Have you ever noticed the hole on the back wall of your refrigerator? Most of the time it is hidden behind the food. However, it has an important meaning for the functioning of the refrigerator.

Have you ever noticed it? At the back of the rear wall in the refrigerator there is a small hole. And this one has quite an important function. If you know about it, you will realize that it is worth paying a little more attention to the inconspicuous hole every now and then.

Hole in the refrigerator has an important function

The small cavity is probably mostly hidden behind the food in your home as well. It is responsible for regulating the amount of condensed water in the refrigerator.

The condensed water that collects on the back wall drains through the hole via an inclined device. From here it flows into a container, from where the water evaporates. If the water cannot drain through the hole, small puddles may form in the refrigerator. Therefore, you should regularly check whether the hole is clogged or needs to be cleaned.

How to clean the condensation drain properly

Keep sharp objects away from the drain hole as far as possible. Instead, use a cotton swab or – for more stubborn dirt – a toothpick to clean it. A little vinegar can also be used to disinfect.

What if mold has formed?

However, if mold has formed in the small hole, a simple cleaning will not be enough. In this case, the refrigerator must be defrosted and thoroughly cleaned.
