Read the accompanying symbol and the model's alarm description. The sound alone may not distinguish a door-open warning from an elevated-temperature warning.
What the observation tells you
Closing the door may address one condition while the temperature still needs to recover. Conversely, a temperature warning may remain after a brief opening even when no physical gap is present. Randomly pressing controls can erase the useful distinction.
A useful next step
Note the display and timing, check ordinary closure without force and monitor suitable storage. If the cause remains unclear or food is thawing, use the relevant safety guidance and arrange assessment.
