Why does a fridge freeze and what can be done about it?


Especially in older refrigerators is sometimes ice, even modern devices with automatic defrosting are not completely immune from it. The reasons for this are manifold, as well as the possibilities to fight the causes, which prevent the icing in the future or at least slow it down. But the real symptom, the ice, you fight only by defrosting!

Causes of an iced refrigerator

Inside the refrigerator there are different temperature zones, at the back wall it is the coldest. Even though most of the middle compartment is at the recommended 7 degrees Celsius, it can be quite cold in the back area.

In addition to the cold, ice formation needs another component to get going: the water. The more moisture in the fridge, the faster the ice will form on the coldest.

How does the water get into the fridge? There are several causes for this, some of which can be turned off quite easily. A source of this could be too much heat, because from warm air precipitates in cool places condensation.

How to defrost your fridge thoroughly

You have fixed the causes of ice formation, now only the ice has to disappear? To defrost, remove the refrigerator from the mains and remove all food. Then proceed as follows:

  • place absorbent cloths in the refrigerator to absorb the water
  • possibly show pots and baking tray
  • Thaw ice with hair dryer faster (Attention: keep a distance of about 30 cm!)
  • Gently remove ice floes with a soft scraper
  • After defrosting, thoroughly clean the refrigerator
  • use vinegar water for disinfection and odor neutralization
  • Dry all refrigerator elements carefully
  • Put the device back in, connect to the mains, close the door
