Use the highlighted compartment, flashing value or symbol described by the manual. One buzzer may serve several conditions, so the sound alone is not enough.
What the observation tells you
A freezer temperature warning and a fridge door warning can require different actions. Silencing the sound before reading the panel removes useful evidence. On some models the display alternates, so allow the normal sequence to be observed without changing controls.
A useful next step
Record the entire message and both compartment conditions. Check normal door closure and food storage as relevant. Seek clarification if the indicator is unreadable rather than assuming the nearest door caused it.

Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
