water forms on bottom of fridge under crisper

Water is forming on the bottom of the fridge under the crisper because the fruit and vegetable bin retains high humidity, which may produce small amounts of water. This is normal and can be wiped out as needed. If excessive water forms, storing fruit and vegetables loosely wrapped in plastic bags and setting the humidity slide to a low setting may help reduce moisture buildup.

The Fisher & Paykel E373 fridge may freeze up due to the temperature setting being too low or because chill-sensitive foods are placed directly in front of the air outlets.
