Cause 1. Problem in the defrost sensor
The most common source of this seemingly minor malfunction is if the defrost sensor no longer manages its task. A luxuriant frost coat or ice crust eloquently symbolizes that the chamber has experienced permafrost. The refrigerator unfreezes in time, not completely or not completely defrosted, and of course, the built-in motion sensor is to blame for this.
What to do: go to the workshop. The built-in parts should not be replaced or repaired if you did not have a successful similar experience in the past.
If the frost on the wall is not there, then observe the timing of its appearance and disappearance. The sensor arranges defrosting in a timely manner, if in the refrigerator with one compressor on the wall the frost lasts 15 minutes, after which it melts for 35 minutes, and the ratio of 25 minutes of freezing and 25 minutes is normal for a two-compressor cabinet.thawing.
Reason 2. Incorrect operation of
Yes, yes, only at first glance it seems that you do not need to learn to use the refrigerator. In fact, the subtleties are in the manual to any clever modern technique.
The worst effect on the performance of the device is non-observance of the temperature regime. The owners do not want to wait for the pots and dishes to cool down, and put them on the shelves still hot, mistakenly thinking "what will it be?".In fact, an excessively high temperature can significantly knock down the settings of the defrost sensor or completely disable it, and as a result, thawing will not occur correctly.
It's not that rare when a refrigerator is simply forgotten to be closed. Warm indoor air with moisture enters the refrigerator, condensate settles on the back wall, and the refrigerator starts to freeze harder to maintain the set temperature. This is the cause of intent. If the "symptoms" are the same, but the door is closed properly, there may be a problem with the following reason.
Reason 3. The sealer is not the
The problem of a very hike in its manifestations for misuse, but the frost and frost cap may also appear on the walls of the unit. Do not wait for the ice to fill the chamber - replace the worn insulation. This can be done with your own hands, the main thing is to find the right material for your model. Different erasers are differently attached to the rubber band, therefore, replacement should be made in accordance with the type of attachment - on the glue, on the screws or with the help of grooves.
Reason 4. Case in the compressor
The most unpleasant of all the reasons why the rear wall of the refrigerator intends, there may be a breakdown or incorrect operation of the compressor. Identify this for sure only a master.
The camera from the inside can turn into real snow-covered Alps, if you do not notice the leakage of the coolant. With its shortage, the compressor operates without interruptions and, accordingly, warms, raising the temperature of the entire refrigerator. From here and frost.
The four listed reasons are the main ones, because of which the rear wall of the refrigerator intends. But why the wall of the refrigerator is heated? The answer to this question is extremely simple: this is the device of the unit, that in the intervals between the compressor's sessions, the heated liquid for cooling is supplied there. In many models, the condenser tubes in which this process occurs are located just in the side walls.
It is best to solve the problems that arise with the refrigerating cabinet, with the help of specialists and not risk the serviceability of machinery. Refrigerators are fragile enough devices, therefore, having no experience, it is better to trust the masters.
