The simplest reason for a strong frost is the switching of the thermostat to a lower temperature regime. This happens very rarely, but sometimes it happens. If you do not know why the refrigerator freezes food too much, first check this point. The optimum value at which the regulator should be set is 2-3.5.If you cool the new refrigerator, set the temperature on the dial to +4 / + 6 degrees.
By the way, in the newer models of technology there is a super-frost button. Check if it is already on. Perhaps the reason for the severe frost is that someone accidentally turned on this mode!
The second fault, due to which the refrigerating chamber can freeze food more than necessary - damage the seal on the door. A clear sign of damage to the rubber is the formation of icing in the freezer and a small puddle of water that has not yet frozen. In the cold store at this time, it is possible to freeze the snow heavily on the back wall, because of which the food freezes. Replace the elastic band on its own or simply restore, should not make you hard, which confirms the video lesson below!
The third failure is the clogging of the drainage hole under the boxes for fruit and vegetables. Drainage is needed in order for condensate from the walls to drain from the refrigerating chamber. If the holes are clogged, the water will remain in the vegetable tray and freeze, greatly freezing the food in the refrigerator. To clean the drainage holes is not at all difficult, you just need to unfreeze the camera and pour warm water into the area of the blockage( perform a syringing device).
If you are overzeared by a new refrigerator with the function No Frost, we recommend you watch this video:
Now we turn to more complex breakages, which you can hardly repair yourself. If the recommendations above did not help you, then the problems in the technical part and for repair will have to be called by the master!
If the refrigerator gets very cold and does not turn off, the refrigerant most likely escapes from the system - freon, due to which the temperature in the chambers is lowering. The reason for the leakage of freon is the appearance of microcracks in the cooling system or blood clots. Specialists can quickly find cracks, solder them and fill the necessary amount of Freon for work( or clean the blood clots).For other reasons why the refrigerator works and does not turn off, you can read in the relevant article.
Also likely the culprit of the fact that the refrigerating chamber began to strongly freeze the snow on the back wall, there may be a failed thermostat. This circuit element breaks down either as a result of mechanical damage or moisture contact on the contacts. Try to find a thermostat, visually inspect it and if you know how to - ring the tester. If the thermostat does not work, just replace it and solve the problem of severe frost.
We draw your attention to the fact that thermostats are installed in refrigerators with electromechanical control( older ones).New models are equipped with an air sensor, which must also be found, checked and replaced if necessary!
Well, the last, sixth reason why the bottom camera is very cold, and the upper one does not freeze is the sticking of the valve, which just helps to switch the cooling modes of different compartments. A broken valve should be found and replaced with a working one.
That's all the reasons for the malfunctions. We hope that now you know what to do if the refrigerator is very cold and why it can happen! We draw your attention to the fact that these recommendations are suitable for all firms of technology, from Atlanta to Samsun and Liebher!
