Did you know refrigerators are designed to remove moisture that is inside the unit? If there is too much moisture, condensation can build up on the interior of both the refrigerator and freezer in the form of frost and ice. Before putting anything in the fridge, make sure it has a lid or cover, since uncovered containers transfer moisture into the air. Water-rich produce like iceberg lettuce and celery can be problematic; cover them in paper towels, which will help absorb excess moisture. And avoid opening and closing the fridge too many times if it's warm inside the home. The influx of warm air can create too much moisture.
