The main function of a refrigerator is to store food at low temperatures. However, sometimes it begins to freeze too much, which indicates a malfunction of this household appliance. There can be several reasons why the refrigerator freezes too much and, often, some of them can be eliminated at home.
If you happen to encounter such a problem, first of all check the settings. If the operating parameters are set on the appliance mechanically, the temperature regulator should be set at 2 to 3.5. For an electronic model, you choose a temperature mode from +39.2 to +42.8 degrees. If the parameters are set correctly, but the refrigerator still continues to freeze too much, you should look for another cause of malfunction.
The main signs that the refrigerator is generating excessive cold
In order to understand why your refrigerator is freezing too much, pay attention to the presence (absence) of the following signs:
- The appliance is equipped with NO FROST system, but water accumulates in the freezer compartment and forms ice on its walls.
- Ice has formed in the vegetable and fruit storage compartment and water has formed directly under the container itself.
- The appliance is very cold, even when the freezer is off.
In general, the main indicator of excessively low temperature in the refrigerator is the presence of ice in it.
Elimination of excessive freezing in the appliance depending on the cause of the malfunction
To solve the problem of the presence of too much frost in the refrigerator, first of all, you should determine the cause of its occurrence. If the breakdown is not serious, you can try to fix it yourself, but if you encounter difficulties when trying to fix the unit, only a professional can help fix the situation. Remember, complex faults should not be repaired by yourself, because “intervention by ignorance” can only aggravate the situation.
Setting the temperature regulator to the lowest temperature setting
One of the most common causes of excessive cooling of food in the refrigerator. Often, the thermostat can switch to the lowest setting spontaneously. Hence, it is advisable to periodically check the location of the regulator. Newer models also have a hard freeze button. If you are the owner of such an appliance, it is worth checking it as well, in case it is on or stuck.
Damaged seal (rubber band) on the refrigerator door
Over time, the seal located on the refrigerator door can wear out, making the degree of adherence of the door to the appliance will be lower than it should be. This leads to the penetration of warm air inside. Because of the heat intake, the humidity increases, which means that excessive condensation is formed, flowing down the drain. Fixing this problem is quite easy – simply replace the seal. Thanks to this, the refrigerator will be restored to its former tightness and the temperature will be optimized.
Clogged drain hole
In most models, this vent is located underneath the fruit and vegetable storage containers. When it becomes clogged, the temperature setting deviates from the settings. If the hole is clogged, the condensate formed in the refrigerator does not drain and remains in the tray. Gradually the liquid begins to freeze, which, in turn, negatively affects the food inside. To clean the hole, you need to completely defrost the appliance and pour warm water into the place of the blockage.
Lack of freon
If the refrigerator runs out of freon, the pressure in it begins to drop. Decreased pressure leads to increased work of the compressor, as it has to maintain the necessary temperature regime in the freezer. Hence, unplanned temperature changes and excessive cold inside the unit. To solve the problem, the unit should be charged with freon. There are situations when the freon did not run out, but simply leaked out due to cracks or other mechanical damage. In this case, it is necessary to contact a specialist to conduct a full diagnosis of the breakdown.
Clogged or broken valve between different parts of the refrigerator
The valve is needed to switch the temperature modes in different parts of the refrigerator. If it is defective, then in the lower compartment there will be excessive cold, and in the upper compartment – no cold. To fix the problem, it is necessary to replace the faulty valve with a working one.
How to find the cause of the malfunction yourself
To determine the cause of the malfunction, perform the following steps:
– Check the settings – if the previously set parameters have been knocked out, you should restore their correct values. If the settings are OK, you should continue with the diagnostics.
– Inspection of the seal – it is important that it ensures a tight fit between the door and the unit itself. If the seal is worn, a new rubber should be purchased and replaced.
If both the settings and the seal are normal, then the cause of the malfunction lies in something else. Since it is quite difficult to repair the refrigerator yourself if there is a freon leak, a clogged drain or a broken valve, it is recommended to contact a specialist to fix these problems.
