The earlier event may help explain the appliance's subsequent operation, especially on designs with related cooling or airflow functions. It is useful history rather than a confirmed cause.
What the observation tells you
Moisture and ice may develop while a door remains open. The fridge problem could also be unrelated, so do not omit either observation or assume one new part will explain both. Avoid recreating the event deliberately.
A useful next step
Give the sequence, known duration and visible frost pattern. Protect each food group appropriately and follow the model instructions. Persistent abnormal performance needs assessment.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
