A simultaneous interruption can indicate a shared supply event rather than several independent appliance failures. The timing helps direct assessment without proving the exact electrical cause.
What the observation tells you
Keep separate notes for what each appliance actually did. A kitchen light going out is different from one refrigerator display resetting. Do not test the circuit by repeatedly reconnecting equipment or by swapping protective devices.
A useful next step
Tell the booking team when the event occurred and whether power elsewhere was affected. Use a qualified electrician where the supply is suspect. Continue to assess the fridge's actual cooling and the food's storage history separately.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
