Water in the fridge? The five most common causes and what helps against them. The most common cause of too much condensation is a clogged drain.
A defective door seal can allow warm air to enter the refrigerator, which in turn promotes the formation of condensation. Food or foods that are too warm lead to increased condensation and this is exactly what needs to be avoided. The Munich kitchen studio Elha Service recommends cleaning the drain with a toothpick, wire, pipe cleaner or similar small objects.
