One of the most common questions of our time is why the refrigerator does not cool, but it works. The logical conclusion is – a malfunction, it remains only to find out which one. After all, it happens that the refrigerator makes a loud noise, does not cool, and the freezer functions or vice versa. The purpose of this material is not only to identify the causes and solve the problems that have arisen but also to enable users to eliminate the risks of their re-formation.
Introductory information – types of refrigerators
The main classification of all refrigerators is generation. New advanced models differ in the set of functions, however, the principle of operation of the devices is almost identical.
There are different refrigerators:
♦ design features (single and double chamber, standard, side by side, built-in, cabinets, and others);
♦ the type and number of compressors used;
♦ cooling method;
♦ type of defrosting;
♦ level of energy saving;
♦ type of refrigerant used and other important characteristics.
Despite the variety of modifications, the answer to the question of why the refrigerator does not cool may lie in the simplest.
What to check in the first place?
First of all, it is necessary to analyze the operating conditions of the device. Most often, users themselves, who do not follow the manufacturer’s instructions, become the source of all troubles.
Important recommendations and safety rules
Do not put yourself and your equipment at risk! Be sure to disconnect the device from the mains, and provide airflow (ventilation) when replacing the refrigerant. And also use personal protective equipment (gloves, respirator, electrostatic measuring devices, etc.).
Main causes of malfunction
The primary task for the user is to analyze the operation of the refrigerator. Examine and evaluate the following factors:
1. Tightness of the door fit. Make sure that it is not obstructed by the closing mechanism and door closers if any. Check whether food, objects, dishes, etc. do not go beyond the shelves and compartments stored in the refrigerator. Inspect the strength of the hinges of the door. Analyze the degree of wear of the seal. Perhaps the “tightness” of the chambers is broken.
2. Correctness of installation. Heat sources – heaters, radiators, stoves, ovens, and others – are not located too close to the refrigerator. Due to the high-temperature difference (external and internal environment), the compressor fails, unable to cope with cooling.
3. Inappropriate mode. The refrigerator compressor is also overloaded by extremely low internal temperatures, especially in summer. Incorrect settings lead to the fact that all cooling resources are directed to the freezer. Avoid frequent use of the minimum and maximum modes. They are set in individual cases and for a short period of time. This is one of the most common reasons why the refrigerator does not cool, and icing of the internal chambers (or snow coat) occurs.
4. Failure of the fan in the No Frost system. You can detect the problem by ear. You should listen to whether there is a characteristic sound of rotation of the cooler blades during operation. Often a layer of ice forms around the fan, which prevents the device from functioning.
If there is no sound, try defrosting the refrigerator. If the problem persists or recurs after a few days, then the cause of the breakdown is in the functional elements.
Please note! It is recommended to defrost the refrigerator for at least 10 hours.
Some models have an internal defrost button. Its arbitrary pressing or clamping (by stored items), oddly enough, leads to the fact that the refrigerator does not cool. And such a “breakdown” is quite common. Banal carelessness in this case plays a key role and can lead to a complete stop of the cooling system.
