Condensation in a refrigerator is caused be the cool and warm air flow. When the dorr is opened warm air is pulled inside the unit and the cool air meeting it causes condensation to form on the walls of the unit.
The drip pan on your refrigerator is a receptacle that catches condensation flowing from the defrost drain in your freezer to the outside of the refrigerator where it can evaporate. Occasionally you may need to get to the drip pan to clean it, remove a blockage in the drain line or perhaps to repair it. Finding the drip pan is simple and takes only a moment if you know where to look. While refrigerators vary in design, the drip pan is almost universally located in the bottom of the unit.
