a minimum while arranging appropriate food storage. The engineer needs the complete model and sequence to determine whether suitable inspection is available.
A useful distinction
The state after power returns also matters: normal display, warning or repeated blanking are separate outcomes. An appliance that briefly lights up should not automatically be described as recovered if freezing remains poor.
